| 24 | The main changes since 1.0.3 are: | ||
| 25 | |||
| 26 | - In very rare conditions, deflate(s, Z_FINISH) could fail to produce an EOF | ||
| 27 | bit, so the decompressor could decompress all the correct data but went | ||
| 28 | on to attempt decompressing extra garbage data. This affected minigzip too. | ||
| 29 | - zlibVersion and gzerror return const char* (needed for DLL) | ||
| 30 | - port to RISCOS (no fdopen, no multiple dots, no unlink, no fileno) | ||

| 22 | The changes made in version 1.0.2 are documented in the file ChangeLog. | ||
| 23 | The main changes since 0.99 are: | ||
| 24 | |||
| 25 | - fix array overlay in deflate.c which sometimes caused bad compressed data | ||
| 26 | - fix inflate bug with empty stored block | ||
| 27 | - fix MSDOS medium model which was broken in 0.99 | ||
| 28 | - fix deflateParams() which could generated bad compressed data. | ||
| 29 | - added an INDEX file | ||
| 30 | - new makefiles for DJGPP (Makefile.dj2), 32-bit Borland (Makefile.b32), | ||
| 31 | Watcom (Makefile.wat), Amiga SAS/C (Makefile.sas) | ||
| 32 | - several portability improvements | ||
| 33 | - added algorithm.doc | ||
| 34 | - added Windows DLL support | ||
| 35 | - added a function zlibVersion (for the DLL support) | ||
