zlib 0.94 is a beta version of a general purpose compression library.
Unless new bugs are found it will be released again as the first official
version (1.0). This version has no known bugs.
zlib 0.95 is a beta version of a general purpose compression library.
This should be the last version before the first official
version (1.0), so please test it now. (At least compile and run it with
"make test"). This version has no known bugs.
The data format used by the zlib library is described in the
files zlib-3.1.doc, deflate-1.1.doc and gzip-4.1.doc, available

All functions of the compression library are documented in the file
zlib.h. A usage example of the library is given in the file example.c
which also tests that the library is working correctly.

To compile all files and run the test program, just type: make test

for VMS, use Make_vms.com or descrip.mms.)
To install the zlib library (libz.a) in /usr/local/lib, type: make install
To install in a different directory, use for example:
make install prefix=$HOME
This will install in $HOME/lib instead of /usr/local/lib.
The changes made in version 0.94 are documented in the file ChangeLog.
The main changes since 0.93 are:
- support MSDOS small and medium model
- fix deflate with flush (could sometimes generate bad output)
- fix deflateReset (zlib header was incorrectly suppressed)
- added support for VMS
- allow a compression level in gzopen()
- gzflush now calls fflush
- For deflate with flush, flush even if no more input is provided.
- rename libgz.a as libz.a
The changes made in version 0.95 are documented in the file ChangeLog.
The main changes since 0.94 are:
- fix MSDOS small and medium model (now easier to adapt to any compiler)
- inlined send_bits
- fix the final (:-) bug for deflate with flush (output was correct but
not completely flushed in rare occasions).
For MSDOS, the small and medium models are supported only for Microsoft C.
(It should be easy to support them for Borland C also, but I don't have
a recent Borland compiler to test with.) The small model currently works
for Turbo/Borland C but only with reduced performance to avoid any far
allocation (tested with -DMAX_WBITS=11 -DDEF_WBITS=11 -DMAX_MEM_LEVEL=3).
