zlib 0.8 is a beta version of a general purpose compression library.
This is the first version with no known bugs. (There may still be
problem on SGI, to be checked.)
The data format used by the zlib library is described in the
file zlib-3.1.doc, deflate-1.1.doc and gzip-4.1.doc, available

The changes made in version 0.79 are documented in the file ChangeLog.
The changes made in version 0.8 are documented in the file ChangeLog.
The main changes since 0.71 are:
- add fast inflate (inffast.c)
- In gzio destroy(), don't reference a freed structure
- added fast inflate (inffast.c)
- deflate(Z_FINISH) now returns Z_STREAM_END when done. Warning: this
is incompatible with previous versions of zlib which returned Z_OK.
- work around a nasty TurboC compiler bug
On MSDOS, this version works in large and small model with MSC; in
small model only with TurboC (bug being investigated). For both
compilers, small model compression works only for small values of
MEM_LEVEL and WBITS (see zutil.h), and requires -DUSE_CALLOC.
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.
This version of zlib does not yet support small or medium model with
far allocation of big objects.
