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

|
|
|
18 - added support for VMS
|
|
|
19 - allow a compression level in gzopen()

|
|
|
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

|
|
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)

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.
