502 | (but the symbol Z_PARTIAL_FLUSH is kept for compatibility with 1.0.4) |

---|
504 | (this feature was not implemented anyway in 1.0.4) |

---|
571 | - In very rare conditions, deflate(s, Z_FINISH) could fail to produce an EOF |
---|
572 | bit, so the decompressor could decompress all the correct data but went |
---|
573 | on to attempt decompressing extra garbage data. This affected minigzip too. |
---|
574 | - zlibVersion and gzerror return const char* (needed for DLL) |
---|
575 | - port to RISCOS (no fdopen, no multiple dots, no unlink, no fileno) |

---|
579 | - use z_streamp instead of z_stream *, which is now a far pointer in MSDOS |

---|
608 | - speed up adler32 for modern machines without auto-increment |
---|
609 | - added -ansi for IRIX in configure |

---|
618 | - work around an MWKERKS bug (incorrect merge of all .h files) |
---|
619 | |

---|
622 | - allow compression level 0 (no compression) |

678 | (what's wrong with far data in far model?). |
---|
679 | - define enum out of inflate_blocks_state to allow compilation with C++ |
---|
680 | |

---|
685 | not completely flushed in rare occasions). |
---|
686 | - default window size is same for compression and decompression |
---|
687 | (it's now sufficient to set MAX_WBITS in zconf.h). |
---|
688 | - voidp -> voidpf and voidnp -> voidp (for consistency with other |
---|
689 | typedefs and because voidnp was not near in large model). |
---|
690 | |

726 | - Default MEM_LEVEL is 8 (not 9 for Unix) as documented in zlib.h |
---|
727 | - Document the memory requirements in zconf.h |
---|
728 | - added "make install" |
---|
729 | - fix sync search logic in inflateSync |
---|
730 | - deflate(Z_FULL_FLUSH) now works even if output buffer too short |

731 | - after inflateSync, don't scare people with just "lo world" |
---|
732 | - added support for DJGPP |
---|
733 | |
---|
734 | Changes in 0.9 (1 May 95) |

742 | pointer (zero offset) |
---|
743 | - added Makefiles for Microsoft C, Turbo C, Borland C++ |

---|
747 | - added fast inflate (inffast.c) |
---|
748 | - deflate(Z_FINISH) now returns Z_STREAM_END when done. Warning: this |
---|
749 | is incompatible with previous versions of zlib which returned Z_OK. |
---|
750 | - work around a TurboC compiler bug (bad code for b << 0, see infutil.h) |
---|
751 | (actually that was not a compiler bug, see 0.81 above) |

761 | Changes in 0.7 (14 April 95) |
---|
762 | - Added full inflate support. |
---|
763 | - Simplified the crc32() interface. The pre- and post-conditioning |

---|
765 | incompatible with previous versions; see zlib.h for the new usage. |
---|
766 | |
---|
767 | Changes in 0.61 (12 April 95) |

---|
771 | - added minigzip.c |
---|
772 | - added gzdopen to reopen a file descriptor as gzFile |

---|
777 | - fix some MSDOS compilation problems |
---|
778 | |
---|
779 | Changes in 0.5: |
---|
780 | - do real compression in deflate.c. Z_PARTIAL_FLUSH is supported but |
---|
781 | not yet Z_FULL_FLUSH. |

784 | - added deflateReset and inflateReset |
---|
785 | - added a variable zlib_version for consistency checking. |
---|

---|
787 | Added Z_FILTERED and Z_HUFFMAN_ONLY constants. |
---|
788 | |
---|
789 | Changes in 0.4: |
---|
790 | - avoid "zip" everywhere, use zlib instead of ziplib. |
---|
791 | - suppress Z_BLOCK_FLUSH, interpret Z_PARTIAL_FLUSH as block flush |
---|
792 | if compression method == 8. |
---|
793 | - added adler32 and crc32 |
---|
794 | - renamed deflateOptions as deflateInit2, call one or the other but not both |
---|
795 | - added the method parameter for deflateInit2. |
---|
796 | - added inflateInit2 |
---|
797 | - simplied considerably deflateInit and inflateInit by not supporting |
---|
798 | user-provided history buffer. This is supported only in deflateInit2 |
---|
799 | and inflateInit2. |
---|
800 | |
---|
801 | Changes in 0.3: |
---|
802 | - prefix all macro names with Z_ |
---|
803 | - use Z_FINISH instead of deflateEnd to finish compression. |
---|
804 | - added Z_HUFFMAN_ONLY |
---|
805 | - added gzerror() |
---|
