| - fix macros _tr_tally_* in deflate.h for debug mode (Glenn Randers-Pehrson) |
| - remove block truncation heuristic which had very marginal effect for zlib |
| (smaller lit_bufsize than in gzip 1.2.4) and degraded a little the |
| compression ratio on some files. This also allows inlining _tr_tally for |
| matches in deflate_slow. |

| - 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.) |

| avail_out as zero but there is nothing to do |
| - added memcmp for non STDC compilers |

| - 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 |

| - 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++ |

| - 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) |

| 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 |

| TurboC large model. |
| |
