1 ChangeLog file for zlib
3 Changes in 0.8 (29 April 95)
4 - added fast inflate (inffast.c)
5 - deflate(Z_FINISH) now returns Z_STREAM_END when done. Warning: this
6 is incompatible with previous versions of zlib which returned Z_OK.
7 - work around a TurboC compiler bug (bad code for b << 0, see infutil.h)
8 - gzread no longer reads one extra byte in certain cases
9 - In gzio destroy(), don't reference a freed structure
10 - avoid many warnings for MSDOS
11 - avoid the ERROR symbol which is used by MS Windows
13 Changes in 0.71 (14 April 95)
14 - Fixed more MSDOS compilation problems :( There is still a bug with
17 Changes in 0.7 (14 April 95)
18 - Added full inflate support.
19 - Simplified the crc32() interface. The pre- and post-conditioning
20 (one's complement) is now done inside crc32(). WARNING: this is
21 incompatible with previous versions; see zlib.h for the new usage.
23 Changes in 0.61 (12 April 95)
24 - workaround for a bug in TurboC. example and minigzip now work on MSDOS.
26 Changes in 0.6 (11 April 95)
28 - added gzdopen to reopen a file descriptor as gzFile
29 - added transparent reading of non-gziped files in gzread.
30 - fixed bug in gzread (don't read crc as data)
31 - fixed bug in destroy (gzio.c) (don't return Z_STREAM_END for gzclose).
32 - don't allocate big arrays in the stack (for MSDOS)
33 - fix some MSDOS compilation problems
36 - do real compression in deflate.c. Z_PARTIAL_FLUSH is supported but
38 - support decompression but only in a single step (forced Z_FINISH)
39 - added opaque object for zalloc and zfree.
40 - added deflateReset and inflateReset
41 - added a variable zlib_version for consistency checking.
42 - renamed the 'filter' parameter of deflateInit2 as 'strategy'.
43 Added Z_FILTERED and Z_HUFFMAN_ONLY constants.
46 - avoid "zip" everywhere, use zlib instead of ziplib.
47 - suppress Z_BLOCK_FLUSH, interpret Z_PARTIAL_FLUSH as block flush
48 if compression method == 8.
49 - added adler32 and crc32
50 - renamed deflateOptions as deflateInit2, call one or the other but not both
51 - added the method parameter for deflateInit2.
53 - simplied considerably deflateInit and inflateInit by not supporting
54 user-provided history buffer. This is supported only in deflateInit2
58 - prefix all macro names with Z_
59 - use Z_FINISH instead of deflateEnd to finish compression.
60 - added Z_HUFFMAN_ONLY
