|
|
- remove block truncation heuristic which had very marginal effect for zlib
|

|
|
Changes in 1.0.4 (24 Jul 96)
|
|
- In very rare conditions, deflate(s, Z_FINISH) could fail to produce an EOF
|
|
bit, so the decompressor could decompress all the correct data but went
|
|
on to attempt decompressing extra garbage data. This affected minigzip too.
|
|
- zlibVersion and gzerror return const char* (needed for DLL)

|
|
Changes in 1.0.3 (2 Jul 96)
|
|
- use z_streamp instead of z_stream *, which is now a far pointer in MSDOS
|
|
small and medium models; this makes the library incompatible with previous
|
|
versions for these models. (No effect in large model or on other systems.)
|
|
- return OK instead of BUF_ERROR if previous deflate call returned with
|
|
avail_out as zero but there is nothing to do
|
|
- added memcmp for non STDC compilers

|
|
- added Windows DLL support
|
|
- added a function zlibVersion (for the DLL support)

|
|
- Bytef is define's instead of typedef'd only for Borland C
|

|
|

|
|
- guard against multiple inclusion of *.h (for precompiled header on Mac)
|
|
- Watcom C pretends to be Microsoft C small model even in 32 bit mode.
|
|
- don't use unsized arrays to avoid silly warnings by Visual C++:
|
|
warning C4746: 'inflate_mask' : unsized array treated as '__far'

|
|
- fix the final (:-) bug for deflate with flush (output was correct but
|
|
not completely flushed in rare occasions).
|
|
- default window size is same for compression and decompression
|
|
(it's now sufficient to set MAX_WBITS in zconf.h).
|
|
- voidp -> voidpf and voidnp -> voidp (for consistency with other
|
|
typedefs and because voidnp was not near in large model).
|
|

|
Changes in 0.9 (1 May 95)

|
|
was Mark's bug after all :)
|
|
- let again gzread copy uncompressed data unchanged (was working in 0.71)
|
|
- deflate(Z_FULL_FLUSH), inflateReset and inflateSync are now fully implemented

|
|
(actually that was not a compiler bug, see 0.81 above)
|
|

|
|
- Simplified the crc32() interface. The pre- and post-conditioning
|
|
(one's complement) is now done inside crc32(). WARNING: this is
|
|
incompatible with previous versions; see zlib.h for the new usage.

|
Changes in 0.6 (11 April 95)
|
|
- added minigzip.c
|
|
- added gzdopen to reopen a file descriptor as gzFile
|
|
- added transparent reading of non-gziped files in gzread.
|
|
- fixed bug in gzread (don't read crc as data)
|
|
- fixed bug in destroy (gzio.c) (don't return Z_STREAM_END for gzclose).
|
|
- don't allocate big arrays in the stack (for MSDOS)
|
|
- fix some MSDOS compilation problems
|
|
|
|
Changes in 0.5:
|
|
- do real compression in deflate.c. Z_PARTIAL_FLUSH is supported but
|
|
not yet Z_FULL_FLUSH.
|
|
- support decompression but only in a single step (forced Z_FINISH)
|
|
- added opaque object for zalloc and zfree.
|
|
- added deflateReset and inflateReset
|
|
- added a variable zlib_version for consistency checking.
|
|
- renamed the 'filter' parameter of deflateInit2 as 'strategy'.
|
|
Added Z_FILTERED and Z_HUFFMAN_ONLY constants.
|
|
|
|
Changes in 0.4:
|
|
- avoid "zip" everywhere, use zlib instead of ziplib.
|
|
- suppress Z_BLOCK_FLUSH, interpret Z_PARTIAL_FLUSH as block flush
|
|
if compression method == 8.
|
|
- added adler32 and crc32
|
|
- renamed deflateOptions as deflateInit2, call one or the other but not both
|
|
- added the method parameter for deflateInit2.
|
|
- added inflateInit2
|
|
- simplied considerably deflateInit and inflateInit by not supporting
|
|
user-provided history buffer. This is supported only in deflateInit2
|
|
and inflateInit2.
|
|
|
|
Changes in 0.3:
|
|
- prefix all macro names with Z_
|
|
- use Z_FINISH instead of deflateEnd to finish compression.

|
- added Z_HUFFMAN_ONLY
|
|
- added gzerror()
