The changes made in version 1.0.7 are documented in the file ChangeLog.
The main changes since 1.0.6 are:
- Fix inflate to terminate gracefully when fed corrupted or invalid data
- Use const for rommable constants in inflate
- fix gzseek which was broken in write mode
- return error for gzseek to negative absolute position
- fix configure for Linux (Chun-Chung Chen)
- increase stack space for MSC (Tim Wegner)
- get_crc_table and inflateSyncPoint are EXPORTed (Gilles Vollant)
- define EXPORTVA for gzprintf (Gilles Vollant)
- added mini man page zlib.3 (Rick Rodgers) [volunteers to write full
man pages from zlib.h most welcome. write to jloup@gzip.org]
- for contrib/untgz, fix makedir() and improve Makefile

Notes for some targets:
- For Turbo C the small model is supported only with reduced performance to
avoid any far allocation; it was tested with -DMAX_WBITS=11 -DMAX_MEM_LEVEL=3
- To build a Windows DLL version, include in a DLL project zlib.def, zlib.rc
and all .c files except example.c and minigzip.c; compile with -DZLIB_DLL
The zlib DLL support was initially done by Alessandro Iacopetti and is
now maintained by Gilles Vollant <info@winimage.com>. Check the zlib DLL
home page at http://www.winimage.com/zLibDll
- For 64-bit Iris, deflate.c must be compiled without any optimization.
From Visual Basic, you can call the DLL functions which do not take
a structure as argument: compress, uncompress and all gz* functions.
See contrib/visual-basic.txt for more information.
I don't know how to handle structures in Visual Basic, sorry.
