library version was considered useful. See the release notes for more
details.

New NSStream classes where added to the library.

filesystem changes in gnustep-make, several components of gnustep-base
are located in different locations. Generally this should not affect the
compilation or running of applications and tools.

@end itemize

@section Noteworthy changes since version @samp{0.1.19}

@itemize @bullet

@item The library has changed its name from @samp{libobjects} to
@samp{libgnustep-base}.  The Apr 17 ChangeLog entry contains a list of
the way various other names were changed.

@item The library now requires a patch to gcc-2.7.2.  The patch adds
thread-safe features to the GNU Objective C runtime.  Each thread has
its own exception handler and assertion handler, thanks to Yoo C. Chung
@email{wacko@@power1.snu.ac.kr}.

@item Distributed Objects is much improved.  Exceptions in the server
are sent back to the client.  Ungracefully closed connections are
gracefully handled.

@item NSUserDefaults has been implemented, thanks to Georg Tuparev
@email{tuparev@@NMR.EMBL-Heidelberg.DE}.

@item NSScanner has been implemented, thanks to Eric Norum
@email{Eric.Norum@@usask.ca}.

@item NSCharacterSet has a new caching scheme, and is now faster than
NeXT's implementation, thanks to Adam Fedor.

@item Preliminary thread-safety work has been done.  NSObject and
NSAutoreleasePool should be thread-safe.

@item The "%@@" printf directive now works on systems without GNU libc.

@item The NS*Page* functions have been implemented.

@item The mframe and behavior functions have been overhauled and
better commented.

@item The NSHashTable and NSMapTable functions have been implemented,
thanks to Albin Jones @email{albin.jones@@dartmouth.edu}.  Albin has also
implemented underlying GNU functions that provide functions for arrays
and linked lists of C-type variables.

@item The NSThread class has been implemented.  Thanks to Scott
Christley @email{scottc@@net-community.com}, the NSLock class has been
implemented.

@item A RunLoop class has been implemented, and is used for listening to
Port objects.  It is used for Distributed Objects.  There is also an
NSRunLoop class based on RunLoop.

@item The NSTimer class has been implemented, although its use with
RunLoops is currently disabled.

@item The Notification mechanism has been implemented.  It makes good
use of hash tables and linked lists in order to be fast.

@item The Invocation class heirarchy has been fleshed out and now
works. 

@item The collection classes have been overhauled to better handle
distributed objects, and for better compatibility with NeXT's method
names.  

A new separation has been made in the abstract collection
classes: IndexedCollections contain objects accessible by an integer
key, but the user cannot insert at an arbitrary key; these are useful
for sorted collections, such as SplayTree's. OrderedCollection can have
their order determined by the user; i.e. users can send
@samp{-insertObject:atIndex:}, etc.

There is a new set of rich enumeration methods based on Invocations.

@item Port class heirarchy has been overhauled.  There are now classes
for TCP ports, UDP ports, and Mach ports.  Only the TCP ports are
currently functional.

@item GNU-style archiving has had an overhaul, and the GNUstep
NSArchiver class is functional, but not strongly tested.  It does not
yet call -awakeUsingCoder:.

I have separated the high-level archiving of groups of objects from the
low-level format of how C-types are written.  There are several new
classes.  CStream is a subclass of Stream that knows how to encode
C-type variables in a machine independent way; this class has two
concrete subclasses: BinaryCStream, and TextCStream.  Plug these
backends into Coder to get different style low-level formats for
archiving.

Floats and doubles are now encoded more efficiently.

NSArchiver is built on top of Coder.  You can actually send all the
Coder methods to NSArchiver and vice-versa.

GNU classes BinaryCoder and TextCoder are gone.

@item Several new OpenStep functions have been implemented:
NSHomeDirectory, NSUserName, NSHomeDirectoryForUser, NSPageSize,
NSLogPageSize, NSroundUpToMultipleOfPageSize,
NSRoundDownToMultipleOfPageSize, NSRealMemoryAvailable,
NSAllocateMemoryPages, NSDeallocateMemoryPages, NSCopyMemoryPages.

@section Noteworthy changes since version @samp{0.1.14}

@itemize @bullet

@item Can be made as a shared library by passing @samp{--enabled-shared} to
`configure'.  Thanks to Jan Kybic @email{kybic@@earn.cvut.cz} and Bryan Headley
@email{bwh@@mail.lnd.coretech.com} for suggestions.

@item New classes NSSet, NSMutableSet, NSCountedSet.  New concrete
classes NSGSet, NSGMutableSet, NSGCountedSet.  New test program nsset.m.
New class NSMethodSignature.

@item Running './configure' and building the library in a different
directory than the source works as it should, according to the GNU
standards. 

@item Dynamic loading fixes for Solaris, thanks to Adam Fedor.

@item Fixes to Coder correct bugs with encoding/decoding wildly
interconnected objects.  (My application uses a "Suffix Tree" structure:
a Tree, and a LinkedList that winds its way through the leaves of the
tree; the LinkedList nodes also have pointers back to the tree nodes.)

@item NSTimeZone implemented, thanks to Peter Burka
@email{peter@@bert.psyc.upei.ca}

@item NSData fixes, thanks to Adam Fedor.

@item NSObjCRuntime functions implemented.  NSObject description methods
implemented.

@item Bug fixes in NSString, NSDictionary, NSArray, NSGeometry and other
places.

@section Noteworthy changes since version @samp{0.1.12}

@itemize @bullet

@item Bug fixes: installation; NSArray and NSDictionary copying;
NSArray, NSDictionary, NSData, NSArchiver, NSUnarchiver concrete class
configurability; NSString -getCharacter:range:. See the ChangeLog for
more details.

@end itemize

@section Noteworthy changes since version @samp{0.1.10}

@itemize @bullet

@item Now using @file{src}, @file{config} and @file{doc} directories to
un-clutter the top-level directory.

@item
New GNUStep classes implemented: NSDictionary, NSMutableDictionary;
concrete classes NSGDictionary, NSGMutableDictionary; enumeration
classes NSGDictionaryKeyEnumerator, NSGDictionaryObjectEnumerator.

@item
More methods in NSData are implemented, thanks to Albin Jones.

@item
More methods in NSString are implemented; we have new classes
NSCharacterSet and NSBitmapCharSet; all thanks to Adam Fedor.

@item
And several bug fixes.  See the ChangeLog for details.

@end itemize

@section Noteworthy changes since version @samp{0.1.9}

@itemize @bullet

@item
Renamed "foundation" include file directory to "Foundation", in
accordance with OpenStep.

@item
Several bug fixes, including a problem with a missing file in 0.1.9.

@end itemize

@section Noteworthy changes since version @samp{0.1.8}

@itemize @bullet

@item
Many new GNUStep classes: NSEnumerator, NSArrayEnumerator, NSCoder,
NSArchiver, NSUnarchiver, NSData, NSMutableData, NSGCoder, NSGArchiver,
NSGUnarchiver, NSGData, NSGMutableData.  Much coding and prep work has
been done to make archiving work (see the ChangeLog), but it's not quite
ready for action yet.

@item
New GNUStep classes implemented by others: Thanks to Adam Fedor,
NSAssertionHandler.  Thanks to Jeremy Bettis, NSDate.

@item
Overhauled encoding and decoding.  The Coder now sends -initWithCoder by
default, but will still send the more flexible +newWithCoder if the
class implements it.  See objects/Coding.h.  The Stream class interface
has been changed slightly.  There are two new protocols for Streams.

@item
Several new debug-aiding methods implemented in NSAutoreleasePool.

@item
Separated Constant Collection protocols from changeable ones.
Eventually I'll separate the classes too.

@item
Included an outline for the GNU Objective C Language Manual.  The GNU
project is looking for volunteers to help flesh it out.  Send email to
Martin Michlmayr @email{tbm@@ihq.com} or Andrew McCallum
@email{mccallum@@gnu.ai.mit.edu}.

@item
Include the AUTHORS file, needed for legal reasons.  Include the
@file{GNUStep-volunteers} file.

@item
Several bug fixes:  Typo in Array.m; Linux header file frobbing in
NSZone.h; typo causing crash in checks/nsarray.m; bad deallocation in
Collection.m; typo in BinaryTree.m; put -write: and -read:
implementations back in Collection.m.

@end itemize

@section Noteworthy changes since version @samp{0.1.7}

@itemize @bullet

@item
Thanks to Adam Fedor @email{fedor@@boulder.colorado.edu}, classes NSBundle,
NSNumber and NSValue are now operational.  He also provided stubs for
NSArray, NSCoder and NSDictionary.  

@item
NSArray has been fleshed out.  There are new classes NSConcreteArray and
NSConcreteMutableArray.  Basic operations with the NSArray class cluster
now work, and it is set up to coexist nicely with the GNU collection
heirarchy.  Next I'll do NSDictionary in a similar style.

@item
From Adam Fedor, there is a new patch to the gcc Objective C runtime
that aids dynamic linking.  You'll have to apply this patch and
reinstall the runtime before you can compile this version of libgnustep-base.

@item
Several bug fixes, including two serious ones in Collection deallocation
and behavior adding.  See the ChangeLog for details.

@end itemize

@section Noteworthy changes since version @samp{0.1.5}

@itemize @bullet

@item
Better string handling.  NSString is now fleshed out, and I've
implemented a scheme by which the GNU String object and OpenStep's
NSString can coexist nicely.  The OpenStep classes declare their string
arguments with (NSString*) just like the standard says, but the
preferred (more flexible) way to declare string arguments is (id
<String>); and these two types are set up so that they coexist.  There
is still more to be done.  NSString has several unimplemented methods;
GNU String needs some more work.

@item
Newly implemented classes: MallocAddress, NSString, NSMutableString,
NSCString, NSMutableCString.

@item
Thanks to Pieter Schoenmakers @email{tiggr@@es.ele.tue.nl} we have a new
version of the gcc-string.patch that should apply more smoothly.

@item
Thanks to Adam Fedor @email{fedor@@boulder.colorado.edu} for a bug fix to
NXStringTable's.

@item
Thanks to Mark Lakata @email{lakata@@nsdssp.lbl.gov} for a bug fix to NSZone.c.

@ignore
@item
Thanks to Jeremy Bettis @email{jbettis@cse.unl.edu} for implementing NSDate. 
(We're waiting for the assignment paperwork to go through before it's
included in the release.)
@end ignore

@item
Several bug fixes.  Thanks to those who reported them.  Credits are in
the ChangeLog.

@end itemize

@section Noteworthy changes since version @samp{0.1.3}

This release not well tested at all.  We desperately need someone to
write a test suite using dejagnu.  Any volunteers?

I made this release now in order to share the progress that is being
made on GNUSTEP.

@itemize @bullet

@item
New GNUSTEP implementations: NSObject, NSAutoreleasePool, NSZone.
Thanks to Mark Lakata for NSZone.

@item
New GNUSTEP implementations included, but not compiled: NSBundle,
NSException, NSGeometry, NSNumber, NSValue.  Many thanks Adam Fedor.

@item
Many new GNU classes: String classes!  String, MutableString,
ConstantString.  One interesting feature of the GNU string classes is
that that, just like in Smalltalk, they are part of the Collection
heirarchy---all the methods you are used to using on other collections
can be used on these "collections of characters".  You can create
ConstantStrings using the @@"" syntax.

@item Entire library converted to use @code{retain}, @code{release},
@code{autorelease}, @code{dealloc} instead of @code{free}.

@end itemize

@section Noteworthy changes since version @samp{0.1.0}

@itemize @bullet

@item New category: ObjectRetaining.  New classes: AutoreleasePool,
AutoreleaseStack.

@item Bug fixes: Install next-includes properly.  New instructions in
README.ULTRIX.  Time.m patched for Solaris 2.4.  test12.m free fix.

@end itemize

@section Noteworthy changes in version @samp{0.1.0}

@itemize @bullet

@item Renamed the library from @samp{libcoll} to @samp{libgnustep-base}.
(See the end of the file @samp{DISCUSSION} for the background on this
name choice.)  Several file names changed to reflect this.  GNU class
interfaces are now included with @samp{objects} prefix,
e.g. @samp{#include <objects/BinaryTree.h>}.

@item Many new classes. Pseudo-random number classes Random, RNGBerkeley
and RNGAdditiveCongruential.  New stream classes Stream, StdioStream and
MemoryStream.  New coder classes Coder, TextCoder and BinaryCoder.  New
network packet transmission classes Port and SocketPort.  New remote
object messaging classes Connection, Proxy and ConnectedCoder.  New
protocols Coding and Retaining.  New, but unimplemented: Lock and
Locking.  New but soon-to-disapppear: RetainingNotifier,
InvalidationListening.

@item Some bug fixes:  Fixed the assert typo in Storage.m.  The Time
class now compiles under Solaris.  Fixed insertion bug in CircularArray.
NXStringTable_scan.l can now be compiled with lex, not just flex,
(thanks to Adam Fedor @email{adam@@bastille.rmnug.org}).  Properly detect the
difference between gcc running under NEXTSTEP and NeXT's cc.  Using 
autoconf version 2.0.  Renamed DelegateList to DelegatePool.  Renamed
some collection hierarchy methods for better consistency.

@item Some directory reorganization so that NeXT-compatible files can be
included in the standard way, e.g. #include <objc/List.h>.  Some other
NeXT-compatibility improvements: Changed @samp{GNU} prefix to @samp{NX}
in List and HashTable.  New files zone.[hc] containing dummy stubs for
NeXT-compatible zone functions.

@end itemize

@section Noteworthy changes in version @samp{940524}

@itemize @bullet

@item A NeXT-compatible NXStringTable object, thanks to Adam Fedor
@email{adam@@bastille.rmnug.org}.

@item
SplayTree and RBTree classes now operational.  More methods in Time
class implemented.

@item
Some API cleanup:  -delegateListList changed to -delegateListCollection.
-includesSameContents: changed to -contentsEqual:.  -insertObject:atKey:
changed to -putObject:atKey:.  See the ChangeLog for more detail.

@item
Configuration by autoconf in the self-tests directory.  Configuration
script tests GCC nested functions.  Configuration script detects
NEXTSTEP and makes the appropriate adjustments, including skipping the
NeXT-compatibility classes.

@item
Bug fixes: BinaryTree rotate methods fixed.  Fixed the way
@code{ifNone:} and @code{ifAbsent:} functions were called.  Fixed the
way long elements are printed.  Added methods for preventing memory
leaks by unfinished enumerations: @code{-newEnumState} and
@code{-freeEnumState:}.  Several bug fixes in List and Storage; changes
for better NeXT-compability.  And more.

@end itemize

@section Noteworthy changes in version @samp{931026}

@itemize @bullet

@item
Installation using @samp{./configure} and @samp{autoconf}

@item
New BinaryTree and RBTree(unfinished) classes.  Rewritten LinkedList
class.

@item
A new scheme for holding non-object elements in classes that require
  object contents; EltNodeCollector class.

@item
Archiving with -write: and -read: methods.  This involved removing the
ability to set the comparison function independent of content type.

@item
Removed COLL_NO_ELEMENT and friends.  Now there are no arbitrary
restrictions on which long int's can be stored.  Like in Smalltalk,
...ifAbsentCall: methods have been added to replace this functionalty.

@item
Added a LABMDA() macro for defining small functions in the arg position.

@item
Removed many ...perform: methods.  Use instead the more flexible 
...call: methods with LABMDA().

@item
Renamed ...Description: methods to ...Encoding: for better use of
already-defined objc keyword: @@encode().

@item
New in the Collecting protocol:
Filtered enumerating instead of filtered shallowCopy'ing.
Enumerations still safe when modifying the contents.

@item
The beginnings of documentation in libcoll.texi.

@item
Many bug fixes.

@item
...and more.
