| 4Changes in 1.1.1 (27 Feb 98)
5- fix macros _tr_tally_* in deflate.h for debug mode (Glenn Randers-Pehrson)
6- remove block truncation heuristic which had very marginal effect for zlib
7 (smaller lit_bufsize than in gzip 1.2.4) and degraded a little the
8 compression ratio on some files. This also allows inlining _tr_tally for
9 matches in deflate_slow.
10- added msdos/Makefile.w32 for WIN32 Microsoft Visual C++ (Bob Frazier)
11

4Changes in 1.0.4 (24 Jul 96)
5- In very rare conditions, deflate(s, Z_FINISH) could fail to produce an EOF
6 bit, so the decompressor could decompress all the correct data but went
7 on to attempt decompressing extra garbage data. This affected minigzip too.
8- zlibVersion and gzerror return const char* (needed for DLL)
9- port to RISCOS (no fdopen, no multiple dots, no unlink, no fileno)
10- use z_error only for DEBUG (avoid problem with DLLs)
