! 761: - give enough lookahead for PARTIAL_FLUSH

! 774:
! 775: Changes in 0.91 (2 May 95)
! 776: - Default MEM_LEVEL is 8 (not 9 for Unix) as documented in zlib.h
! 777: - Document the memory requirements in zconf.h
! 778: - added "make install"
! 779: - fix sync search logic in inflateSync
! 780: - deflate(Z_FULL_FLUSH) now works even if output buffer too short
! 781: - after inflateSync, don't scare people with just "lo world"
! 782: - added support for DJGPP
! 783:
! 784: Changes in 0.9 (1 May 95)
! 785: - don't assume that zalloc clears the allocated memory (the TurboC bug
! 786: was Mark's bug after all :)
! 787: - let again gzread copy uncompressed data unchanged (was working in 0.71)
! 788: - deflate(Z_FULL_FLUSH), inflateReset and inflateSync are now fully implemented
! 789: - added a test of inflateSync in example.c
! 790: - moved MAX_WBITS to zconf.h because users might want to change that.
! 791: - document explicitly that zalloc(64K) on MSDOS must return a normalized
! 792: pointer (zero offset)
! 793: - added Makefiles for Microsoft C, Turbo C, Borland C++
! 794: - faster crc32()
! 795:
! 796: Changes in 0.8 (29 April 95)
! 797: - added fast inflate (inffast.c)
! 798: - deflate(Z_FINISH) now returns Z_STREAM_END when done. Warning: this
! 799: is incompatible with previous versions of zlib which returned Z_OK.
! 800: - work around a TurboC compiler bug (bad code for b << 0, see infutil.h)
! 801: (actually that was not a compiler bug, see 0.81 above)
! 802: - gzread no longer reads one extra byte in certain cases
! 803: - In gzio destroy(), don't reference a freed structure
! 804: - avoid many warnings for MSDOS
! 805: - avoid the ERROR symbol which is used by MS Windows
! 806:
! 807: Changes in 0.71 (14 April 95)

! 809: TurboC large model.
! 810:
! 811: Changes in 0.7 (14 April 95)
! 812: - Added full inflate support.
! 813: - Simplified the crc32() interface. The pre- and post-conditioning
! 814: (one's complement) is now done inside crc32(). WARNING: this is
! 815: incompatible with previous versions; see zlib.h for the new usage.
! 816:
! 817: Changes in 0.61 (12 April 95)
! 818: - workaround for a bug in TurboC. example and minigzip now work on MSDOS.
! 819:
! 820: Changes in 0.6 (11 April 95)

! 825: - fixed bug in destroy (gzio.c) (don't return Z_STREAM_END for gzclose).
! 826: - don't allocate big arrays in the stack (for MSDOS)
! 827: - fix some MSDOS compilation problems
! 828:
! 829: Changes in 0.5:
! 830: - do real compression in deflate.c. Z_PARTIAL_FLUSH is supported but
! 831: not yet Z_FULL_FLUSH.
! 832: - support decompression but only in a single step (forced Z_FINISH)
! 833: - added opaque object for zalloc and zfree.
! 834: - added deflateReset and inflateReset
! 835: - added a variable zlib_version for consistency checking.
! 836: - renamed the 'filter' parameter of deflateInit2 as 'strategy'.
! 837: Added Z_FILTERED and Z_HUFFMAN_ONLY constants.
! 838:
! 839: Changes in 0.4:
! 840: - avoid "zip" everywhere, use zlib instead of ziplib.
! 841: - suppress Z_BLOCK_FLUSH, interpret Z_PARTIAL_FLUSH as block flush
! 842: if compression method == 8.
! 843: - added adler32 and crc32
! 844: - renamed deflateOptions as deflateInit2, call one or the other but not both
! 845: - added the method parameter for deflateInit2.
! 846: - added inflateInit2
! 847: - simplied considerably deflateInit and inflateInit by not supporting
! 848: user-provided history buffer. This is supported only in deflateInit2
! 849: and inflateInit2.
! 850:
! 851: Changes in 0.3:
! 852: - prefix all macro names with Z_
! 853: - use Z_FINISH instead of deflateEnd to finish compression.
! 854: - added Z_HUFFMAN_ONLY
! 855: - added gzerror()
