Warning: this 1074189592Sbms is incompatible with previous versions of zlib which returned Z_OK. 1075189592Sbms- work around a TurboC compiler bug (bad code for b << 0, see infutil.h) 1076189592Sbms (actually that was not a compiler bug, see 0.81 above) 1077189592Sbms- gzread no longer reads one extra byte in certain cases 1078189592Sbms- In gzio destroy(), don't reference a freed structure 1079189592Sbms- avoid many warnings for MSDOS 1080189592Sbms- avoid the ERROR symbol which is used by MS Windows 1081189592Sbms 1082189592SbmsChanges in 0.71 (14 April 95) 1083189592Sbms- Fixed more MSDOS compilation problems :( There is still a bug with 1084189592Sbms TurboC large model. 1085189592Sbms 1086189592SbmsChanges in 0.7 (14 April 95) 1087189592Sbms- Added full inflate support. 1088189592Sbms- Simplified the crc32() interface. The pre- and post-conditioning 1089189592Sbms (one's complement) is now done inside crc32(). WARNING: this is 1090189592Sbms incompatible with previous versions; see zlib.h for the new usage. 1091189592Sbms 1092189592SbmsChanges in 0.61 (12 April 95) 1093189592Sbms- workaround for a bug in TurboC. example and minigzip now work on MSDOS. 1094189592Sbms 1095189592SbmsChanges in 0.6 (11 April 95) 1096189592Sbms- added minigzip.c 1097189592Sbms- added gzdopen to reopen a file descriptor as gzFile 1098189592Sbms- added transparent reading of non-gziped files in gzread. 1099189592Sbms- fixed bug in gzread (don't read crc as data) 1100189592Sbms- fixed bug in destroy (gzio.c) (don't return Z_STREAM_END for gzclose). 1101189592Sbms- don't allocate big arrays in the stack (for MSDOS) 1102170613Sbms- fix some MSDOS compilation problems 1103170613Sbms 1104189592SbmsChanges in 0.5: 1105170613Sbms- do real compression in deflate.c. Z_PARTIAL_FLUSH is supported but 1106170613Sbms not yet Z_FULL_FLUSH. 1107170613Sbms- support decompression but only in a single step (forced Z_FINISH) 1108189592Sbms- added opaque object for zalloc and zfree. 1109170613Sbms- added deflateReset and inflateReset 1110189592Sbms- added a variable zlib_version for consistency checking. 1111189592Sbms- renamed the 'filter' parameter of deflateInit2 as 'strategy'. 1112170613Sbms Added Z_FILTERED and Z_HUFFMAN_ONLY constants. 1113189592Sbms 1114189592SbmsChanges in 0.4: 1115170613Sbms- avoid "zip" everywhere, use zlib instead of ziplib. 1116189592Sbms- suppress Z_BLOCK_FLUSH, interpret Z_PARTIAL_FLUSH as block flush 1117189592Sbms if compression method == 8. 1118189592Sbms- added adler32 and crc32 1119170613Sbms- renamed deflateOptions as deflateInit2, call one or the other but not both 1120189592Sbms- added the method parameter for deflateInit2. 1121189592Sbms- added inflateInit2 1122189592Sbms- simplied considerably deflateInit and inflateInit by not supporting 1123170613Sbms user-provided history buffer. This is supported only in deflateInit2 1124189592Sbms and inflateInit2. 1125170613Sbms 1126189592SbmsChanges in 0.3: 1127189592Sbms- prefix all macro names with Z_ 1128189592Sbms- use Z_FINISH instead of deflateEnd to finish compression. 1129189592Sbms- added Z_HUFFMAN_ONLY 1130189592Sbms- added gzerror() 1131189592Sbms
