The changes made in version 1.1.4 are documented in the file ChangeLog. The changes made in version 1.2.1 are documented in the file ChangeLog.
The only changes made since 1.1.3 are bug corrections:
- ZFREE was repeated on same allocation on some error conditions.
This creates a security problem described in
http://www.zlib.org/advisory-2002-03-11.txt
- Returned incorrect error (Z_MEM_ERROR) on some invalid data
- Avoid accesses before window for invalid distances with inflate window
less than 32K.
- force windowBits > 8 to avoid a bug in the encoder for a window size
of 256 bytes. (A complete fix will be available in 1.1.5).
The beta version 1.1.5beta includes many more changes. A new official
version 1.1.5 will be released as soon as extensive testing has been
completed on it.

This is a patched version of zlib modified to use
Pentium-optimized assembly code in the deflation algorithm. The files
changed/added by this patch are:
README.586
match.S
The effectiveness of these modifications is a bit marginal, as the the
program's bottleneck seems to be mostly L1-cache contention, for which
there is no real way to work around without rewriting the basic
algorithm. The speedup on average is around 5-10% (which is generally
less than the amount of variance between subsequent executions).
However, when used at level 9 compression, the cache contention can
drop enough for the assembly version to achieve 10-20% speedup (and
sometimes more, depending on the amount of overall redundancy in the
files). Even here, though, cache contention can still be the limiting
factor, depending on the nature of the program using the zlib library.
This may also mean that better improvements will be seen on a Pentium
with MMX, which suffers much less from L1-cache contention, but I have
not yet verified this.
Note that this code has been tailored for the Pentium in particular,
and will not perform well on the Pentium Pro (due to the use of a
partial register in the inner loop).
If you are using an assembler other than GNU as, you will have to
translate match.S to use your assembler's syntax. (Have fun.)

This is a patched version of zlib, modified to use
Pentium-Pro-optimized assembly code in the deflation algorithm. The
files changed/added by this patch are:
README.686
match.S
The speedup that this patch provides varies, depending on whether the
compiler used to build the original version of zlib falls afoul of the
PPro's speed traps. My own tests show a speedup of around 10-20% at
the default compression level, and 20-30% using -9, against a version
compiled using gcc 2.7.2.3. Your mileage may vary.
Note that this code has been tailored for the PPro/PII in particular,
and will not perform particuarly well on a Pentium.
If you are using an assembler other than GNU as, you will have to
translate match.S to use your assembler's syntax. (Have fun.)

These are files used to compile zlib under Borland C++ Builder 3.
zlib.bpg is the main project group that can be loaded in the BCB IDE and
loads all other *.bpr projects
zlib.bpr is a project used to create a static zlib.lib library with C calling
convention for functions.
zlib32.bpr creates a zlib32.dll dynamic link library with Windows standard
calling convention.
d_zlib.bpr creates a set of .obj files with register calling convention.
These files are used by zlib.pas to create a Delphi unit containing zlib.
The d_zlib.lib file generated isn't useful and can be deleted.
zlib.cpp, zlib32.cpp and d_zlib.cpp are used by the above projects.
