| - 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 |

| - fix deflateParams() which could generate bad compressed data |
| - Bytef is define'd instead of typedef'ed (work around Borland bug) |

| - 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 |

| - 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) |

| - 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 |

| - 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 |

| - added the method parameter for deflateInit2 |
| - added inflateInit2 |
