|
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) |
|
- port to RISCOS (no fdopen, no multiple dots, no unlink, no fileno) |

|
|
|
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.) |
|

|
avail_out as zero but there is nothing to do |

|
- inlined send_bits |
|
- fix the final (:-) bug for deflate with flush (output was correct but |
|
not completely flushed in rare occasions). |
|

|
(it's now sufficient to set MAX_WBITS in zconf.h). |

|
- avoid reserved word 'new' in trees.c |
|
|
|
Changes in 0.93 (25 June 95) |
|
- temporarily disable inline functions |
|
- make deflate deterministic |
|
- give enough lookahead for PARTIAL_FLUSH |
|
- Set binary mode for stdin/stdout in minigzip.c for OS/2 |
|
- don't even use signed char in inflate (not portable enough) |
|
- fix inflate memory leak for segmented architectures |
|
|
|
Changes in 0.92 (3 May 95) |
|
- don't assume that char is signed (problem on SGI) |
|
- Clear bit buffer when starting a stored block |
|
- no memcpy on Pyramid |
|
- suppressed inftest.c |
|
- optimized fill_window, put longest_match inline for gcc |
|
- optimized inflate on stored blocks. |
|
- untabify all sources to simplify patches |
|
|
|
Changes in 0.91 (2 May 95) |
|
- Default MEM_LEVEL is 8 (not 9 for Unix) as documented in zlib.h |
|
- Document the memory requirements in zconf.h |
|
- added "make install" |
|
- fix sync search logic in inflateSync |
|
- deflate(Z_FULL_FLUSH) now works even if output buffer too short |
|
- after inflateSync, don't scare people with just "lo world" |
|
- added support for DJGPP |
|
|
|
Changes in 0.9 (1 May 95) |
|
- don't assume that zalloc clears the allocated memory (the TurboC bug |
|
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 |
|
- added a test of inflateSync in example.c |
|
- moved MAX_WBITS to zconf.h because users might want to change that. |
|
- document explicitly that zalloc(64K) on MSDOS must return a normalized |
|
pointer (zero offset) |
|
- added Makefiles for Microsoft C, Turbo C, Borland C++ |
|
- faster crc32() |
|
|
|
Changes in 0.8 (29 April 95) |
|
- added fast inflate (inffast.c) |
|
- deflate(Z_FINISH) now returns Z_STREAM_END when done. Warning: this |
|
is incompatible with previous versions of zlib which returned Z_OK. |
|
- work around a TurboC compiler bug (bad code for b << 0, see infutil.h) |
|
(actually that was not a compiler bug, see 0.81 above) |
|
- gzread no longer reads one extra byte in certain cases |
|
- In gzio destroy(), don't reference a freed structure |
|
- avoid many warnings for MSDOS |
|
- avoid the ERROR symbol which is used by MS Windows |
|
|
|
Changes in 0.71 (14 April 95) |
|
- Fixed more MSDOS compilation problems :( There is still a bug with |
|
TurboC large model. |
|
|
|
Changes in 0.7 (14 April 95) |
|
- Added full inflate support. |
|
- 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 0.61 (12 April 95) |
|
- workaround for a bug in TurboC. example and minigzip now work on MSDOS. |
|
|
|
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()
