Chris@4: - workaround Borland C bug in declaration of inflate_codes_new & inflate_fast Chris@4: - guard against multiple inclusion of *.h (for precompiled header on Mac) Chris@4: - Watcom C pretends to be Microsoft C small model even in 32 bit mode. Chris@4: - don't use unsized arrays to avoid silly warnings by Visual C++: Chris@4: warning C4746: 'inflate_mask' : unsized array treated as '__far' Chris@4: (what's wrong with far data in far model?). Chris@4: - define enum out of inflate_blocks_state to allow compilation with C++ Chris@4: Chris@4: Changes in 0.95 (16 Aug 95) Chris@4: - fix MSDOS small and medium model (now easier to adapt to any compiler) Chris@4: - inlined send_bits Chris@4: - fix the final (:-) bug for deflate with flush (output was correct but Chris@4: not completely flushed in rare occasions). Chris@4: - default window size is same for compression and decompression Chris@4: (it's now sufficient to set MAX_WBITS in zconf.h). Chris@4: - voidp -> voidpf and voidnp -> voidp (for consistency with other Chris@4: typedefs and because voidnp was not near in large model). Chris@4: Chris@4: Changes in 0.94 (13 Aug 95) Chris@4: - support MSDOS medium model Chris@4: - fix deflate with flush (could sometimes generate bad output) Chris@4: - fix deflateReset (zlib header was incorrectly suppressed) Chris@4: - added support for VMS Chris@4: - allow a compression level in gzopen() Chris@4: - gzflush now calls fflush Chris@4: - For deflate with flush, flush even if no more input is provided. Chris@4: - rename libgz.a as libz.a Chris@4: - avoid complex expression in infcodes.c triggering Turbo C bug Chris@4: - work around a problem with gcc on Alpha (in INSERT_STRING) Chris@4: - don't use inline functions (problem with some gcc versions) Chris@4: - allow renaming of Byte, uInt, etc... with #define. Chris@4: - avoid warning about (unused) pointer before start of array in deflate.c Chris@4: - avoid various warnings in gzio.c, example.c, infblock.c, adler32.c, zutil.c Chris@4: - avoid reserved word 'new' in trees.c Chris@4: Chris@4: Changes in 0.93 (25 June 95) Chris@4: - temporarily disable inline functions Chris@4: - make deflate deterministic Chris@4: - give enough lookahead for PARTIAL_FLUSH Chris@4: - Set binary mode for stdin/stdout in minigzip.c for OS/2 Chris@4: - don't even use signed char in inflate (not portable enough) Chris@4: - fix inflate memory leak for segmented architectures Chris@4: Chris@4: Changes in 0.92 (3 May 95) Chris@4: - don't assume that char is signed (problem on SGI) Chris@4: - Clear bit buffer when starting a stored block Chris@4: - no memcpy on Pyramid Chris@4: - suppressed inftest.c Chris@4: - optimized fill_window, put longest_match inline for gcc Chris@4: - optimized inflate on stored blocks. Chris@4: - untabify all sources to simplify patches Chris@4: Chris@4: Changes in 0.91 (2 May 95) Chris@4: - Default MEM_LEVEL is 8 (not 9 for Unix) as documented in zlib.h Chris@4: - Document the memory requirements in zconf.h Chris@4: - added "make install" Chris@4: - fix sync search logic in inflateSync Chris@4: - deflate(Z_FULL_FLUSH) now works even if output buffer too short Chris@4: - after inflateSync, don't scare people with just "lo world" Chris@4: - added support for DJGPP Chris@4: Chris@4: Changes in 0.9 (1 May 95) Chris@4: - don't assume that zalloc clears the allocated memory (the TurboC bug Chris@4: was Mark's bug after all :) Chris@4: - let again gzread copy uncompressed data unchanged (was working in 0.71) Chris@4: - deflate(Z_FULL_FLUSH), inflateReset and inflateSync are now fully implemented Chris@4: - added a test of inflateSync in example.c Chris@4: - moved MAX_WBITS to zconf.h because users might want to change that. Chris@4: - document explicitly that zalloc(64K) on MSDOS must return a normalized Chris@4: pointer (zero offset) Chris@4: - added Makefiles for Microsoft C, Turbo C, Borland C++ Chris@4: - faster crc32() Chris@4: Chris@4: Changes in 0.8 (29 April 95) Chris@4: - added fast inflate (inffast.c) Chris@4: - deflate(Z_FINISH) now returns Z_STREAM_END when done. Warning: this Chris@4: is incompatible with previous versions of zlib which returned Z_OK. Chris@4: - work around a TurboC compiler bug (bad code for b << 0, see infutil.h) Chris@4: (actually that was not a compiler bug, see 0.81 above) Chris@4: - gzread no longer reads one extra byte in certain cases Chris@4: - In gzio destroy(), don't reference a freed structure Chris@4: - avoid many warnings for MSDOS Chris@4: - avoid the ERROR symbol which is used by MS Windows Chris@4: Chris@4: Changes in 0.71 (14 April 95) Chris@4: - Fixed more MSDOS compilation problems :( There is still a bug with Chris@4: TurboC large model. Chris@4: Chris@4: Changes in 0.7 (14 April 95) Chris@4: - Added full inflate support. Chris@4: - Simplified the crc32() interface. The pre- and post-conditioning Chris@4: (one's complement) is now done inside crc32(). WARNING: this is Chris@4: incompatible with previous versions; see zlib.h for the new usage. Chris@4: Chris@4: Changes in 0.61 (12 April 95) Chris@4: - workaround for a bug in TurboC. example and minigzip now work on MSDOS. Chris@4: Chris@4: Changes in 0.6 (11 April 95) Chris@4: - added minigzip.c Chris@4: - added gzdopen to reopen a file descriptor as gzFile Chris@4: - added transparent reading of non-gziped files in gzread. Chris@4: - fixed bug in gzread (don't read crc as data) Chris@4: - fixed bug in destroy (gzio.c) (don't return Z_STREAM_END for gzclose). Chris@4: - don't allocate big arrays in the stack (for MSDOS) Chris@4: - fix some MSDOS compilation problems Chris@4: Chris@4: Changes in 0.5: Chris@4: - do real compression in deflate.c. Z_PARTIAL_FLUSH is supported but Chris@4: not yet Z_FULL_FLUSH. Chris@4: - support decompression but only in a single step (forced Z_FINISH) Chris@4: - added opaque object for zalloc and zfree. Chris@4: - added deflateReset and inflateReset Chris@4: - added a variable zlib_version for consistency checking. Chris@4: - renamed the 'filter' parameter of deflateInit2 as 'strategy'. Chris@4: Added Z_FILTERED and Z_HUFFMAN_ONLY constants. Chris@4: Chris@4: Changes in 0.4: Chris@4: - avoid "zip" everywhere, use zlib instead of ziplib. Chris@4: - suppress Z_BLOCK_FLUSH, interpret Z_PARTIAL_FLUSH as block flush Chris@4: if compression method == 8. Chris@4: - added adler32 and crc32 Chris@4: - renamed deflateOptions as deflateInit2, call one or the other but not both Chris@4: - added the method parameter for deflateInit2. Chris@4: - added inflateInit2 Chris@4: - simplied considerably deflateInit and inflateInit by not supporting Chris@4: user-provided history buffer. This is supported only in deflateInit2 Chris@4: and inflateInit2. Chris@4: Chris@4: Changes in 0.3: Chris@4: - prefix all macro names with Z_ Chris@4: - use Z_FINISH instead of deflateEnd to finish compression. Chris@4: - added Z_HUFFMAN_ONLY Chris@4: - added gzerror()
