|
|
6 - no memcpy on Pyramid
|
|

|
12 Changes in 0.91 (2 May 95)
|
|
|
13 - Default MEM_LEVEL is 8 (not 9 for Unix) as documented in zlib.h
|
|
|
14 - Document the memory requirements in zconf.h
|
|
|
15 - added "make install"
|
|
|
16 - fix sync search logic in inflateSync
|
|
|
17 - deflate(Z_FULL_FLUSH) now works even if output buffer too short
|
|
|
18 - after inflateSync, don't scare people with just "lo world"
|

|
19 - added support for DJGPP
|
|
|

|
|
|
21 Changes in 0.9 (1 May 95)
|
|
|
22 - don't assume that zalloc clears the allocated memory (the TurboC bug
|
|
|
23 was Mark's bug after all :)
|
|
|
24 - let again gzread copy uncompressed data unchanged (was working in 0.71)
|
|
|
25 - deflate(Z_FULL_FLUSH), inflateReset and inflateSync are now fully implemented
|
|
|
26 - added a test of inflateSync in example.c
|
|
|
27 - moved MAX_WBITS to zconf.h because users might want to change that.
|
|
|
28 - document explicitly that zalloc(64K) on MSDOS must return a normalized
|
|
|
29 pointer (zero offset)
|
|
|
30 - added Makefiles for Microsoft C, Turbo C, Borland C++
|
|
|
31 - faster crc32()
|
|
|
32
|
|
|
33 Changes in 0.8 (29 April 95)
|
|
|
34 - added fast inflate (inffast.c)
|
|
|
35 - deflate(Z_FINISH) now returns Z_STREAM_END when done. Warning: this
|
|
|
36 is incompatible with previous versions of zlib which returned Z_OK.
|
|
|
37 - work around a TurboC compiler bug (bad code for b << 0, see infutil.h)
|
|
|
38 (actually that was not a compiler bug, see 0.81 above)
|
|
|
39 - gzread no longer reads one extra byte in certain cases
|
|
|
40 - In gzio destroy(), don't reference a freed structure
|
|
|
41 - avoid many warnings for MSDOS
|
|
|
42 - avoid the ERROR symbol which is used by MS Windows
|
|
|
43
|
|
|
44 Changes in 0.71 (14 April 95)
|
|
|
45 - Fixed more MSDOS compilation problems :( There is still a bug with
|
|
|
46 TurboC large model.
|
|
|
47
|
|
|
48 Changes in 0.7 (14 April 95)
|
|
|
49 - Added full inflate support.
|
|
|
50 - Simplified the crc32() interface. The pre- and post-conditioning
|
|
|
51 (one's complement) is now done inside crc32(). WARNING: this is
|
|
|
52 incompatible with previous versions; see zlib.h for the new usage.
|
|
|
53
|
|
|
54 Changes in 0.61 (12 April 95)

|
|
57 Changes in 0.6 (11 April 95)
|
|
|
58 - added minigzip.c
|
|
|
59 - added gzdopen to reopen a file descriptor as gzFile
|
|
|
60 - added transparent reading of non-gziped files in gzread.
|
|
|
61 - fixed bug in gzread (don't read crc as data)
|
|
|

|
|
|
63 - don't allocate big arrays in the stack (for MSDOS)
|
|
|
64 - fix some MSDOS compilation problems
|
|
|
65
|
|
|
66 Changes in 0.5:
|
|
|
67 - do real compression in deflate.c. Z_PARTIAL_FLUSH is supported but
|
|
|
68 not yet Z_FULL_FLUSH.
|
|
|
69 - support decompression but only in a single step (forced Z_FINISH)
|
|
|
70 - added opaque object for zalloc and zfree.
|
|
|
71 - added deflateReset and inflateReset
|
|
|
72 - added a variable zlib_version for consistency checking.
|
|
|
73 - renamed the 'filter' parameter of deflateInit2 as 'strategy'.
|
|
|
74 Added Z_FILTERED and Z_HUFFMAN_ONLY constants.
|
|
|
75
|
|
|
76 Changes in 0.4:
|
|
|
77 - avoid "zip" everywhere, use zlib instead of ziplib.
|
|
|
78 - suppress Z_BLOCK_FLUSH, interpret Z_PARTIAL_FLUSH as block flush
|
|
|
79 if compression method == 8.
|
|
|
80 - added adler32 and crc32
|
|
|
81 - renamed deflateOptions as deflateInit2, call one or the other but not both
|
|
|
82 - added the method parameter for deflateInit2.
|
|
|
83 - added inflateInit2
|
|
|
84 - simplied considerably deflateInit and inflateInit by not supporting
|
|
|
85 user-provided history buffer. This is supported only in deflateInit2
|
|
|
86 and inflateInit2.
|
|
|
87
|
|
|
88 Changes in 0.3:
|
|
|
89 - prefix all macro names with Z_
|
|
|
90 - use Z_FINISH instead of deflateEnd to finish compression.
|
|
|
91 - added Z_HUFFMAN_ONLY
|
|
|
92 - added gzerror()
