-The changes made in version 0.8 are documented in the file ChangeLog.
-The main changes since 0.71 are:
-- added fast inflate (inffast.c)
-- deflate(Z_FINISH) now returns Z_STREAM_END when done. Warning: this

-- work around a nasty TurboC compiler bug
+The changes made in version 0.9 are documented in the file ChangeLog.
+The main changes since 0.8 are:
+- don't assume that zalloc clears the allocated memory
+- let again gzread copy uncompressed data unchanged (was working in 0.71)
+- deflate(Z_FULL_FLUSH), inflateReset and inflateSync are now fully implemented
 
 On MSDOS, this version works in both large and small model. However
 small model compression works only for small values of MEM_LEVEL and
 WBITS (see zutil.h). Small model decompression should work up to WBITS=15.
