4 - Fixed more MSDOS compilation problems :( There is still a bug with
7 Changes in 0.7 (14 April 95)
8 - Added full inflate support.
9 - Simplified the crc32() interface. The pre- and post-conditioning
10 (one's complement) is now done inside crc32(). WARNING: this is
11 incompatible with previous versions; see zlib.h for the new usage.
13 Changes in 0.61 (12 April 95)
14 - workaround for a bug in TurboC. example and minigzip now work on MSDOS.

18 - added gzdopen to reopen a file descriptor as gzFile
19 - added transparent reading of non-gziped files in gzread.
20 - fixed bug in gzread (don't read crc as data)
21 - fixed bug in destroy (gzio.c) (don't return Z_STREAM_END for gzclose).
22 - don't allocate big arrays in the stack (for MSDOS)
23 - fix some MSDOS compilation problems
26 - do real compression in deflate.c. Z_PARTIAL_FLUSH is supported but
28 - support decompression but only in a single step (forced Z_FINISH)
29 - added opaque object for zalloc and zfree.
30 - added deflateReset and inflateReset
31 - added a variable zlib_version for consistency checking.
32 - renamed the 'filter' parameter of deflateInit2 as 'strategy'.
33 Added Z_FILTERED and Z_HUFFMAN_ONLY constants.
36 - avoid "zip" everywhere, use zlib instead of ziplib.
37 - suppress Z_BLOCK_FLUSH, interpret Z_PARTIAL_FLUSH as block flush
38 if compression method == 8.
39 - added adler32 and crc32
40 - renamed deflateOptions as deflateInit2, call one or the other but not both
41 - added the method parameter for deflateInit2.
43 - simplied considerably deflateInit and inflateInit by not supporting
44 user-provided history buffer. This is supported only in deflateInit2
48 - prefix all macro names with Z_
49 - use Z_FINISH instead of deflateEnd to finish compression.
50 - added Z_HUFFMAN_ONLY
