+ − 3
+ − 4 Changes in 0.95 (16 Aug 95)
+ − 5 - fix MSDOS small and medium model (now easier to adapt to any compiler)
+ − 6 - inlined send_bits
+ − 7 - fix the final (:-) bug for deflate with flush (output was correct but
+ − 8 not completely flushed in rare occasions).
+ − 9 - default window size is same for compression and decompression
+ − 10 (it's now sufficient to set MAX_WBITS in zconf.h).
+ − 11 - voidp -> voidpf and voidnp -> voidp (for consistency with other
+ − 12 typedefs and because voidnp was not near in large model).
+ − 13
+ − 14 Changes in 0.94 (13 Aug 95)
+ − 15 - support MSDOS medium model
+ − 16 - fix deflate with flush (could sometimes generate bad output)

+ − 18 - added support for VMS
+ − 19 - allow a compression level in gzopen()
+ − 20 - gzflush now calls fflush
+ − 21 - For deflate with flush, flush even if no more input is provided.

+ − 33 - make deflate deterministic
+ − 34 - give enough lookahead for PARTIAL_FLUSH
+ − 35 - Set binary mode for stdin/stdout in minigzip.c for OS/2
+ − 36 - don't even use signed char in inflate (not portable enough)
+ − 37 - fix inflate memory leak for segmented architectures
+ − 38
+ − 39 Changes in 0.92 (3 May 95)
+ − 40 - don't assume that char is signed (problem on SGI)
+ − 41 - Clear bit buffer when starting a stored block
+ − 42 - no memcpy on Pyramid
+ − 43 - suppressed inftest.c

+ − 45 - optimized inflate on stored blocks.
+ − 46 - untabify all sources to simplify patches
+ − 47
+ − 48 Changes in 0.91 (2 May 95)
+ − 49 - Default MEM_LEVEL is 8 (not 9 for Unix) as documented in zlib.h
+ − 50 - Document the memory requirements in zconf.h
+ − 51 - added "make install"
+ − 52 - fix sync search logic in inflateSync
+ − 53 - deflate(Z_FULL_FLUSH) now works even if output buffer too short
+ − 54 - after inflateSync, don't scare people with just "lo world"
+ − 55 - added support for DJGPP
+ − 56
+ − 57 Changes in 0.9 (1 May 95)
+ − 58 - don't assume that zalloc clears the allocated memory (the TurboC bug
+ − 59 was Mark's bug after all :)
+ − 60 - let again gzread copy uncompressed data unchanged (was working in 0.71)
+ − 61 - deflate(Z_FULL_FLUSH), inflateReset and inflateSync are now fully implemented
+ − 62 - added a test of inflateSync in example.c
+ − 63 - moved MAX_WBITS to zconf.h because users might want to change that.
+ − 64 - document explicitly that zalloc(64K) on MSDOS must return a normalized
+ − 65 pointer (zero offset)
+ − 66 - added Makefiles for Microsoft C, Turbo C, Borland C++
+ − 67 - faster crc32()
+ − 68
+ − 69 Changes in 0.8 (29 April 95)
+ − 70 - added fast inflate (inffast.c)
+ − 71 - deflate(Z_FINISH) now returns Z_STREAM_END when done. Warning: this
+ − 72 is incompatible with previous versions of zlib which returned Z_OK.
+ − 73 - work around a TurboC compiler bug (bad code for b << 0, see infutil.h)
+ − 74 (actually that was not a compiler bug, see 0.81 above)
+ − 75 - gzread no longer reads one extra byte in certain cases
+ − 76 - In gzio destroy(), don't reference a freed structure
+ − 77 - avoid many warnings for MSDOS
+ − 78 - avoid the ERROR symbol which is used by MS Windows
+ − 79
+ − 80 Changes in 0.71 (14 April 95)
+ − 81 - Fixed more MSDOS compilation problems :( There is still a bug with
+ − 82 TurboC large model.
+ − 83
+ − 84 Changes in 0.7 (14 April 95)
+ − 85 - Added full inflate support.
+ − 86 - Simplified the crc32() interface. The pre- and post-conditioning
+ − 87 (one's complement) is now done inside crc32(). WARNING: this is
+ − 88 incompatible with previous versions; see zlib.h for the new usage.
+ − 89
+ − 90 Changes in 0.61 (12 April 95)
+ − 91 - workaround for a bug in TurboC. example and minigzip now work on MSDOS.
+ − 92
+ − 93 Changes in 0.6 (11 April 95)
+ − 94 - added minigzip.c
+ − 95 - added gzdopen to reopen a file descriptor as gzFile
+ − 96 - added transparent reading of non-gziped files in gzread.
+ − 97 - fixed bug in gzread (don't read crc as data)
+ − 98 - fixed bug in destroy (gzio.c) (don't return Z_STREAM_END for gzclose).
+ − 99 - don't allocate big arrays in the stack (for MSDOS)
+ − 100 - fix some MSDOS compilation problems
+ − 101
+ − 102 Changes in 0.5:
+ − 103 - do real compression in deflate.c. Z_PARTIAL_FLUSH is supported but
+ − 104 not yet Z_FULL_FLUSH.
+ − 105 - support decompression but only in a single step (forced Z_FINISH)
+ − 106 - added opaque object for zalloc and zfree.
+ − 107 - added deflateReset and inflateReset
+ − 108 - added a variable zlib_version for consistency checking.
+ − 109 - renamed the 'filter' parameter of deflateInit2 as 'strategy'.
+ − 110 Added Z_FILTERED and Z_HUFFMAN_ONLY constants.
+ − 111
+ − 112 Changes in 0.4:
+ − 113 - avoid "zip" everywhere, use zlib instead of ziplib.
+ − 114 - suppress Z_BLOCK_FLUSH, interpret Z_PARTIAL_FLUSH as block flush
+ − 115 if compression method == 8.
+ − 116 - added adler32 and crc32
+ − 117 - renamed deflateOptions as deflateInit2, call one or the other but not both
+ − 118 - added the method parameter for deflateInit2.
+ − 119 - added inflateInit2
+ − 120 - simplied considerably deflateInit and inflateInit by not supporting
+ − 121 user-provided history buffer. This is supported only in deflateInit2
+ − 122 and inflateInit2.
+ − 123
+ − 124 Changes in 0.3:
+ − 125 - prefix all macro names with Z_
+ − 126 - use Z_FINISH instead of deflateEnd to finish compression.
+ − 127 - added Z_HUFFMAN_ONLY
+ − 128 - added gzerror()
