Warning: this cannam@128: is incompatible with previous versions of zlib which returned Z_OK. cannam@128: - work around a TurboC compiler bug (bad code for b << 0, see infutil.h) cannam@128: (actually that was not a compiler bug, see 0.81 above) cannam@128: - gzread no longer reads one extra byte in certain cases cannam@128: - In gzio destroy(), don't reference a freed structure cannam@128: - avoid many warnings for MSDOS cannam@128: - avoid the ERROR symbol which is used by MS Windows cannam@128: cannam@128: Changes in 0.71 (14 April 95) cannam@128: - Fixed more MSDOS compilation problems :( There is still a bug with cannam@128: TurboC large model. cannam@128: cannam@128: Changes in 0.7 (14 April 95) cannam@128: - Added full inflate support. cannam@128: - Simplified the crc32() interface. The pre- and post-conditioning cannam@128: (one's complement) is now done inside crc32(). WARNING: this is cannam@128: incompatible with previous versions; see zlib.h for the new usage. cannam@128: cannam@128: Changes in 0.61 (12 April 95) cannam@128: - workaround for a bug in TurboC. example and minigzip now work on MSDOS. cannam@128: cannam@128: Changes in 0.6 (11 April 95) cannam@128: - added minigzip.c cannam@128: - added gzdopen to reopen a file descriptor as gzFile cannam@128: - added transparent reading of non-gziped files in gzread. cannam@128: - fixed bug in gzread (don't read crc as data) cannam@128: - fixed bug in destroy (gzio.c) (don't return Z_STREAM_END for gzclose). cannam@128: - don't allocate big arrays in the stack (for MSDOS) cannam@128: - fix some MSDOS compilation problems cannam@128: cannam@128: Changes in 0.5: cannam@128: - do real compression in deflate.c. Z_PARTIAL_FLUSH is supported but cannam@128: not yet Z_FULL_FLUSH. cannam@128: - support decompression but only in a single step (forced Z_FINISH) cannam@128: - added opaque object for zalloc and zfree. cannam@128: - added deflateReset and inflateReset cannam@128: - added a variable zlib_version for consistency checking. cannam@128: - renamed the 'filter' parameter of deflateInit2 as 'strategy'. cannam@128: Added Z_FILTERED and Z_HUFFMAN_ONLY constants. cannam@128: cannam@128: Changes in 0.4: cannam@128: - avoid "zip" everywhere, use zlib instead of ziplib. cannam@128: - suppress Z_BLOCK_FLUSH, interpret Z_PARTIAL_FLUSH as block flush cannam@128: if compression method == 8. cannam@128: - added adler32 and crc32 cannam@128: - renamed deflateOptions as deflateInit2, call one or the other but not both cannam@128: - added the method parameter for deflateInit2. cannam@128: - added inflateInit2 cannam@128: - simplied considerably deflateInit and inflateInit by not supporting cannam@128: user-provided history buffer. This is supported only in deflateInit2 cannam@128: and inflateInit2. cannam@128: cannam@128: Changes in 0.3: cannam@128: - prefix all macro names with Z_ cannam@128: - use Z_FINISH instead of deflateEnd to finish compression. cannam@128: - added Z_HUFFMAN_ONLY cannam@128: - added gzerror()
