- 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()
