UnZip, version 5.52, 28 February 2005

Features added (or removed):

5.52a (10 Dec 04):
 - no new features

5.52b (30 Dec 04):
 - no new features

5.52c (8 Jan 05):
 - no new features

5.52d (17 Jan 05):
 - VMS: Faster I/O, both reading the archive and creating extracted data
    files.  Disk paralysis during file allocation, when highwater marking
    is enabled on the destination device, is gone.  [Steven Schweda (SMS)]
 - VMS: Where the C RTL permits, with SET PROCESS /PARSE = EXTENDED,
    command-line case is preserved, obviating quotation of upper- or
    mixed-case options and parameters.  [SMS]

5.52e (23 Jan 05):
 - i386 ASM_CRC code crc_i386.S, win32/crc_i386.asm, win32/crc_i386.c:
    enabled optimization for i686 by default, as pre-686 CPUs are no longer
    widely used nowadays. (win32/crc_lcc.asm was already i686-optimized)
    [Cosmin Truta (CT)]
 - INSTALL, unzpriv.h: unshrinking is now enabled by default [CT]
 - AtheOS/BeOS/Unix: do not restore SUID/SGID/Tacky bits per default; added
    new security override option "-K" for backward compatibility, updated
    unzip.1 man page [Johnny Lee, EG]

5.52f (27 Jan 05):
 - unzpriv.h, list.c, zipinfo.c: added recognition of additional hosts and
    compression methods according to latest PKWARE appnote specs [SPC]
 - AtheOS/Syllable: new port, kindly contributed by Nikolaev Ruslan [SPC]

5.52g (06 Feb 05):
 - no new features

5.52h (20 Feb 05):
 - no new features

5.52i (24 Feb 05):
 - no new features

5.52j (27 Feb 05):
 - no new features

5.52 (28 Feb 05):
 - no new features

Bugs fixed:

5.52a (10 Dec 04):
 - Debian patch 001 - change __GNU__ to __GLIBC__ in unix/unxcfg.h.  This is
    required to build under glibc-based systems not being Linux-based (like
    the Debian GNU/kFreeBSD port, which is in preparation).  In fact,
    everywhere the macro __GNU__ is used, __GLIBC__ should be used instead.
    It could be made even shorter since defined(linux) || defined(__GLIBC__)
    should be the same as simply defined(__GLIBC__).
 - fileio.c - open_input_file(): added trailing newline to error message
    [Debian patch 002, Santiago Vila]

5.52b (30 Dec 04):
 - README: added short note about purpose of release 5.52 [Ed Gordon]
 - format fixes [Ed Gordon]

5.52c (8 Jan 05):
 - minor fixes [Ed Gordon]

5.52d (17 Jan 05):
 - On VMS, when an odd output byte count is incremented to the next
    larger even value, the extra byte written is now always zero,
    reducing random differences between original and extracted files.  [SMS]
 - On VMS, "cannot find either fred;1 or fred;1.zip." messages have been
    changed to show only non-fictional file names.  [SMS]


5.52e (23 Jan 05):
 - win32/vc6/unzip.dsw (new): replaced win32/VC6.dsp with a complete
    Visual C++ 6.0 project to build unzip, funzip and unzipsfx, with both
    ASM and non-ASM settings  [CT]
 - win32: MSC project files now preserve Win32 CRLF line ends [CT]
 - win32/crc_i386.c: compile only if ASM_CRC is defined [CT]
 - changed strcasecmp to strncasecmp in vms/vmszip.c [SMS]

5.52f (27 Jan 05):
 - win32: for UnZip 5.5x, our tradition "distribute all text files with LF line
    endings" remains in effect, MSC project files are plain text and get
    distributed in UNIX LF-only format [SPC]
 - windll/windll.rc: updated copyright year [SPC]
 - proginfo/extra.fld: synchronized with current appnote.iz (and PKWARE's
    appnote.txt v6.2 as of 2004-04-26) [SPC]
 - win32/makefile.lcc: adapted to current lcc-win32 release [SPC]
 - windll/uzexampl.c: fixed some function definition mismatches (previously
    there were different but compatible param types used) [SPC]
 - extract.c: fixed ucsize/csize mismatch test introduced in UnZip 5.51 and
    corrected a follow-up extraction size bug (12 excess bytes written) for
    encrypted stored entries [SPC]
 - MacOS, OS2 - fixed security holes: formatted output (?printf) should not
    use unchecked strings as format specifiers [Ulf Harnhammar]
 - man/unzip.1, man/zipinfo.1: added explicit note on how to supply a
    left bracket in a filename argument; clarified the scope of the -C option;
    documented the different compressed size calculation modes for encrypted
    entries in UnZip's and ZipInfo's listing output [Greg Roelofs, SPC]
 - list.c, zipinfo.c: fixed ancient bug: when specifying only an exclude list,
    all not-excluded zip archive entries should be listed [SPC]
 - extract.c, unzpriv.h, w32.cfg, wce.cfg: added Cdecl modifier to the qsort
    comparison function (allows use of stdcall mode in SFXWiz project) [SPC]
 - extract.c, unzpriv.h: use LONGINT consistently for >>all<< zipfile offset
    variables and adapt some type casts (allow handling of 4G archives on
    systems that support 64bit file offsets) [Paul Slootman]
 - renamed LONGINT into Z_OFF_T for better "in-code-documentation" [SPC]
 - unzpriv.h, NEXTBYTE macro modified to allow compatibility with unsigned
    bufsize counter incnt [Steven M. Schweda]
 - unix/unxcfg.h: corrected Debian patch #1 by re-adding __GNU__ conditionals
    where they appeared before [SPC]
 - unzip.h, win32/decs.h, win32/struct.h: encapsulated declarations as
    extern "C" for C++ compilation mode [SPC]
 - Win32 port: integrated deferred NTSD handling for directories in the
    generic dir attributes setting functionality [SPC]
 - Win32: synchronized new MSVC6 project files with master Makefile (removed
    unused modules and link libs, SFX opt for size, enable DBCS) [SPC]
 - BeOS: synchronized code with Unix port to support reentrancy [SPC]
 - All but TOPS20, VMS, WinCE: added length check to externally
    supplied argument in do_wild() [SPC]

 - VMS (fileio.c - open_infile()): corrected VMS specific open-args, patch
    was accidentally left out in 5.52f [SMS, SPC]
 - win32/w32cfg.h: define Cdecl as empty macro for Watcom C [P. Kienitz, SPC]
 - win32/win32.c: updated OS-system message in version() [SPC]
 - extract.c: corrected integer size mismatch in deferred dirs code [SPC]
 - VMS: support "-T" option as /TIMESTAMP in CLI command interface [SMC]

    of recently added options and new hint notes [SMC, SPC]
 - win32/win32.c - set_direc_attribs(): work-around for "cannot set timestamp
    of read-only dirs" bug [Cosmin Truta]
 - win32/win32.c - NTQueryVolInfo(): fixed typecast warning [Cosmin Truta]
 - unzpriv.h, unix/Makefile, win32/Makefile.gcc: changed build policy for
    POSIX-emulating gcc distributions on Win32 (e.g. CygWin) to default to
    creating POSIX-mode binaries; win32/Makefile.gcc may be used to build
    win32-aware binaries (added -DFORCE_WIN32_OVER_UNIX to default compilation
    options) [Cosmin Truta, SPC]
 - INSTALL, History.552: stylistic text corrections [Cosmin Truta]
 - win32/win32.c: complete revision of timestamp handling code; added prepro-
    cessor flag NO_W32TIMES_IZFIX to allow optional compile with time handling
    exactly like the (faulty) standard of other Windows programs [SPC]

    option [SPC]

    issues but created new bugs) [SPC]
 - windll/windll.txt: documented the exact meaning of the windll struct DCL
    flags nfflag, ExtractOnlyNewer, noflag, PromptToOverwrite and their
    interactions [SPC]
