1.1355 + not completely flushed in rare occasions).
1.1356 +- default window size is same for compression and decompression
1.1357 + (it's now sufficient to set MAX_WBITS in zconf.h).
1.1358 +- voidp -> voidpf and voidnp -> voidp (for consistency with other

1.1403 +
1.1404 +Changes in 0.9 (1 May 95)

1.1431 +Changes in 0.7 (14 April 95)
1.1432 +- Added full inflate support.
1.1433 +- Simplified the crc32() interface. The pre- and post-conditioning
1.1434 + (one's complement) is now done inside crc32(). WARNING: this is
1.1435 + incompatible with previous versions; see zlib.h for the new usage.
1.1436 +
1.1437 +Changes in 0.61 (12 April 95)
1.1438 +- workaround for a bug in TurboC. example and minigzip now work on MSDOS.
1.1439 +
1.1440 +Changes in 0.6 (11 April 95)
1.1441 +- added minigzip.c
1.1442 +- added gzdopen to reopen a file descriptor as gzFile
1.1443 +- added transparent reading of non-gziped files in gzread.
1.1444 +- fixed bug in gzread (don't read crc as data)
1.1445 +- fixed bug in destroy (gzio.c) (don't return Z_STREAM_END for gzclose).
1.1446 +- don't allocate big arrays in the stack (for MSDOS)
1.1447 +- fix some MSDOS compilation problems
1.1448 +
1.1449 +Changes in 0.5:
1.1450 +- do real compression in deflate.c. Z_PARTIAL_FLUSH is supported but
1.1451 + not yet Z_FULL_FLUSH.
1.1452 +- support decompression but only in a single step (forced Z_FINISH)
1.1453 +- added opaque object for zalloc and zfree.
1.1454 +- added deflateReset and inflateReset
1.1455 +- added a variable zlib_version for consistency checking.
1.1456 +- renamed the 'filter' parameter of deflateInit2 as 'strategy'.
1.1457 + Added Z_FILTERED and Z_HUFFMAN_ONLY constants.
1.1458 +
1.1459 +Changes in 0.4:
1.1460 +- avoid "zip" everywhere, use zlib instead of ziplib.
1.1461 +- suppress Z_BLOCK_FLUSH, interpret Z_PARTIAL_FLUSH as block flush
1.1462 + if compression method == 8.
1.1463 +- added adler32 and crc32
1.1464 +- renamed deflateOptions as deflateInit2, call one or the other but not both
1.1465 +- added the method parameter for deflateInit2.
1.1466 +- added inflateInit2
1.1467 +- simplied considerably deflateInit and inflateInit by not supporting
1.1468 + user-provided history buffer. This is supported only in deflateInit2
1.1469 + and inflateInit2.
1.1470 +
1.1471 +Changes in 0.3:
1.1472 +- prefix all macro names with Z_
1.1473 +- use Z_FINISH instead of deflateEnd to finish compression.
1.1474 +- added Z_HUFFMAN_ONLY
1.1475 +- added gzerror()
