-
|
|
|
-Changes in 1.2.0 (9 March 2003)
|
|
|
-- New and improved inflate code
|
|
|
- - About 20% faster
|
|
|
- - Does not allocate 32K window unless and until needed
|
|
|
- - Automatically detects and decompresses gzip streams
|
|
|
- - Raw inflate no longer needs an extra dummy byte at end
|
|
|
- - Added inflateBack functions using a callback interface--even faster
|
|
|
- than inflate, useful for file utilities (gzip, zip)
|
|
|
- - Added inflateCopy() function to record state for random access on
|
|
|
- externally generated deflate streams (e.g. in gzip files)
|
|
|
- - More readable code (I hope)
|
|
|
-- New and improved crc32()
|
|
|
- - About 50% faster, thanks to suggestions from Rodney Brown

|
-Changes in 1.0.4 (24 Jul 96)
|
|
|
-- In very rare conditions, deflate(s, Z_FINISH) could fail to produce an EOF
|
|
|
- bit, so the decompressor could decompress all the correct data but went
|
|
|
- on to attempt decompressing extra garbage data. This affected minigzip too.
|
|

|
|
|
- small and medium models; this makes the library incompatible with previous
|
|
|
- versions for these models. (No effect in large model or on other systems.)
