The changes made in version 1.1.1 are documented in the file ChangeLog.
The main changes since 1.1.0 are:
- fix macros _tr_tally_* in deflate.h for debug mode (Glenn Randers-Pehrson)
- remove block truncation heuristic which had very marginal effect for zlib
(smaller lit_bufsize than in gzip 1.2.4) and degraded a little the
compression ratio on some files. This also allows inlining _tr_tally for
matches in deflate_slow.
The changes made in version 1.1.2 are documented in the file ChangeLog.

- added contrib/minzip, mini zip and unzip based on zlib (Gilles Vollant)

- zlib doesn't work with gcc 2.6.3 on a DEC 3000/300LX under OSF/1 2.1
it works when compiled with cc.
- on Digital Unix 4.0D (formely OSF/1) on AlphaServer, the cc option -std1
is necessary to get gzprintf working correctly. This is done by configure.
- zlib doesn't work on HP-UX 9.05 with some versions of /bin/cc. It works
with other compilers. Use "make test" to check your compiler.

Acknowledgments:
The deflate format used by zlib was defined by Phil Katz. The deflate
and zlib specifications were written by Peter Deutsch. Thanks to all the
and zlib specifications were written by L. Peter Deutsch. Thanks to all the
people who reported problems and suggested various improvements in zlib;
they are too numerous to cite here.

UnZip 0.15 additionnal library
This unzip package allow extract file from .ZIP file, compatible with
PKZip 2.04g, WinZip, InfoZip tools and compatible.
Multi volume ZipFile (span) are not supported, and old compression used by old
PKZip 1.x are not supported.
See probdesc.zip from PKWare for specification of .ZIP format.
What is Unzip
The Zlib library support the deflate compression and the creation of gzip (.gz)
file. Zlib is free and small.
The .Zip format, which can contain several compressed files (.gz can containt
only one file) is a very popular format. This is why I've written a package for reading file compressed in Zipfile.
Using Unzip package
You need source of Zlib (get zlib111.zip and read zlib.h).
Get unzlb015.zip and read unzip.h (whith documentation of unzip functions)
The Unzip package is only two file : unzip.h and unzip.c. But it use the Zlib
files.
unztst.c is a simple sample program, which list file in a zipfile and display
README.TXT or FILE_ID.DIZ (if these files are found).
miniunz.c is a mini unzip program.
I'm also currenlyt writing a zipping portion (zip.h, zip.c and test with minizip.c)
Please email me for feedback.
I hope my source is compatible with Unix system, but I need your help for be sure
