Changes in 0.91 (2 May 95)
- Default MEM_LEVEL is 8 (not 9 for Unix) as documented in zlib.h
- Document the memory requirements in zconf.h
- added "make install"
- fix sync search logic in inflateSync
- deflate(Z_FULL_FLUSH) now works even if output buffer too short
- after inflateSync, don't scare people with just "lo world"
- added support for DJGPP

The changes made in version 0.9 are documented in the file ChangeLog. To compile all files and run the test program, just type: make test
The main changes since 0.8 are: (For MSDOS, use one of the special makefiles such as Makefile.msc.)
- don't assume that zalloc clears the allocated memory To install the zlib library (libgz.a) in /usr/local/lib, type: make install
- let again gzread copy uncompressed data unchanged (was working in 0.71) To install in a different directory, use for example: make install prefix=$HOME
- deflate(Z_FULL_FLUSH), inflateReset and inflateSync are now fully implemented This will install in $HOME/lib instead of /usr/local/lib.
The changes made in version 0.91 are documented in the file ChangeLog.
The main changes since 0.9 are:
- Default MEM_LEVEL is 8 (not 9 for Unix) as documented in zlib.h
- Document the memory requirements in zconf.h
- added "make install"
- added support for DJGPP
On MSDOS, this version works in both large and small model. However On MSDOS, this version works in both large and small model. However

allocation of big objects. medium model with far allocation of big objects.
