738 - added a dimension to all arrays (Borland C can't count). | |
739 - workaround Borland C bug in declaration of inflate_codes_new & inflate_fast | |
740 - guard against multiple inclusion of *.h (for precompiled header on Mac) | |
741 - Watcom C pretends to be Microsoft C small model even in 32 bit mode. | |
742 - don't use unsized arrays to avoid silly warnings by Visual C++: | |
743 warning C4746: 'inflate_mask' : unsized array treated as '__far' | |
744 (what's wrong with far data in far model?). | |
745 - define enum out of inflate_blocks_state to allow compilation with C++ | |
746 | |
747 Changes in 0.95 (16 Aug 95) | |
748 - fix MSDOS small and medium model (now easier to adapt to any compiler) | |
749 - inlined send_bits | |
750 - fix the final (:-) bug for deflate with flush (output was correct but | |
751 not completely flushed in rare occasions). | |
752 - default window size is same for compression and decompression | |
753 (it's now sufficient to set MAX_WBITS in zconf.h). | |
754 - voidp -> voidpf and voidnp -> voidp (for consistency with other | |
755 typedefs and because voidnp was not near in large model). | |
756 | |
757 Changes in 0.94 (13 Aug 95) | |
758 - support MSDOS medium model | |
759 - fix deflate with flush (could sometimes generate bad output) | |
760 - fix deflateReset (zlib header was incorrectly suppressed) | |
761 - added support for VMS | |
762 - allow a compression level in gzopen() | |
763 - gzflush now calls fflush | |
764 - For deflate with flush, flush even if no more input is provided. | |
765 - rename libgz.a as libz.a | |
766 - avoid complex expression in infcodes.c triggering Turbo C bug | |
767 - work around a problem with gcc on Alpha (in INSERT_STRING) | |
768 - don't use inline functions (problem with some gcc versions) | |
769 - allow renaming of Byte, uInt, etc... with #define. | |
770 - avoid warning about (unused) pointer before start of array in deflate.c | |
771 - avoid various warnings in gzio.c, example.c, infblock.c, adler32.c, zutil.c | |
772 - avoid reserved word 'new' in trees.c | |
773 | |
774 Changes in 0.93 (25 June 95) | |
775 - temporarily disable inline functions | |
776 - make deflate deterministic | |
777 - give enough lookahead for PARTIAL_FLUSH | |
778 - Set binary mode for stdin/stdout in minigzip.c for OS/2 | |
779 - don't even use signed char in inflate (not portable enough) | |
780 - fix inflate memory leak for segmented architectures | |
781 | |
782 Changes in 0.92 (3 May 95) | |
783 - don't assume that char is signed (problem on SGI) | |
784 - Clear bit buffer when starting a stored block | |
785 - no memcpy on Pyramid | |
786 - suppressed inftest.c | |
787 - optimized fill_window, put longest_match inline for gcc | |
788 - optimized inflate on stored blocks. | |
789 - untabify all sources to simplify patches | |
790 | |
791 Changes in 0.91 (2 May 95) | |
792 - Default MEM_LEVEL is 8 (not 9 for Unix) as documented in zlib.h | |
793 - Document the memory requirements in zconf.h | |
794 - added "make install" | |
795 - fix sync search logic in inflateSync | |
796 - deflate(Z_FULL_FLUSH) now works even if output buffer too short | |
797 - after inflateSync, don't scare people with just "lo world" | |
798 - added support for DJGPP | |
799 | |
800 Changes in 0.9 (1 May 95) | |
801 - don't assume that zalloc clears the allocated memory (the TurboC bug | |
802 was Mark's bug after all :) | |
803 - let again gzread copy uncompressed data unchanged (was working in 0.71) | |
804 - deflate(Z_FULL_FLUSH), inflateReset and inflateSync are now fully implemented | |
805 - added a test of inflateSync in example.c | |
806 - moved MAX_WBITS to zconf.h because users might want to change that. | |
807 - document explicitly that zalloc(64K) on MSDOS must return a normalized | |
808 pointer (zero offset) | |
809 - added Makefiles for Microsoft C, Turbo C, Borland C++ | |
810 - faster crc32() | |
811 | |
812 Changes in 0.8 (29 April 95) | |
813 - added fast inflate (inffast.c) | |
814 - deflate(Z_FINISH) now returns Z_STREAM_END when done. Warning: this | |
815 is incompatible with previous versions of zlib which returned Z_OK. | |
816 - work around a TurboC compiler bug (bad code for b << 0, see infutil.h) | |
817 (actually that was not a compiler bug, see 0.81 above) | |
818 - gzread no longer reads one extra byte in certain cases | |
819 - In gzio destroy(), don't reference a freed structure | |
820 - avoid many warnings for MSDOS | |
821 - avoid the ERROR symbol which is used by MS Windows | |
822 | |
823 Changes in 0.71 (14 April 95) | |
824 - Fixed more MSDOS compilation problems :( There is still a bug with | |
825 TurboC large model. | |
826 | |
827 Changes in 0.7 (14 April 95) | |
828 - Added full inflate support. | |
829 - Simplified the crc32() interface. The pre- and post-conditioning | |
830 (one's complement) is now done inside crc32(). WARNING: this is | |
831 incompatible with previous versions; see zlib.h for the new usage. | |
832 | |
833 Changes in 0.61 (12 April 95) | |
834 - workaround for a bug in TurboC. example and minigzip now work on MSDOS. | |
835 | |
836 Changes in 0.6 (11 April 95) | |
837 - added minigzip.c | |
838 - added gzdopen to reopen a file descriptor as gzFile | |
839 - added transparent reading of non-gziped files in gzread. | |
840 - fixed bug in gzread (don't read crc as data) | |
841 - fixed bug in destroy (gzio.c) (don't return Z_STREAM_END for gzclose). | |
842 - don't allocate big arrays in the stack (for MSDOS) | |
843 - fix some MSDOS compilation problems | |
844 | |
845 Changes in 0.5: | |
846 - do real compression in deflate.c. Z_PARTIAL_FLUSH is supported but | |
847 not yet Z_FULL_FLUSH. | |
848 - support decompression but only in a single step (forced Z_FINISH) | |
849 - added opaque object for zalloc and zfree. | |
850 - added deflateReset and inflateReset | |
851 - added a variable zlib_version for consistency checking. | |
852 - renamed the 'filter' parameter of deflateInit2 as 'strategy'. | |
853 Added Z_FILTERED and Z_HUFFMAN_ONLY constants. | |
854 | |
855 Changes in 0.4: | |
856 - avoid "zip" everywhere, use zlib instead of ziplib. | |
857 - suppress Z_BLOCK_FLUSH, interpret Z_PARTIAL_FLUSH as block flush | |
858 if compression method == 8. | |
859 - added adler32 and crc32 | |
860 - renamed deflateOptions as deflateInit2, call one or the other but not both | |
861 - added the method parameter for deflateInit2. | |
862 - added inflateInit2 | |
863 - simplied considerably deflateInit and inflateInit by not supporting | |
864 user-provided history buffer. This is supported only in deflateInit2 | |
865 and inflateInit2. | |
866 | |
867 Changes in 0.3: | |
868 - prefix all macro names with Z_ | |
869 - use Z_FINISH instead of deflateEnd to finish compression. | |
870 - added Z_HUFFMAN_ONLY | |
871 - added gzerror() |
