| ChangeLog file for zlib |
| |
| Changes in 0.95 (16 Aug 95) |
| - fix MSDOS small and medium model (now easier to adapt to any compiler) |
| - inlined send_bits |
| - 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 0.94 (13 Aug 95) |
| - support MSDOS medium model |
| - fix deflate with flush (could sometimes generate bad output) |
| - fix deflateReset (zlib header was incorrectly suppressed) |
| - added support for VMS |
| - allow a compression level in gzopen() |
| - gzflush now calls fflush |
| - For deflate with flush, flush even if no more input is provided. |
| - rename libgz.a as libz.a |
| - avoid complex expression in infcodes.c triggering Turbo C bug |
| - work around a problem with gcc on Alpha (in INSERT_STRING) |
| - don't use inline functions (problem with some gcc versions) |
| - allow renaming of Byte, uInt, etc... with #define. |
| - avoid warning about (unused) pointer before start of array in deflate.c |
| - avoid various warnings in gzio.c, example.c, infblock.c, adler32.c, zutil.c |
| - 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() |
