* 2004/01/24:
  -----------

- Version 0.85.9

- 'done' log file contains upload log.

- fix the incorrect information sent to the UI when uploading a file bigger than
  2GB (only the display is buggy, the transfer works).

- update .spec file to support fedora (based on Sammy Atmadja modification).

--------------------------------------------------------------------------------
* 2004/01/04:
  -----------

- Version 0.85.8

- fix incorrect handling of "/IP interface" in both DCTC and dctc_master.

- .userinfo file updated to contains all connected users

- new flag added: disp_user. If set to 1 (default), incoming/outgoing users 
  generate USER+/USER- message else nothing is displayed.

- add .mkv as known file extension (video).

--------------------------------------------------------------------------------
* 2003/12/21:
  -----------

- Version 0.85.7

- /IP command accepts IP (like before) and also interface name (eth0, ppp0, ...)
  This can be useful if you have several outgoing interfaces and want to bind 
  DCTC to an interface which is not the default route. The command may also be
  used without parameter to reset DCTC to default interface. (WARNING: only the
  transfers are affected by the IP, not the hub connection. Some hubs does not
  like having a different IP for transfer and for hub connection).

- some annoying error messages are gone (moved into the debug code).

- minor modification of the "done" file. Each entry contains a timestamp.

- dummy_client status is set to "unconnected" instead of reporting a "connected"
  status without any valid hub.

- fix a bug in keyboard command processing which sometimes may use the wrong
  socket.

Note: I hope these 2 previous fixes will corrent the download problem appearing
  with some users.

- fix --disable-glib2 problem in the configure file. glib version >= 2.0 is
  required now.

- add missing thread attribute destruction.

- add missing -m switch to the help.

- hublist handles XML bzipped2 list.
  (see http://www.hublist.org/PublicHubList.xml.bz2).

- fix compilation problem when crypto library is libgcrypt and openssl is not
  installed.

--------------------------------------------------------------------------------
* 2003/10/26:
  -----------

- Version 0.85.6

- hublist and DCTC now support proxy requiring authentification.

- Some commands and variables were removed: /LINK, /NOLINK, /DLFORCE, /NODLFORCE
  /HIDE_ABS, /SHOW_ABS.

- dctc_link is now always enabled.

- Download force is removed.

- Absolute paths are now shown in the share list, they are modified in relative
  path (like /SHOW_ABS does).

- improve decoding of buggy user info message ($MyINFO).

- fix incorrect counting of upload slots if share list upload is always allowed.

- fix incorrect command sequence occuring if a GDL or an auto-scan starts during
  the hub connection establishment. Some hubs ignore the command, others
  complain and close the connection.

--------------------------------------------------------------------------------
* 2003/08/24:
  -----------

- Version 0.85.5

- when a dctc_master is created, gdl met params are inherited from the client
  creating it.

- support both libgcrypt (>=1.1.12) and openSSL as cryptography library.

- fix libtool compilation problem.

- add support of 64bits file API. This provides support of files bigger than
  2GBytes.

- Avoid auto-scan of simultaneously created/attached GDL to be started
  simultaneously. Previously, if you have no delay between search set, all GDLs
  start their auto-scan at the same time which can create a big network load and
  if you have a delay set, only the first GDL is able to run the auto-scan, 
  other queries are ignored.

- add flag to allow download of the sharelist even if no upload slot is
  available (sharelist_dl). If ==0, the upload is denied as usual. If not 0,
  the user can download the sharelist (a la DC++). 
  Based on A.J. patch.

- add 2 flags: fake_dcpp_client and fake_dcpp_version. When the first flag is 0,
  DCTC works in normal mode. If the flag is not 0, the 2nd flag must be set to a
  string containing the DC++ version to display (for example: 0.261 ).

- fix incorrect computation of the number of clients connected to a hub (useful
  if you use the description tag). The update of the number of hubs is also
  performed without delay.

--------------------------------------------------------------------------------
* 2003/07/12:
  -----------

- Version 0.85.4

- add .ogm as known file extension (video).

- new core to have a single process handling all transfers. 
   Note: before starting a process using this version, you must stop all process
         running an earlier version. See Documentation/core_0.85.4 for a 
         technical description of the change.

- fix incorrect handling of last corrupted segment of a file if it follows a
  corrupted segment.

NOTE: GUI working with earlier version of DCTC still will work but will not be
      able to use the new feature

- .met parameters are returned by /VAR command.

- Handle correctly share list of users having a slash in their nickname.

- Don't allow a delay of 0 minutes with /GDLMETPOLL. 10 minutes is automatically
  used in such case.

--------------------------------------------------------------------------------
* 2003/06/01:
  -----------

- Version 0.85.3

- fix the unfairness of upload/download speed limit. In previous version, most 
  of the time, a transfer obtains nearly all the bandwidth available.

- client can establish connection through web proxy.

- new flag added: -C. This flag is used to provide the address and port of the
  web proxy to use.

- fix a bug crashing the client if it uses glib2.x (glib1.2 version is not
  affected).

- fix GDL type detection problem preventing attachment of broken GDL.

- .sub added to file type "doc" (most of the time, these files contains
  subtitles).

- remove numerous old debug messages.

- 2 new commands added: /GDLMETDIR and /GDLMETPOLL. Using them, DCTC can use
  some informations obtained by the e-donkey emule client (partial CRC in .met
  files).

--------------------------------------------------------------------------------
* 2003/05/04:
  -----------

- Version 0.85.2

- .iso, .bin, .cue and .img added to the file type "exe".

- fix a bug occuring when a broken GDL with L0CRC is available.

- fix a bug occuring when attaching a broken GDL with L0CRC (L0CRC was lost).

- new flag added: -m . If this option is set, DCTC will automatically append a
  dc++ like tag to your description.

- fix a configuration problem when detecting MD* functions.

- fix a hanging problem occuring when an UI disconnects when DCTC sends lot of
  messages to it.

- UADDR handles smarter incoming IP without known name. It prevents duplicated
  IP with IP with known name. To increase efficiency, it also tries a set of
  well known ports accepting DC connection.

--------------------------------------------------------------------------------
* 2003/03/30:
  -----------

- Version 0.85.1

- the old md5 support was removed (option: -5).

- hublist handles an environment variable named "HUBLIST". In this variable, you
  can put all the hublist URL you want to use, use [tab] as separator. If the
  variable is not defined, the default direct connect hublist is used.

- hublist supports bzip2 list.

- fix typo in dctc man pages. Add man page for hublist.

- timeout added to hublist to prevent long wait when a hublist server does not
  respond.

- new program added: dctc_gdl123. This program takes 2 corrupted GDLs of the
  same files and rebuild a partial GDL containing only identical parts of the 2 
  corrupted GDLs.

--------------------------------------------------------------------------------
* 2003/03/09:
  -----------

- Version 0.85.0

- periodically send something to the hub is no network activity exists. This is
  required else the hub will close the connection.

- new command added: /GDLCRC, /GDLNOCRC. Using them, you can set a CRC on a GDL.
  DCTC computes CRC in the same manner has e-donkey 2000 does thus you can use
  its CRC (a 32 characters string composed of 0,1,...9,A,...,F values). The CRC
  allows detection of corrupted file but it does not provide corrupted data
  recovery. (see Documentation/DCextension/ed2k_crc file). 

- minor change in the GLSTC format. To keep compatibility with gtk 1.2 version,
  no field is added. If a GDL CRC exists, it is appended to the script to start
  field, you will see a " &CRC:" field inside it.

- new flag added: -Z. When used, the given parameter is a directory that will
  be used instead of the default $(HOME)/.dctc directory.
  Patch by Henrique do N. Angelo (phpDC project).

- fix g_string_sprintf[a] compilation problem with glib2.

- flag -m is removed. DCTC now always works in extended mode.

- Add support of DC protocol extension commands: MD4Get0 and MD4Set. When 
  connected to a compatible hub, you can send or retrieve partial CRC allowing
  detection of corruption of part of files. (see Documentation/DCextension/
  ed2k_crc file).

WARNING: the CRC computation has 2 effects:
--------
      1) If someone asks your client a CRC of a file you have not yet computed,
         DCTC will freeze during the computation (problem will be solved in
         future release). The computation of the CRC of 450MB file tooks 
         approximately 15 seconds on my XP1700+.
         Note: only the main thread will be busy, download/upload won't be 
         stopped.
      2) the speed of CRC computation and of the splitting of the faulty file
         is done at full speed thus you will have a lot of disk I/O. If you 
         burn a CD on a non burn-proof CD writer, the burning process will
         probably be interrupted. On my test computer (athlon XP1700+, 768MB
         RAM, UDMA100 7200rpm disk), when reparing a 450MB file, I have
         encountered a freeze of 0.5 second due to the high I/O load.

- '*.mid' files are known recognized as audio file.

--------------------------------------------------------------------------------
* 2003/01/26:
  -----------

- Version 0.84.1

- Malformed $MyINFO string is handled more gracefully. DCTC will try to decode
  it to extract valid user information.

- Fix compatibility problem with glib2 (g_strsplit works a bit differently).

- Always reply to transfer request even if no slot is available. This avoid to
  be kicked by hub script (Thanks to Tobias).

- new RPM spec file compatible with more distributions by Mark Schreiber

- the lack of MSG_NOSIGNAL is automatically handled.

- add manual page for dctc_cmd

- Fix some functions to work fine on SPARC platforms (tested on AURORA 1.0)
  (Thanks to Yves BLUSSEAU).

--------------------------------------------------------------------------------
* 2003/01/12:
  -----------

- Version 0.84.0

- SIGCHLD is now ignored to prevent zombi creation (at end of script for
  example).

- fix a bug in GDL renaming function. If the "move into done/ directory" was
  set, the done/ directory does not exist and a new filename like "./filename"
  is used, the downloaded file is not move into the done/ directory and keeps
  its old name.

- new command added: /KICK. This command allows user kicking.

--------------------------------------------------------------------------------
* 2002/12/08:
  -----------

- Version 0.83.9

- obtaining the default IP requires 1 process less than before.

- default IP obtention now supports both previous method (5 process) and BSD
  method (2 process). Based on BSD port patches sent by Thomas Klausner.

- new flag added: min_delay_between_search. This flag allows limitation of the
  number of search queries by setting a minimum duration between 2 searchs. If
  a query comes too close to the previous one, it is silently discarded. Default
  flag value is 0 (no delay).

--------------------------------------------------------------------------------
* 2002/11/11:
  -----------

- Version 0.83.8

- fix a compilation problem in userinfo.c due to a code which cannot be handled
  by all compiler (gcc3.x does, gcc2.x does not).

- fix the compilation problem with Berkeley DB4. (open function of db4.0 has the
  same prototype as DB3 one but db4.1 does not).

- handle more gracefully malformed MyINFO data.

- fix an upload problem occuring when a user having the IGNORE_SLOT_LIMIT flag
  set and being in active mode tries to start a download. In such case,
  previously, the query is ignored.

- new program added: dctc_cmd. This program sends a command to a running client.
  It can be used from script. It takes 2 parameters, the UDP socket of the DCTC
  to contact (files named $HOME/.dctc/running/*.udp) and the command to send
  (see Documentation/commands).

- New flag for user: IGNORE_PUBMSG. When this flag is set, public messages from
  a user can be ignored. Even virtual user can be flagged.

--------------------------------------------------------------------------------
* 2002/11/03:
  -----------

- Version 0.83.7

- fix compilation problem with Berkeley DB 4 (open function has a different 
  prototype).

- man page updated.

- new commands added: /GDLSCRIPT, /GDLNOSCRIPT. Using them, you can add a script
  or a program to start when a GDL is downloaded.

- new file added for running client: $HOME/.dctc/running/dctc-XXX.userinfo
  This file contains the list of all users currently on the hub XXX with their
  description.

- hublist updated to retrieve list of hubs from both neo-modus and dc++.

--------------------------------------------------------------------------------
* 2002/10/20:
  -----------

- Version 0.83.6

- fix a typo error in the LS_cache file of the documentation.

- fix Berkeley DB detection problem for NetBSD. Patch by Thomas Klausner.

- new command added: /GDLASPORTS. This command sets the range of ports to use 
  for autoscan. Note: if the range is too small, not all autoscans will run.

--------------------------------------------------------------------------------
* 2002/09/28:
  -----------

- Version 0.83.5

- a special hub address is recognized "dummy_client". When this name is used
  with the -g option, it is possible to start a client connected to no hub.

- When the dynamic IP flag is set, the IP is updated each time the /RECON
  command is processed whatever the /RECON is successful or not (previous, only
  a successful /RECON update the IP).

- When the dynamic IP flag is set, the IP is updated every minute.

- to ease port, stdout G_LOCK is now named std_out G_LOCK.

--------------------------------------------------------------------------------
* 2002/09/22:
  -----------

- Version 0.83.4

- a (new) buggy clone seems to send string containing illegal character ('\0').
  Because this character is also the C string end character, it truncates string
  and DCTC crashs because an impossible case occurs. This version avoids the
  problem.

--------------------------------------------------------------------------------
* 2002/08/25:
  -----------

- Version 0.83.3

- Dutch Translation of documentation files updated by Myckel Habets.

- DCTC can now use either SOCKS v4 or SOCKS v5 (with or without
  authentification). Currently, usage of SOCKS proxy requires passive mode.
  2 new flags added: -X to enable v5 (default is v4) and -K to provide a 
  password for the SOCKS proxy (if required).

- "fail to rename" error fixed.

- dctc.spec added. It is now possible to build a rpm source archive from the
  tarball with: rpm -ts dctc-x.xx.x.tar.gz

--------------------------------------------------------------------------------
* 2002/07/28:
  -----------

- Version 0.83.2

- Dutch Translation of all documentation files by Myckel Habets.

- /VSHARE command can be used without parameter to remove the virtual share
  directory. The command usage is now in the documentation.

- New command added: /MAXUDL. This command sets the maximum number of
  simultaneous downloads from a user.

- /LS was modified. It returns user share list using a file (new message added:
  LSCCH) instead of sending it using pipe to client (FLST* are deprecated now).
  The share list is kept in a directory used as cache. Note: To reduce size of
  share list on disk, it can be dynamically compressed (if zlib is installed on
  your system).

--------------------------------------------------------------------------------
* 2002/06/15:
  -----------

- Version 0.83.1

- The patch designed to reduce the number of fragments seems to have some side
  effects and breaks most of GDL download. It is temporarily removed.

--------------------------------------------------------------------------------
* 2002/06/09:
  -----------

- Version 0.83.0

- Remove a debug message in the UNODE code.

- To reduce the number of small fragments, when a GDL source starts and the
  previous fragment isn't changing, DCTC simply append new data at this file.
  Patch by Christian Koenig.

- This version supports to be compiled against the new glib2. Add the flag
  --enable-glib2 as configure option.

- ForcejoinGDL.pl is gone and replaced by Tobias' new script: GDL joiner


--------------------------------------------------------------------------------
* 2002/05/26:
  -----------

- Version 0.82.0

- UNODE no more uses berkeley DB because it creates more problems than it solves

- UNODE now uses TCP instead of UDP to reach other UNODE thus no packet will be
  lost, even under very heavy load.

- bug fix in /GDLRENAME and /GDLNORENAME.

- GLSTC message has been modified to include file renaming information.

- TOS support added by Christian Koenig.

- New command added: /TOS. This command permits changes of TOS on the fly.

--------------------------------------------------------------------------------
* 2002/05/12:
  -----------

- Version 0.81.0

- Dutch Translation of VAR and UNODE files by Myckel Habets.

- New flag added: dynamic_ip. If this flag is set (using /DFLAG), before
  connecting a hub, the client recomputes its local IP. It is useful if you
  can have IP changes while client runs.

- INSTALL file updated. ADSL/Cable users should read the changes, this may
  greatly help them.

- new commands added: /GDLRENAME and /GLDNORENAME. These commands allow a GDL
  downloaded file to be renamed and/or move into another directory.

- Fix a possible bug in /LS.

--------------------------------------------------------------------------------
* 2002/05/05:
  -----------

- Version 0.80.5

- A Perl script providing manual reconstruction of file from GDL fragments has
  been added, thanks to Tobias.

- When a GDL ends, if it contains only 1 fragment, instead of copy it into its
  final destination, the client first tries to move it.

- configure can now detect Berkeley DB installed with library following the
  debian naming convention.

- Some code cleaning. Unused /DL code has been removed.

- When a GDL ends and its directory is deleted, previous versions keep a file
  descriptor on this deleted directory.

- Global status file now includes the number of uploads running on each client.

--------------------------------------------------------------------------------
* 2002/04/21:
  -----------

- Version 0.80.0

- Clients now share their upload slot all together, each client no more has its
  own. Note: the "enable uploads" flag remains inside each client.

- UADDR no more uses Berkeley DB because too many problem occurs, especially
  when a client crashs.

- When creating Berkeley DB environment, previous versions use INIT_CDB instead
  of INIT_LOCK and sometimes (too many times in my opinion), this corrupt the
  database (uaddr_ready and uaddr_partial are most of the time affected).

- After a remote user retrieved your share list, the connection is left opened
  during at most 15 minutes.

- Dutch translation of the VSHARE documentation added by Myckel Habets.

--------------------------------------------------------------------------------
* 2002/04/14:
  -----------

- Version 0.79.0

- UADDR functions have been totally rewritten and now uses the Berkeley DB.
  NOTE: when you will switch to this version, the previous content of the UADDR
        base is not imported. DCTC will build a new one and during some minutes
        the direct download will not be able to start transfer.

- the "hide absolute path" flag is now enabled by default. There is too many
  problem when it is not.

- /DL is now a wrapper to /GDL* functions

- the global status file includes a new option telling which DCTC client is the
  master one (== the one updating UADDR list and managing the UNODE).

- GLSTC message includes enough information to compute a more accurate transfer
  speed.

- Fix a bug occuring when a partial file is attached to a GDL. If all segments
  that can be downloaded from this partial file have already been downloaded,
  earliest versions don't stop to try to use this source.

- New command added: /DFLAG. This command goal is to avoid creation of one 
  command for each existing flag. List of flags compatible with this command is
  in Documentation/VAR (D column).

- 2 new flags added: with_incoming_wake_up and with_sr_wake_up. The first one
  wakes up waiting GDL source when a user with the same nickname comes into the
  hub. The second flag does the same action when a search result matching the
  nickname reports free download slot.

- 1 new flag added: min_gdl_wake_up_delay. It is the delay in seconds between
  automatic wake up of waiting tasks of a same user (events: look previous
  flags).

- Thanks to Aubin Paul, DCTC now has a man page.

- New command added: /VSHARE. Using this command you can add virtual share files
  (see Docs/Vshare).

- New command line option added: -D. Same as /VSHARE.

- Fix the bug preventing to share files not located in sub-directory.

- New command added: /LOCATEUSER. This command displays all hubs where the
  given user is connected.

--------------------------------------------------------------------------------
* 2002/04/07:
  -----------

- Version 0.78.0

- configure is now able to guess Berkeley DB version and adapts itself to find
  a valid combination of include/library (v3.x and v4.x). The old detection
  method is still available using --enable-manual-db-detect flag. Usage of
  --with-db option is still required if the include and lib directories are 
  installed in an unusual place.

- 2 new commands added: /LAZYKC and /NOLAZYKC. These commands enable/disable
  lazy key check. Some buggy clients generate a transfer key which is nearly
  good. If lazy key check is enabled, the key is assumed to be ok but only if
  the client which wants to download is yours, not the remote one... who cares 
  about users having a buggy client...

- When a transfer of a GDL source ends and the client is not able to link it
  with another one, the client now wakes up all GDL source having the nickname
  as the ending one. 

- In $ConnectToMe handling function, the buggy "unable to contact" error message
  no more displays junk characters.

- This version biggest new feature is probably the UNODE. The goal of the unode
  is to share the UADDR base (the one used by direct download to be able to 
  download without hub connection) and to relay search queries on more than one
  computer. Let's assume you have 2 friends running DCTC and connected on hubs
  you never go. Using this feature, you are able to find files owned by users
  currently on hub where your friends are, you can even do search as if you were
  connected on this hub.

- Add new flag in the user flag list: IGNORE_SLOT_LIMIT. When a user has this
  flag, it can always start a download, even if no download slot is available.

- Fix a bug in the /SHARE command. If the given directory ends with a '/', this
  slash is discarded. Previous version keeps it and it creates entry with '//' 
  in the shared file list and unfortunatelly, remote users cannot download files
  having this '//'.

- Fix a bug in download function when you have direct download enabled. If you
  download from someone having its address in the UADDR cache, if this user IP
  changes and he comes back on a hub where you are, earlier versions of DCTC
  still use the IP in UADDR until the UADDR entry expires (can take up to 12
  hours). Most of the time, the bug does not appear because the user with its
  new IP has made some search queries and DCTC has seen him. With this new
  version, even if the user does nothing, DCTC will be able to find its new IP.

- Fix a bug in search result string. The reply now includes the hub port.

--------------------------------------------------------------------------------
* 2002/03/30:
  -----------

- Version 0.77.0

- Spanish translation of INSTALL and README files by Iigo Lpez-Barranco Muiz.

- When the client was disconnected from the hub, the previous version forgets to
  load the previous client status before modifying it.

- Error returned by Berkeley database is handled more gracefully.

- 2 new commands added: /DBL and /GBL. /DBL is like /UBL but for download
  instead of upload and use bloc of 1KBytes instead of 512bytes one. /GBL allows
  a limitation of the number of 8KBytes blocs copied per second when a client
  gather all parts of GDLs.

- Support of Berkeley Database 4.0 added.

- The configure script now has the option --with-db to specify where the
  Berkeley Database include and lib directories are. If you have compiled the
  library yourself, you probably will have to use this option with something 
  like /usr/local/BerkeleyDB.4.0 as parameter.

- -u flag takes now 3 parameters instead of 1.

--------------------------------------------------------------------------------
* 2002/03/24:
  -----------

- Version 0.76.0

- Dutch translation of the GDL and BerkeleyDB documentations added by Myckel
  Habets.

- Fix a severe security bug in the function handling download. Due to a missing
  character in the C code, it is possible to download any file, shared or not
  as long as you know its name. Problem notified by Morra.

- When the client was disconnected from the hub, the previous version resets the
  number of GDL of the global status file. The problem has been fixed.

- new commands added: /HIDE_KICK, /SHOW_KICK. Enable/disable hub-security global
  chat kick message deletion. To limit pollution of global chat, I suggest you
  to discard these annoying messages.

- An UI can now send DCTC commands in client udp socket used by DCTC link.

- minor error message fixed in berkeley database initialization. DCTC should no
  more crash when database creation fails.

--------------------------------------------------------------------------------
* 2002/03/17:
  -----------

- Version 0.75.0

- The user informations are now sent to the server only if they differ from the
  previously sent ones. This will avoid to periodically receive the incoming
  message from buggy hub bots.

- BerkeleyDB v3 library/includes is required.

- remote users can now be "flagged". The following flags are available: ignore
  private messages, ignore search queries, ignore search_replies.

- new extra command support added: $ChgSSP. This command is a sub-command that 
  can be used during a transfer. Command added by Yves Blusseau.

--------------------------------------------------------------------------------
* 2002/03/10:
  -----------

- Version 0.74.0

- The value given by /GDLASOFFAFT is now properly taken into account to limit
  autoscan. Previously, the /MAXRUNGDLSRC value was used instead.

- when a private message is relayed to other running DCTC clients thru DCTC
  links, the hubname is included in the relayed message.

- web proxy support added to hublist. Patch by Thomas Stewart.

- To avoid wasting bandwidth, download queries received when no download slot is
  available are discarded without even starting a transfer handshake.

- global status file now includes the number of GDLs and the number of users of
  each running client.

NOTE: BerkeleyDB library/includes will be needed by the next version.

--------------------------------------------------------------------------------
* 2002/03/03:
  -----------

- Version 0.73.0

- nickname bug fixed in "Null download connection" message.

- fix a bug in the Makefile.am. hublist is now properly linked with glib.

- /SLOWGDLLST delay has been changed from 8 to 4 seconds.

- New commands added: /HIDE_ABS, /SHOW_ABS. This will hide/show the first 
  character (/) at the beginning of the directory you share.

- Polish Translation of installation and readme files by
  Piotr '_PepeR_' Wojciechowski.

- Before using .dctc or .dctc/running directories, DCTC now first check if it
  can access to them.

- New commands added: /ABORTLEAVED, /NOABORTLEAVED. Cancel uploads of users
  having left the hub.

- New command added: /MAXRUNGDLSRC. This command adjusts the limit of number of
  simultaneous running download source per GDL.

- New command added: /GDLASOFFAFT. If the number of running sources of a GDL
  reachs the given number, autoscans of this GDL are disabled.

--------------------------------------------------------------------------------
* 2002/02/24:
  -----------

- Version 0.72.0

- file type has been updated.

- new file added: $HOME/.dctc/gstatus. This file contains the status of all
  running DCTC client (online, offline).

- new command added: /SLOWGDLLST. It is a limited version of /GDLLST taking 
  the command into account only if it has not be entered in the last 8 seconds
  (useful to limit dialog between UI and DCTC).

--------------------------------------------------------------------------------
* 2002/02/16:
  -----------

- Version 0.71.1

- fix the segmentation fault problem occuring when a relayed private chat
  message is a multiline message and starts with newline(s).

--------------------------------------------------------------------------------
* 2002/02/16:
  -----------

- Version 0.71.0

- fix the bug occuring when a multiline string is pasted into the private chat.
  Previously, the destination user received it but the local user sees nothing.

- Away status is now taken into account when creating a new client.

- Indirect private chat is now supported. If dctc link is enabled, you can
  dialog with any user from any hub you are connected using any of the running
  DCTC. Using this feature, you can centralize all chats into one GUI or jump
  from one DCTC to another without interrupting chats.

- new commands added: /DLFORCE, /NODLFORCE. Force your download to start with a
  remote client even if the remote client wants to download.

- new command line option added to configure script. --enable-bug-workaround.
  On some old glibc, some bugs occurs when some functions are called from thread
  mainly if the CPU is not able to perform unaligned memory access. The problem
  has been noticed with a SPARC CPU running redhat 6.2 and during a semctl
  (GETVAL) call. Using this option installs a workaround these bugs.
  
--------------------------------------------------------------------------------
* 2002/02/09:
  -----------

- Version 0.70.0

- /LS is now able to use direct download.

- GDL autoscan can now use dctc link.

- when attaching a GDL to a running client, autoscans of the attached GDL now
  restarts.

- search results no more display the client own files. Previously, the client
  displays your own files if they match the query.

- minimal length of remote search query has been modified. It is now a 2 char
  pattern (previously, it was 4).

- random number generator is now properly initialized.

- when moving to another hub, being disconnected, ..., the nickname is resetted
  to its original value, any digits appended to avoid nickname conflicts are
  discarded.

- /LS command is now only started by client having either a console display or
  a local UI connected. This avoids the problem of having a client without
  display starting a /LS (created by another client) just because direct
  download is enabled and it has the remote user address.

- In few cases, DCTC can now links GDL downloads (like normal download does).
  You won't have to wait a long time for a free slot.

- hublist and DCTC now support SOCKS proxy (version 4 only). New flags added in
  DCTC (-S, -P, -U). hublist accepts 2 or 3 parameters (socks proxy address,
  port and user ID (if necessary)). SOCKS support is in its early stage,
  sometimes, returned error messages may have no meaning.

--------------------------------------------------------------------------------
* 2002/02/03:
  -----------

- Version 0.69.0

- when /GDLEND is used, the killed GDL's download directory is now properly
  destroyed.

- Fix the "long try" GDL problem. Sometimes, starting GDL transfer fails and
  remains in try mode for a long time (it wastes no CPU or bandwidth, it just
  waits the timeout to retry).

- Dutch Translation of installation and readme files by Myckel Habets.

- new flag added: --dctclink. Enable the capability to cooperate with other
  running DCTC client to perform some task like /SRCH, /DL and GDL download
  on all connected hubs at the same time.

- new commands added: /LINK, /NOLINK. Enable/disable dctc link (see --dctclink)

- Fix the GDL direct download bug. Previously, direct download is not used by 
  GDL even if the option is enabled.

--------------------------------------------------------------------------------
* 2002/01/27:
  -----------

- Version 0.68.0

- New command added in client to client protocol: $GetFileLength.

- In active mode, each GDL can now scan for new download source using one or 
  more search patterns (autoscan).

- New GDL commands added: /GDLAS+ (add autoscan pattern), /GDLAS- (remove auto
  scan pattern), /GDLDETACH (detach a GDL of the client).

- fix a crash occuring when the local client wants to start a download and 
  when simultaneously, the remote client connection ends before remote client
  direction has been received.

- several memory allocation errors have been fixed.

- bzip2 has been added to the list of compressed file type.

- fix a crash occuring when the client creates a new transfer thread and 
  pthread_create return EINTR. I am not sure the problem still occurs with 
  glibc 2.2 but it exists with glibc 2.1. Previously, the client supposes the
  thread does not exist and frees its memory -> core dump. Now, the client
  supposes the thread exists. In the worst case, few memory is lost but it no
  more coredumps.

- to reduce CPU load, GTS is now called only every 5 seconds. With the DDL
  support and without this limit, we can easily achieve a 100% CPU load,
  especially with a lot of running connections.

--------------------------------------------------------------------------------
* 2002/01/20:
  -----------

- Version 0.67.0

- DCTC now enables the "SERVER" status if the client is up for more than 2 hours
  and shares more than 2GB (including offset).

- Pong command is now supported.

- --nomd5sum bug has been fixed (-5 flag is not affected).

- new feature added: DDL (Direct download). Using this, it is possible start a
  download without being connected to a hub (remote user must be active, not
  passive) or even having one running dctc connected to a hub (using GTS, it is
  only possible to have xfers moving from one client to another but only if the
  destination client is connected). This feature affects both the normal
  download (/DL) and GDL download (/GDL).

- new commands added: /DDL, /NODDL. Enable/disable download without hub.

- On hub connection loss, DCTC sends new connection status to UI.

- Fix the bug preventing user to enter a hub as registered user if DCTC has been
  launched from UI.

- GLSTC message has been modified to include GDL start time and download bytes.

--------------------------------------------------------------------------------
* 2002/01/13:
  -----------

- Version 0.66.0

- In GDL, DCTC no more crashs on do_gdl_start when no download range can be
  allocated.

- Fix the Glib-CRITICAL message occuring when no data are received during
  transfer handshake.

- Fix the crash occuring when during transfer handshake, the connection is
  closed just when a $Lock is expected.

- Some info messages are now debug messages.

- minor communication code parts have been changed to reduce unwanted signal
  generation.

- new flag added: --nomd5sum. The MD5sum is used for content search. If you run
  DCTC on a slow computer or share a lot of file (in number, not in size), MD5
  computation can take a long time. Using this flag, you can disable it.
  Note: once disabled, it is not possible to reenable it without leaving the 
  client.

- when attaching a GDL to a client, the client now immediatly checks if the GDL
  is completed.

--------------------------------------------------------------------------------
* 2002/01/06:
  -----------

- Version 0.65.0

- Fix the bug preventing /GDLEND to work properly on a running and not finished
  GDL.

- Fix a bug in the users information caching system.

- Fix the bug crashing DCTC when creating semaphores on some OS (redhat 6.2 on
  sparc for example).

- DCTC now handles nickname conflict properly.

- a REFRESH_MSG is now sent when a task is removed from the running task list
  due to a timeout on start.

- an error message is now displayed for each file not taken into account in the
  shared directories.

- fix forever trying GDL tasks. In fact, only their status is trying but they
  don't really try.

- when a GDL ends, its temporary directory is now cleared and destroyed.

- GDL now properly supports the when_done flag (move complete file into the
  done/ directory).

- When a GDL ends successfully, the result is stored inside the .done file, 
  as standard download does.

- To avoid multiple client to download the same GDL file, a lock is now set in
  the GDL file temp directory.

- To allow GDL resuming, inside a GDL file temp directory, a description of the
  running GDL is saved inside this directory.

- To allow GDL resuming, new command added: /GDLATTACH. Use it followed by the
  name of the GDL you want to start. If it exists and is still not busy, it is
  load in the current client.

- when trying to leave DCTC with /FORCEQUIT, running connections are now closed.
  Previously, uploading threads may remain alive and uploads.

- GDL sources are only used if the user having the source nickname is on the hub
  (it is stupid to waste bandwidth sending requests which cannot success).

- GDL download range now takes into account the remote file size of this
  connection. Previously, it is ok when a download is started but during the
  transfer, this information is not taken into account.

- Fix a bug in initial download range allocation function occuring when there is
  no unused segment.

- it is now possible to give an empty password to /PASSWD. Just use "/PASSWD ".

- DCTC now handles hub redirection. It can either disconnect and come back
  later or follow the redirection.

- 2 new commands added: /FOLLOW_FORCE and /UNFOLLOW_FORCE.
  
- DCTC now supports OS without mmap.

- A display bug forcing DCTC to pause forever has been fixed.

- It is now possible to send multi-line message in the chat (/CHAT) and in
  private chat (/PRIV) using \r where new line must be inserted.

--------------------------------------------------------------------------------
* 2001/12/30:
  -----------

- Version 0.64.0

- To avoid unnecessary DC commands, Users information (/UINFO result) is now
  cached.

- New output message type added: "PRGBR]". This message appears to report
  progress of a task. Currently, initial shared file database building uses it.

- client to client transfer function has been partially rewritten to be more 
  efficient and accurate. 

- For future usage, in the client to client transfer, a new command has been
  added ($Capabilities) which describes which enhanced function the client
  support (see Documentation/DCextensions/p2p_cabilities for more information).
  The client remains compatible with DC.

- previous version of DCTC doesn't return anything when the searched pattern is
  at the end of the matching string. Bug is now fixed.

- For user in active mode, in earlier version, an error can occur when creating
  communication port. If the search port fails to create, active search fails
  until the /PORT command is used. The problem has been fixed both when starting
  DCTC and when performing a /PORT.

- search pattern handling works now in the same manner has DC does. Use $ to
  separate searched strings.

- it is now possible to download one file from multiple source at the same time
  using a segmented download. This feature is in ALPHA VERSION. (see /GDL* and
  Documentation/GDL for more information)

--------------------------------------------------------------------------------
* 2001/12/23:
  -----------

- Version 0.63.0

- some remote users extra information are now guessed. DCTC can identify users
  running in passive mode. It can also still find host address/port of active
  mode users. This is the first step of the hubless download. Using these
  information it is technically possible to start download without being
  connected to a hub.

- minor error fixed in $Capabilities function. Reply can be sent on the wrong
  socket.

- new command added: /RECOND. Using it, you can change the hub reconnection
  delay when the client loses the hub connection.

- new flag added: --precmd. The parameter of this flag is a / command. All the
  commands given using one or more this flag are performed before the hub
  connection. See Documentation/commands for more information.

--------------------------------------------------------------------------------
* 2001/12/09:
  -----------

- Version 0.62.0

- DCTC now uses automake/autoconf. Just compile with ./configure ...

- hub address (-g option) can now contain a port. Syntax: hubaddr[:hubport]. If
  no port is given, the default one is used.

- Despite a bug fixed in the previous version, DCTC still crashs. Another bug
  has been found inside transfer initialization. When the transfer is initiated
  by the remote side, if during this initialization, the remote side closes its
  connection before sending a direction, previous DCTC versions crashed. The
  problem should be fixed now.

- new option added: --mdc. Its default value is 0 (DC compatible command).
  If the value is set to 1 and a compatible hub is found (none still exists),
  DCTC uses an extended command set. Currently, only extra command is supported:
  $Capabilities (see Documentation/MDC for more information).

- new message added: $ULST]. For each running upload, this message contains the
  upload status.

- new command added: /RESHARE. Rebuild the database of shared files to take into
  acount added/removed files/directories.

- new command added: /REUINFO. resent user information to the hub (mainly used
  internally).

- The shared file database is now rebuilt every 15 minutes.

--------------------------------------------------------------------------------
* 2001/12/02:
  -----------

- Version 0.61

- The bug preventing some clients to perform download from a DCTC client. The
  problem seems to occur only with old glibc but not with recent one. A
  misplaced MSG_WAITALL on send system calls was the problem. Newest glibc
  doesn't care about this unuseful flag but oldest seems to.

- To work like DC, now, no more than 5 search results are sent to each search
  query.

- Trying to fix the bug randomly crashing DCTC. It is quite hard because the
  problem occurs very randomly and everytime, the stack is trashed.

- To improve bandwidth usage, when /ULIST is entered, if DCTC already has the
  user list, it doesn't retrieve it one more time but use the one it has.
  To avoid any potential problem, the command /ULIST_FORCE has been added and
  force DCTC to retrieve user list from the hub, even if it still has it.

- -s option has been rewritten. Shared directories are now added after the un*x
  socket has been created. Thus, UI should no more think the client has hanged
  because it doesn't respond for a too long time.

--------------------------------------------------------------------------------
* 2001/11/24:
  -----------

- Version 0.60

- the client now can link downloads (file or file list) on the same connection.
  It no more releases the download connection and tries to establish a new one.

- upload bandwidth limitation added. The bandwidth is set for all clients 
  running on the same computer and having the same owner. This bandwidth is
  shared by them.

- -u added to set up the default bandwidth limit.

- /UBL added to dynamically change the bandwidth limit of running clients.

- When changing the number of upload slots, the number of free upload slots is
  now properly adjusted.

- minor bugs occuring when an upload tries to start and all upload slots are
  busy have been fixed. Previously, a 10 bytes string is sent to the client
  which though it is 10 bytes of the wanted data while it is the error message.

- same problem as previous one fixed for the shared list download.

--------------------------------------------------------------------------------
* 2001/11/06:
  -----------

- Version 0.59

- Password protected nickname are now supported (see /PASSWD command and 
  PASWD] message).

- Fix a minor bug occuring sometimes when a UI reconnects a running client.

- Sometimes, the last displayed (or sent to local socks) messages are lost.
  The problem should be fixed now.

--------------------------------------------------------------------------------
* 2001/10/21:
  -----------

- Version 0.58

- it is now possible, with compatible client (DCTC, ...), to search file by
  content instead of filename.

- After 5 minutes, the client automatically switches on the away flag.
  Side effect: this action also keeps the connection alive. Since v0.56, the
  download function has been optimized to reduce bandwidth usage but due to this
  optimization, the command connection can remain unused for a long time so the
  hub disconnect the client. Because the client has no more things to send, it
  does not establish a new connection to the hub.

--------------------------------------------------------------------------------
* 2001/10/07:
  -----------

- Version 0.57

- fix the compilation problem occuring on some linux distribution in db.c and
  also some warnings.
  
- new flag added: -v. This flag allows you to override protocol version sent by
  DCTC to hubs. Thus, it is no more necessary to wait new release of DCTC to
  enter hubs only accepting latest DC client.

- current DC protocol version has changed from 1,0009 to 1,0091.

- fix the "crash all running clients" bug. In fact, this bug doesn't crash all
  clients. All clients are crashing when they attempt to lock the .dctc/gts.*
  file at the same time.

- /HUBNAME crash fixed. The first previous changes of the v0.56 has created new
  bugs. For example, if the hub is slow to return its name and someone has
  already entered commands, some commands may crash because there is no valid
  result to return (ex: /HUBNAME). 

- SIGHUP is now catched. If the start shell ends (or crashs), dctc will stay
  alive. This change has been done because the xterm of Mandrake 8.1 seems to be
  buggy and crashs when "strange" strings are displayed.

--------------------------------------------------------------------------------
* 2001/09/30:
  -----------

- Version 0.56

- the keyboard input now is available when the client is trying to establish a
  connection with the hub, even if the hub is very slow to reply.

- the queued download list is now shared by all clients. Thus, transfer can
  move from one hub to another.

- remote search query are now supported if the remote client is in active mode.

- sometimes, the GUI hangs because it waits DCTC and DCTC hangs because it waits
  the GUI. The problem comes from socket capacity. When both programs want to 
  write but nobody reads, the sockets become full and both program wait. The
  problem is not solved but it should be no more occur ... at least until very
  big hub (approximately more than 800 users) exists.

- patch from David Toth: File sharing list Windows (DC) compatibility bugfix.
  The byte 4 of the file list is now computed.

- Protocol violation has been removed when a DC client wants to retrieve the
  shared file list. In combination with the previous patch, the list of shared
  files can now be displayed by Direct Connect.

- To avoid compatibility problem, if path containing shared files are absolute
  (starts with a slash), DCTC transparently replaces it by a  (0xFF). This
  tips is not visible in a search result, only in shared file list.

--------------------------------------------------------------------------------
* 2001/09/22:
  -----------

- Version 0.55

- fix the hanging problem occuring when the client losts its terminal. Previous
  version hangs forever.

- new command added: /DONE and /UNDONE. When a download ends, the file can be
  moved into the done/ directory or stay where it is.

- new flags added: -t and -w. -w = /DONE. if -t is used, the program 
  immediatly closes its input and output descriptor thus no messages are
  displayed on the shell and commands cannot be entered using the keyboard.
  This flag is mainly here to provided a "clean" interface to GUI.

- new flag added: -l. When -l is provided, at the very beginning, the client
  hangs until someone connects to its local socket (like a GUI). This flag is
  only here for GUI.

--------------------------------------------------------------------------------
* 2001/09/15:
  -----------

- Version 0.54

- fix the crash problem occuring when a program disconnect from the local socket.

- in directory $(HOME)/.dctc, a file recent contains the list of all recently
  contacted hubs.

- get_a_dc_line has been updated to avoid hanging when the network connection
  hangs.

- new flag: -x. Same as /DLOFF but from the command line.

- bug fix in the /PORT command. Changing the transfer port on the fly now works.

- bug fix in /VARS. shared dir list is now correctly returned.

- new command added: /LPATH. change the download directory.

- if the transfer port is already used by someone else or cannot be used, the 
  client tries the ports after the given one until it found one.

--------------------------------------------------------------------------------
* 2001/09/09:
  -----------

- Version 0.53

- some no more useful INFO messages have been changed into DEBUG messages. The
  client will be less verbose.

- New command added: /LS. this command retrieves the list of the given user
  shared files.

- New command added: /VARS. the command returns the value of some internal
  client vars.

- Some new output messages have been added: ASTRT,ASTOP, RFRSH, BXFER, VAR.
  Those messages are here to simplify task managment of a GUI.

- When starting a new client, it creates an Unix socket into $(HOME)/.dctc/running.
  socket name is "dctc-xxxxxxxx-yyyy" where xxxxxxxx is the pid of the process (8
  characters) and yyyy is the hub address (the one provided by -g). A file is also
  created with the name "dctc-xxxxxxxx-yyyy.done". It contains the list of all
  done transfers.

- Remote clients can now retrieve the list of files shared by the client. For an
  unknown reason, DC fails to display the file list while this client
  successfully displays it (who cares, only windoz users won't see the file
  list).

- To avoid unwanted termination of the client, some signals are now captured
  (Ctrl-C). Ctrl-C now works only after a /QUIT has been entered.

- New command added: /ERRLOG. Same function as /LOG except only "ERR ]" messages
  are logged. If both /LOG et /ERRLOG are used at the same time,"ERR ]" messages
  are written in both files.

- On download, if the client receives a $Error message, it now aborts and
  reports the error message. Previously, the client retries which is not very
  useful because the $Error message only appears when the wanted file is no more
  available.

- If someone tries to download a file which is no more shared, the client now 
  returns an error message before closing the transfer connection.

- when the client fails to open (err)log file, it now reports the error.

- if no data are shared, the client always returns "no more download slot" to 
  client who want to get your file list.

--------------------------------------------------------------------------------
* 2001/08/24:
  -----------

- Version 0.52

- Fix the thread creation problem. Previously, after many tries (upload/
  download), due to an error, the client cannot create new threads. This case
  mainly appears on heavily loaded hub and/or if you let the client up for a
  quite a long time (more than 12 hours).

- Simultaneous download from the same user is no more possible. In such case,
  1 transfer runs and all others remain queued (in the CMDKB list).

- In some quite rare cases, a just failed download is requeued more than one
  time. To avoid the problem. It is no more possible to queue more than one time
  the same download query.

- Active mode search is now available.

- New command added: /MSEARCH. Using it, you can do a multi-hub search.

- New command added: /HUBNAME. Reprint the name of the current hub.

- The client doesn't crash anymore if, when it tries to reconnect to the hub,
  the hub doesn't send an invalid connection string.

- After using the /DLOFF command, when replying to a search query, the client
  tell all download slots are busy.


--------------------------------------------------------------------------------
* 2001/08/18:
  -----------

- Version 0.51

- Bug fix in download function. If the connection is closed, the thread now
  exits. Previously, the thread eats all CPU inside an infinite loop.

- when a remote client queries a connection from the client, the client no more
  hangs until the end of connection establishment.

- transfers no more hang forever after a network error. A timeout of 10 minutes
  has been added. Due to the fact that Direct Connect works with 8KByte bloc,
  a timeout of less than 8 minutes is not recommended else a timeout may occur
  if speed goes beyond 1KB/s.

- if a download is aborted due to a network error, it is automatically restarted
  30 seconds later. The download always resumes from the end of file.

- if a download is aborted due to the lack of remote client response (ie. user
  has left the hub), the download is automatically retried 1 minute later.

- New message type added: CMDKB. It is a commandline which will be sent
  automatically when the given time is reached.

- New command added: /KILLKB. This command allows you to remove a queued command
  from the CMDKB list.

- New commands added: /LOG and /NOLOG. Using these commands, you can save
  displayed messages into a log file.

- After a hub disconnection, the client will now try to reconnect it every 5
  seconds until you force the client to quit (/QUIT) or the connection can be
  reestablished. During this time, keyboard commands still are available.


--------------------------------------------------------------------------------
* 2001/08/15:
  -----------

- Version 0.50

- Initial public release

- The most useful functions are available and work.

  Missing functions are:
   - file browsing from local and remote host.
   - active mode search. Currently, only passive mode search is available.
     If you are in active mode, the client switched just a few moment into
     passive to perform the search, this doesn't affect any running or incoming
     connection.
   - more accurate upload status. Currently, only the filename is reported.
   - support of operator functions. Currently, only the most useful user
     functions are available.
