1592N/A level) in minigzip (thanks to Tom Lane)
1592N/A- use const for rommable constants in deflate
1592N/A- add undocumented function inflateSyncPoint() (hack for Paul Mackerras)
1592N/A- add undocumented function zError to convert error code to string
1592N/A- Allow compilation of gzio with -DNO_DEFLATE to avoid the compression code.
1592N/A- Use default memcpy for Symantec MSDOS compiler.

1592N/A- added support for FUJITSU
UXP/DS (thanks to Toshiaki Nomura)
1592N/A- added -soname for Linux in configure (Chun-Chung Chen,
1592N/A- assign numbers to the exported functions in
zlib.def (for Windows DLL)

zlib.h for best usage of deflateSetDictionary
1592N/A- work around compiler bug on Atari (cast Z_NULL in call of s->checkfn)
1592N/A- allow compilation with ANSI keywords only enabled for TurboC in large model
1592N/A- avoid "versionString"[0] (Borland bug)

1592N/A- Update web address in README
1592N/AChanges in 1.0.4 (24 Jul 96)
1592N/A- In very rare conditions, deflate(s, Z_FINISH) could fail to produce an EOF
1592N/A bit, so the decompressor could decompress all the correct data but went
1592N/A on to attempt decompressing extra garbage data. This affected minigzip too.
1592N/A- zlibVersion and gzerror return const char* (needed for DLL)

1592N/A- use z_streamp instead of z_stream *, which is now a far pointer in MSDOS
1592N/A small and medium models; this makes the library incompatible with previous
1592N/A versions for these models. (No effect in large model or on other systems.)
1592N/A- return OK instead of BUF_ERROR if previous deflate call returned with
1592N/A avail_out as zero but there is nothing to do

zlib.h (possible parameter for deflateInit2)
1592N/A- always return Z_BUF_ERROR when deflate() has nothing to do
1592N/A- deflateInit and inflateInit are now macros to allow version checking
1592N/A- prefix all global functions and types with z_ with -DZ_PREFIX
1592N/A- fixed very unlikely race condition in ct_static_init
1592N/A- free in reverse order of allocation to help memory manager
1592N/A- make zlib warning-free with "gcc -O3 -Wall -Wwrite-strings -Wpointer-arith

1592N/A- use STDC instead of __GO32__ to avoid redeclaring exit, calloc, etc...
1592N/A- use Z_BINARY instead of BINARY
1592N/A- document that gzclose after gzdopen will close the file
1592N/A- allow "a" as mode in gzopen.
1592N/A- fix error checking in gzread
1592N/A- allow skipping .gz extra-field on pipes
1592N/A- added reference to Perl interface in README
1592N/A- put the crc table in FAR data (I dislike more and more the medium model :)
1592N/A- added a dimension to all arrays (Borland C can't count).
1592N/A- workaround Borland C bug in declaration of inflate_codes_new & inflate_fast
1592N/A- guard against multiple inclusion of *.h (for precompiled header on Mac)
1592N/A- Watcom C pretends to be Microsoft C small model even in 32 bit mode.
1592N/A- don't use unsized arrays to avoid silly warnings by Visual C++:
1592N/A warning C4746: 'inflate_mask' : unsized array treated as '__far'

1592N/A- default window size is same for compression and decompression
1592N/A- voidp -> voidpf and voidnp -> voidp (for consistency with other

deflate.c 1592N/AChanges in 0.93 (25 June 95)
1592N/A- temporarily disable inline functions
1592N/A- make deflate deterministic
1592N/A- give enough lookahead for PARTIAL_FLUSH

zlib.h 1592N/A- fix sync search logic in inflateSync
1592N/A- deflate(Z_FULL_FLUSH) now works even if output buffer too short
1592N/A- after inflateSync, don't scare people with just "lo world"
1592N/A- don't assume that zalloc clears the allocated memory (the TurboC bug
1592N/A was Mark's bug after all :)
1592N/A- let again gzread copy uncompressed data unchanged (was working in 0.71)
1592N/A- deflate(Z_FULL_FLUSH), inflateReset and inflateSync are now fully implemented
1592N/A- moved MAX_WBITS to
zconf.h because users might want to change that.
1592N/A- document explicitly that zalloc(64K) on MSDOS must return a normalized
1592N/A- added Makefiles for Microsoft C, Turbo C, Borland C++
1592N/AChanges in 0.8 (29 April 95)
1592N/A- deflate(Z_FINISH) now returns Z_STREAM_END when done. Warning: this
1592N/A is incompatible with previous versions of zlib which returned Z_OK.
1592N/A (actually that was not a compiler bug, see 0.81 above)
1592N/A- gzread no longer reads one extra byte in certain cases
1592N/A- In gzio destroy(), don't reference a freed structure
1592N/A- avoid many warnings for MSDOS
1592N/A- avoid the ERROR symbol which is used by MS Windows
1592N/AChanges in 0.71 (14 April 95)
1592N/A- Fixed more MSDOS compilation problems :( There is still a bug with
1592N/AChanges in 0.7 (14 April 95)
1592N/A- Added full inflate support.
1592N/A- Simplified the crc32() interface. The pre- and post-conditioning
1592N/A (one's complement) is now done inside crc32(). WARNING: this is
1592N/A incompatible with previous versions; see
zlib.h for the new usage.
1592N/AChanges in 0.61 (12 April 95)
1592N/A- workaround for a bug in TurboC. example and minigzip now work on MSDOS.
1592N/AChanges in 0.6 (11 April 95)

1592N/A- fix some MSDOS compilation problems
1592N/A- support decompression but only in a single step (forced Z_FINISH)

1592N/A- avoid "zip" everywhere, use zlib instead of ziplib.
1592N/A- suppress Z_BLOCK_FLUSH, interpret Z_PARTIAL_FLUSH as block flush
1592N/A if compression method == 8.
1592N/A- renamed deflateOptions as deflateInit2, call one or the other but not both
1592N/A- added the method parameter for deflateInit2.
1592N/A- simplied considerably deflateInit and inflateInit by not supporting
1592N/A user-provided history buffer. This is supported only in deflateInit2
1592N/A- prefix all macro names with Z_
1592N/A- use Z_FINISH instead of deflateEnd to finish compression.
