        How to use compress(), uncompress() and the gz* functions from VB
 | 
						|
- pass params -f (filtered data), -h (huffman only), -1 to -9 (compression
 | 
						|
  level) in minigzip (thanks to Tom Lane)
 | 
						|
 | 
						|
- use const for rommable constants in deflate
 | 
						|
- added test for gzseek and gztell in example.c
 | 
						|
- add undocumented function inflateSyncPoint() (hack for Paul Mackerras)
 | 
						|
- add undocumented function zError to convert error code to string
 | 
						|
  (for Tim Smithers)
 | 
						|
- Allow compilation of gzio with -DNO_DEFLATE to avoid the compression code
 | 
						|
- Use default memcpy for Symantec MSDOS compiler
 | 
						|
- Add EXPORT keyword for check_func (needed for Windows DLL)
 | 
						|
- add current directory to LD_LIBRARY_PATH for "make test"
 | 
						|
- create also a link for libz.so.1
 | 
						|
- added support for FUJITSU UXP/DS (thanks to Toshiaki Nomura)
 | 
						|
- use $(SHAREDLIB) instead of libz.so in Makefile.in (for HPUX)
 | 
						|
- added -soname for Linux in configure (Chun-Chung Chen,
 | 
						|
- assign numbers to the exported functions in zlib.def (for Windows DLL)
 | 
						|
- add advice in zlib.h for best usage of deflateSetDictionary
 | 
						|
- work around compiler bug on Atari (cast Z_NULL in call of s->checkfn)
 | 
						|
- allow compilation with ANSI keywords only enabled for TurboC in large model
 | 
						|
- avoid "versionString"[0] (Borland bug)
 | 
						|
- add NEED_DUMMY_RETURN for Borland
 | 
						|
- use variable z_verbose for tracing in debug mode (L. Peter Deutsch)
 | 
						|
- allow compilation with CC
 | 
						|
- defined STDC for OS/2 (David Charlap)
 | 
						|
- limit external names to 8 chars for MVS (Thomas Lund)
 | 
						|
- in minigzip.c, use static buffers only for 16-bit systems
 | 
						|
- fix suffix check for "minigzip -d foo.gz"
 | 
						|
- do not return an error for the 2nd of two consecutive gzflush() (Felix Lee)
 | 
						|
- use _fdopen instead of fdopen for MSC >= 6.0 (Thomas Fanslau)
 | 
						|
- added makelcc.bat for lcc-win32 (Tom St Denis)
 | 
						|
- in Makefile.dj2, use copy and del instead of install and rm (Frank Donahoe)
 | 
						|
- Avoid expanded $Id$. Use "rcs -kb" or "cvs admin -kb" to avoid Id expansion
 | 
						|
- check for unistd.h in configure (for off_t)
 | 
						|
- remove useless check parameter in inflate_blocks_free
 | 
						|
- avoid useless assignment of s->check to itself in inflate_blocks_new
 | 
						|
- do not flush twice in gzclose (thanks to Ken Raeburn)
 | 
						|
- rename FOPEN as F_OPEN to avoid clash with /usr/include/sys/file.h
 | 
						|
- use NO_ERRNO_H instead of enumeration of operating systems with errno.h
 | 
						|
- work around buggy fclose on pipes for HP/UX
 | 
						|
- support zlib DLL with BORLAND C++ 5.0 (thanks to Glenn Randers-Pehrson)
 | 
						|
- fix configure if CC is already equal to gcc
 | 
						|

Changes in 1.0.5 (3 Jan 98)
 | 
						|
- Fix inflate to terminate gracefully when fed corrupted or invalid data
 | 
						|
- Use const for rommable constants in inflate
 | 
						|
- Eliminate memory leaks on error conditions in inflate
 | 
						|
- Removed some vestigial code in inflate
 | 
						|
- Update web address in README
 | 
						|
 | 
						|
Changes in 1.0.4 (24 Jul 96)
 | 
						|
- In very rare conditions, deflate(s, Z_FINISH) could fail to produce an EOF
 | 
						|
  bit, so the decompressor could decompress all the correct data but went
 | 
						|
  on to attempt decompressing extra garbage data. This affected minigzip too
 | 
						|
- zlibVersion and gzerror return const char* (needed for DLL)
 | 
						|
- port to RISCOS (no fdopen, no multiple dots, no unlink, no fileno)
 | 
						|
- use z_error only for DEBUG (avoid problem with DLLs)
 | 
						|
 | 
						|
Changes in 1.0.3 (2 Jul 96)
 | 
						|
- use z_streamp instead of z_stream *, which is now a far pointer in MSDOS
 | 
						|
  small and medium models; this makes the library incompatible with previous
 | 
						|
  versions for these models. (No effect in large model or on other systems.)
 | 
						|
- return OK instead of BUF_ERROR if previous deflate call returned with
 | 
						|
  avail_out as zero but there is nothing to do
 | 
						|
- added memcmp for non STDC compilers
 | 
						|
- define NO_DUMMY_DECL for more Mac compilers (.h files merged incorrectly)
 | 
						|
- define __32BIT__ if __386__ or i386 is defined (pb. with Watcom and SCO)
 | 
						|
- better check for 16-bit mode MSC (avoids problem with Symantec)
 | 
						|
 | 
						|
Changes in 1.0.2 (23 May 96)
 | 
						|
- added Windows DLL support
 | 
						|
- added a function zlibVersion (for the DLL support)
 | 
						|
- fixed declarations using Bytef in infutil.c (pb with MSDOS medium model)
 | 
						|
- Bytef is define's instead of typedef'd only for Borland C
 | 
						|
- avoid reading uninitialized memory in example.c
 | 
						|
- mention in README that the zlib format is now RFC1950
 | 
						|
- updated Makefile.dj2
 | 
						|
- added algorithm.doc
 | 
						|
 | 
						|
Changes in 1.0.1 (20 May 96) [1.0 skipped to avoid confusion]
 | 
						|
- fix array overlay in deflate.c which sometimes caused bad compressed data
 | 
						|
- fix inflate bug with empty stored block
 | 
						|
- fix MSDOS medium model which was broken in 0.99
 | 
						|
- fix deflateParams() which could generate bad compressed data
 | 
						|

 | 
						|

- speed up adler32 for modern machines without auto-increment
 | 
						|
- added -ansi for IRIX in configure
 | 
						|

 | 
						|
- define unlink as delete for VMS
 | 
						|
- fix configure for QNX
 | 
						|

						|
- fix the Watcom fix for 32 bit mode (define FAR as empty)
 | 
						|
- removed redefinition of Byte for MKWERKS
 | 
						|
- work around an MWKERKS bug (incorrect merge of all .h files)
 | 
						|
 | 
						|
Changes in 0.99 (27 Jan 96)
 | 
						|
- allow preset dictionary shared between compressor and decompressor
 | 
						|
- allow compression level 0 (no compression)

						|
- fixed very unlikely race condition in ct_static_init
 | 
						|
- free in reverse order of allocation to help memory manager
 | 
						|
- use zlib-1.0/* instead of zlib/* inside the tar.gz
 | 
						|
- make zlib warning-free with "gcc -O3 -Wall -Wwrite-strings -Wpointer-arith
 | 
						|
  -Wconversion -Wstrict-prototypes -Wmissing-prototypes"
 | 
						|
- allow gzread on concatenated .gz files
 |

 | 
						|
- Document Z_SYNC_FLUSH
 | 
						|
- add uninstall in Makefile
 | 
						|

 | 
						|
- fix typo in Make_vms.com (f$trnlnm -> f$getsyi)
 | 
						|
- in fcalloc, normalize pointer if size > 65520 bytes
 | 
						|
- don't use special fcalloc for 32 bit Borland C++
 | 
						|
- use STDC instead of __GO32__ to avoid redeclaring exit, calloc, etc.
 | 
						|

 | 
						|
- allow "a" as mode in gzopen
 | 
						|
- fix error checking in gzread
 | 
						|
- allow skipping .gz extra-field on pipes

 | 
						|
- Watcom C pretends to be Microsoft C small model even in 32 bit mode
 | 
						|
- don't use unsized arrays to avoid silly warnings by Visual C++:
 | 
						|
     warning C4746: 'inflate_mask' : unsized array treated as  '__far'
 | 
						|
     (what's wrong with far data in far model?)
 | 
						|
- define enum out of inflate_blocks_state to allow compilation with C++
 | 
						|
 | 
						|
Changes in 0.95 (16 Aug 95)
 | 
						|
- fix MSDOS small and medium model (now easier to adapt to any compiler)
 | 
						|
- inlined send_bits
 | 
						|
- fix the final (:-) bug for deflate with flush (output was correct but
 | 
						|
  not completely flushed in rare occasions)
 | 
						|
- default window size is same for compression and decompression
 | 
						|
  (it's now sufficient to set MAX_WBITS in zconf.h)
 | 
						|
- voidp -> voidpf and voidnp -> voidp (for consistency with other
 | 
						|
  typedefs and because voidnp was not near in large model)
 | 
						|
 | 
						|
Changes in 0.94 (13 Aug 95)
 | 
						|

 | 
						|

 | 
						|
- avoid various warnings in gzio.c, example.c, infblock.c, adler32.c, zutil.c
 | 
						|
- avoid reserved word 'new' in trees.c
 | 
						|
 | 
						|

 | 
						|
- added support for DJGPP
 | 
						|
 | 
						|
Changes in 0.9 (1 May 95)
 | 
						|
- don't assume that zalloc clears the allocated memory (the TurboC bug
 | 
						|
  was Mark's bug after all :)
 | 
						|
- let again gzread copy uncompressed data unchanged (was working in 0.71)
 | 
						|
- deflate(Z_FULL_FLUSH), inflateReset and inflateSync are now fully implemented
 | 
						|
- added a test of inflateSync in example.c
 | 
						|

						|
- added Makefiles for Microsoft C, Turbo C, Borland C++
 | 
						|
- faster crc32()
 | 
						|
 | 
						|
Changes in 0.8 (29 April 95)
 | 
						|
- added fast inflate (inffast.c)
 | 
						|
- deflate(Z_FINISH) now returns Z_STREAM_END when done. Warning: this
 | 
						|
  is incompatible with previous versions of zlib which returned Z_OK
 | 
						|
- work around a TurboC compiler bug (bad code for b << 0, see infutil.h)
 | 
						|
  (actually that was not a compiler bug, see 0.81 above)
 | 
						|
- gzread no longer reads one extra byte in certain cases
 | 
						|
- In gzio destroy(), don't reference a freed structure
 | 
						|
- avoid many warnings for MSDOS

 | 
						|
 | 
						|
Changes in 0.7 (14 April 95)
 | 
						|
- Added full inflate support
 | 
						|
- Simplified the crc32() interface. The pre- and post-conditioning
 | 
						|
  (one's complement) is now done inside crc32(). WARNING: this is
 | 
						|
  incompatible with previous versions; see zlib.h for the new usage
 | 
						|
 | 
						|
Changes in 0.61 (12 April 95)
 | 
						|

- added transparent reading of non-gziped files in gzread
 | 
						|
- fixed bug in gzread (don't read crc as data)
 | 
						|

 | 
						|
- don't allocate big arrays in the stack (for MSDOS)
 | 
						|
- fix some MSDOS compilation problems
 | 
						|
 | 
						|
Changes in 0.5:
 | 
						|
- do real compression in deflate.c. Z_PARTIAL_FLUSH is supported but
 | 
						|
  not yet Z_FULL_FLUSH
 | 
						|
- support decompression but only in a single step (forced Z_FINISH)
 | 
						|

 | 
						|
  Added Z_FILTERED and Z_HUFFMAN_ONLY constants
 | 
						|
 | 
						|
Changes in 0.4:
 | 
						|
- avoid "zip" everywhere, use zlib instead of ziplib
 | 
						|
- suppress Z_BLOCK_FLUSH, interpret Z_PARTIAL_FLUSH as block flush
 | 
						|
  if compression method == 8
 | 
						|
- added adler32 and crc32
 | 
						|
- renamed deflateOptions as deflateInit2, call one or the other but not both
 | 
						|
- added the method parameter for deflateInit2
 | 
						|
- added inflateInit2
 |

  user-provided history buffer. This is supported only in deflateInit2
 | 
						|
  and inflateInit2

Changes in 0.3:
 | 
						|
- prefix all macro names with Z_
 |

 | 
						|
- added gzerror()
 |
