- ChangeLog file for zlib
-
- 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++
-
- 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()
-
