| - 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) |

| |
| 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 |
| |

| - 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 |
| - Bytef is define'd instead of typedef'ed (work around Borland bug) |
| - added an INDEX file |
| - new makefiles for DJGPP (Makefile.dj2), 32-bit Borland (Makefile.b32), |
| Watcom (Makefile.wat), Amiga SAS/C (Makefile.sas) |
| - speed up adler32 for modern machines without auto-increment |
| - added -ansi for IRIX in configure |
| - static_init_done in trees.c is an int |
| - define unlink as delete for VMS |
| - fix configure for QNX |
| - add configure branch for SCO and HPUX |
| - avoid many warnings (unused variables, dead assignments, etc...) |
| - no fdopen for BeOS |

| |

| - add optional "configure" to build zlib as a shared library |
| - suppress Makefile.qnx, use configure instead |
| - fixed deflate for 64-bit systems (detected on Cray) |
| - fixed inflate_blocks for 64-bit systems (detected on Alpha) |
| - declare Z_DEFLATED in zlib.h (possible parameter for deflateInit2) |
| - always return Z_BUF_ERROR when deflate() has nothing to do |
| - deflateInit and inflateInit are now macros to allow version checking |
| - prefix all global functions and types with z_ with -DZ_PREFIX |
| - make falloc completely reentrant (inftrees.c) |
| - 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 |

| - check for WIN32 in zconf.h and zutil.c (avoid farmalloc in 32-bit mode) |
| - 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++ |

| - 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) |
| - support MSDOS medium model |
| - fix deflate with flush (could sometimes generate bad output) |
| - fix deflateReset (zlib header was incorrectly suppressed) |

| - For deflate with flush, flush even if no more input is provided |
| - rename libgz.a as libz.a |

| |
| Changes in 0.93 (25 June 95) |
| - temporarily disable inline functions |
| - make deflate deterministic |
| - give enough lookahead for PARTIAL_FLUSH |
| - Set binary mode for stdin/stdout in minigzip.c for OS/2 |
| - don't even use signed char in inflate (not portable enough) |

| |
| Changes in 0.91 (2 May 95) |
| - Default MEM_LEVEL is 8 (not 9 for Unix) as documented in zlib.h |
| - Document the memory requirements in zconf.h |
| - added "make install" |

| 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 |
| - moved MAX_WBITS to zconf.h because users might want to change that |
| - document explicitly that zalloc(64K) on MSDOS must return a normalized |
| pointer (zero offset) |
| - 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 |
| - avoid the ERROR symbol which is used by MS Windows |
| |
| Changes in 0.71 (14 April 95) |
| - Fixed more MSDOS compilation problems :( There is still a bug with |
| TurboC large model |
| |
| Changes in 0.7 (14 April 95) |
| - Added full inflate support |
| - Simplified the crc32() interface. The pre- and post-conditioning |

| - fixed bug in destroy (gzio.c) (don't return Z_STREAM_END for gzclose) |
| - don't allocate big arrays in the stack (for MSDOS) |
| - fix some MSDOS compilation problems |
| |

| - added opaque object for zalloc and zfree |
| - added deflateReset and inflateReset |
| - added a variable zlib_version for consistency checking |
| - renamed the 'filter' parameter of deflateInit2 as 'strategy' |

| 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 |
| - simplified considerably deflateInit and inflateInit by not supporting |
| user-provided history buffer. This is supported only in deflateInit2 |
| and inflateInit2 |
