Turbo C, Borland C++ 141117651Speter- faster crc32() 141217651Speter 141317651SpeterChanges in 0.8 (29 April 95) 141417651Speter- added fast inflate (inffast.c) 141517651Speter- deflate(Z_FINISH) now returns Z_STREAM_END when done. Warning: this 141617651Speter is incompatible with previous versions of zlib which returned Z_OK. 141717651Speter- work around a TurboC compiler bug (bad code for b << 0, see infutil.h) 141817651Speter (actually that was not a compiler bug, see 0.81 above) 141917651Speter- gzread no longer reads one extra byte in certain cases 142017651Speter- In gzio destroy(), don't reference a freed structure 142117651Speter- avoid many warnings for MSDOS 142217651Speter- avoid the ERROR symbol which is used by MS Windows 142317651Speter 142417651SpeterChanges in 0.71 (14 April 95) 142517651Speter- Fixed more MSDOS compilation problems :( There is still a bug with 142617651Speter TurboC large model. 142717651Speter 142817651SpeterChanges in 0.7 (14 April 95) 142917651Speter- Added full inflate support. 143017651Speter- Simplified the crc32() interface. The pre- and post-conditioning 143117651Speter (one's complement) is now done inside crc32(). WARNING: this is 143217651Speter incompatible with previous versions; see zlib.h for the new usage. 143317651Speter 143417651SpeterChanges in 0.61 (12 April 95) 143517651Speter- workaround for a bug in TurboC. example and minigzip now work on MSDOS. 143617651Speter 143717651SpeterChanges in 0.6 (11 April 95) 143817651Speter- added minigzip.c 143917651Speter- added gzdopen to reopen a file descriptor as gzFile 144017651Speter- added transparent reading of non-gziped files in gzread. 144117651Speter- fixed bug in gzread (don't read crc as data) 144217651Speter- fixed bug in destroy (gzio.c) (don't return Z_STREAM_END for gzclose). 144317651Speter- don't allocate big arrays in the stack (for MSDOS) 144417651Speter- fix some MSDOS compilation problems 144517651Speter 144617651SpeterChanges in 0.5: 144717651Speter- do real compression in deflate.c. Z_PARTIAL_FLUSH is supported but 144817651Speter not yet Z_FULL_FLUSH. 144917651Speter- support decompression but only in a single step (forced Z_FINISH) 145017651Speter- added opaque object for zalloc and zfree. 145117651Speter- added deflateReset and inflateReset 145217651Speter- added a variable zlib_version for consistency checking. 145317651Speter- renamed the 'filter' parameter of deflateInit2 as 'strategy'. 145417651Speter Added Z_FILTERED and Z_HUFFMAN_ONLY constants. 145517651Speter 145617651SpeterChanges in 0.4: 145717651Speter- avoid "zip" everywhere, use zlib instead of ziplib. 145817651Speter- suppress Z_BLOCK_FLUSH, interpret Z_PARTIAL_FLUSH as block flush 145917651Speter if compression method == 8. 146017651Speter- added adler32 and crc32 146117651Speter- renamed deflateOptions as deflateInit2, call one or the other but not both 146217651Speter- added the method parameter for deflateInit2. 146317651Speter- added inflateInit2 146417651Speter- simplied considerably deflateInit and inflateInit by not supporting 146517651Speter user-provided history buffer. This is supported only in deflateInit2 146617651Speter and inflateInit2. 146717651Speter 146817651SpeterChanges in 0.3: 146917651Speter- prefix all macro names with Z_ 147017651Speter- use Z_FINISH instead of deflateEnd to finish compression. 147117651Speter- added Z_HUFFMAN_ONLY 147217651Speter- added gzerror() 1473
