3 Changes in 0.79 (28 April 95)
4 - add fast inflate (inffast.c)
5 - In gzio destroy(), don't reference a freed structure
6 - avoid many warnings for MSDOS
8 Changes in 0.71 (14 April 95)
9 - Fixed more MSDOS compilation problems :( There is still a bug with
12 Changes in 0.7 (14 April 95)
13 - Added full inflate support.
14 - Simplified the crc32() interface. The pre- and post-conditioning
15 (one's complement) is now done inside crc32(). WARNING: this is
16 incompatible with previous versions; see zlib.h for the new usage.
18 Changes in 0.61 (12 April 95)
19 - workaround for a bug in TurboC. example and minigzip now work on MSDOS.
21 Changes in 0.6 (11 April 95)
23 - added gzdopen to reopen a file descriptor as gzFile
24 - added transparent reading of non-gziped files in gzread.
25 - fixed bug in gzread (don't read crc as data)
26 - fixed bug in destroy (gzio.c) (don't return Z_STREAM_END for gzclose).
27 - don't allocate big arrays in the stack (for MSDOS)
28 - fix some MSDOS compilation problems
31 - do real compression in deflate.c. Z_PARTIAL_FLUSH is supported but
33 - support decompression but only in a single step (forced Z_FINISH)
34 - added opaque object for zalloc and zfree.
35 - added deflateReset and inflateReset
36 - added a variable zlib_version for consistency checking.
37 - renamed the 'filter' parameter of deflateInit2 as 'strategy'.
38 Added Z_FILTERED and Z_HUFFMAN_ONLY constants.
41 - avoid "zip" everywhere, use zlib instead of ziplib.
42 - suppress Z_BLOCK_FLUSH, interpret Z_PARTIAL_FLUSH as block flush
43 if compression method == 8.
44 - added adler32 and crc32
45 - renamed deflateOptions as deflateInit2, call one or the other but not both
46 - added the method parameter for deflateInit2.
48 - simplied considerably deflateInit and inflateInit by not supporting
49 user-provided history buffer. This is supported only in deflateInit2
53 - prefix all macro names with Z_
54 - use Z_FINISH instead of deflateEnd to finish compression.
55 - added Z_HUFFMAN_ONLY
