+2003-09-10 rk
+Removed "File Info.vi". it uses a CIN Manager function which
+starts to behave rather badly in newer (>=7.0) non-Windows LabVIEW version.
+
+2005-01-12 rk
+Incorporated newest zlib version 1.22 and 1.0.1 of Jean-loup Gailly's
+minizip library. Added and adapted VIs to support addition of files to
+existing archives, delete files from an archive, and add and retrieve
+password protected files.
+Fixed a bug in the "File Info.vi" in the file package and reactivated
+it in the lvzip library.
+
+2005-04-04 rk
+Many minor changes to the shared library to clean it up and make it
+compile on Linux, too
+
+2005-04-12 rk
+Changed several connector panes to 12 pane connector to generalize and
+allow for consistent password parameter support up to the top most
+(easy level) VIs.
+
+2005-04-14 rk
+Added functionality to prepend the file name to the error message if an
+input file couldn't be found.
+
+2005-12-31 rk
+Found that the last build on sf did not include the modified VIs. Cleaned
+up a bit.
+
+2006-01-02 jk
+Added the Xcode project files and source code.
+
+2006-01-04 rk
+Combined the Macintosh C source and Xcode project file into the standard
+C source directory.
+
+2006-01-07 rk
+Updated zlib sources to version 1.2.3 as they have some important security fixes.
+
+2006-03-01 rk
+Added support for transparent Macintosh resource file handling through MacBinary encoding.
+
+2006-09-23 rk
+Fixed error in LabVIEW 8 when extracting read-only files.
+
+2007-09-10 rk
+Added support for adding and extracting memory streams to and from a ZIP file.
+
+2007-09-16 rk
+Added support for ZIP streams itself instead of disk based ZIP files.
+
+2007-12-8 rk
+Minor modifications to try to get it to compile in LabWindows/CVI
+
+2007-12-10 rk
+created vxWorks .out shared libraries for LabVIEW RT 8.2 and 8.5.
+
+2008-03-31 rk
+changed zipOpen2() to properly open an empty archive that contains no files at all
+
+2008-04-28 rk
+changed ZLIB Store File.vi to also work for LabVIEW files that are located in LLBs
+by creating a temporary copy to add to the archive.
+
+2008-10-25 rk
+Added missing VI documentation to various VIs.
+changed ZLIB Delete Files From Archive.vi to use a correct temporary filename for
+the intermediate archive file.
+by creating a temporary copy to add to the archive.
+
+2008-12-23 rk
+Prepended all public symbols with lvzip_ to avoid name conflicts with the LabVIEW
+VxWorks kernel on cRIO targets.
+
+2008-12-24 jk
+Removed Mac OS 9 shared library and changed to zip format for packaged Mac OS X framework.  Still need to update install script VI to handle unzipping via command-line during install.
+
+2008-12-27 jk
+Changed package URL to http://wiki.openg.org/oglib_lvzip

+                ChangeLog file for zlib
+
+Changes in 1.2.3 (18 July 2005)
+- Apply security vulnerability fixes to contrib/infback9 as well
+- Clean up some text files (carriage returns, trailing space)
+- Update testzlib, vstudio, masmx64, and masmx86 in contrib [Vollant]
+
+Changes in 1.2.2.4 (11 July 2005)
+- Add inflatePrime() function for starting inflation at bit boundary
+- Avoid some Visual C warnings in deflate.c
+- Avoid more silly Visual C warnings in inflate.c and inftrees.c for 64-bit
+  compile
+- Fix some spelling errors in comments [Betts]
+- Correct inflateInit2() error return documentation in zlib.h
+- Added zran.c example of compressed data random access to examples
+  directory, shows use of inflatePrime()
+- Fix cast for assignments to strm->state in inflate.c and infback.c
+- Fix zlibCompileFlags() in zutil.c to use 1L for long shifts [Oberhumer]
+- Move declarations of gf2 functions to right place in crc32.c [Oberhumer]
+- Add cast in trees.c t avoid a warning [Oberhumer]
+- Avoid some warnings in fitblk.c, gun.c, gzjoin.c in examples [Oberhumer]
+- Update make_vms.com [Zinser]
+- Initialize state->write in inflateReset() since copied in inflate_fast()
+- Be more strict on incomplete code sets in inflate_table() and increase
+  ENOUGH and MAXD -- this repairs a possible security vulnerability for
+  invalid inflate input.  Thanks to Tavis Ormandy and Markus Oberhumer for
+  discovering the vulnerability and providing test cases.
+- Add ia64 support to configure for HP-UX [Smith]

+- Fix crc check bug in gzread() after gzungetc() [Heiner]
+- Add the deflateTune() function to adjust internal compression parameters
+- Add a fast gzip decompressor, gun.c, to examples (use of inflateBack)
+- Remove an incorrect assertion in examples/zpipe.c
+- Add C++ wrapper in infback9.h [Donais]
+- Fix bug in inflateCopy() when decoding fixed codes
+- Note in zlib.h how much deflateSetDictionary() actually uses
+- Remove USE_DICT_HEAD in deflate.c (would mess up inflate if used)

+  avail_out as zero but there is nothing to do

+- fixed very unlikely race condition in ct_static_init
+- free in reverse order of allocation to help memory manager
+- use zlib-1.0/* instead of zlib/* inside the tar.gz
+- make zlib warning-free with "gcc -O3 -Wall -Wwrite-strings -Wpointer-arith
+  -Wconversion -Wstrict-prototypes -Wmissing-prototypes"

+- guard against multiple inclusion of *.h (for precompiled header on Mac)
+- Watcom C pretends to be Microsoft C small model even in 32 bit mode.
+- don't use unsized arrays to avoid silly warnings by Visual C++:
+     warning C4746: 'inflate_mask' : unsized array treated as  '__far'

+- faster crc32()
+
+Changes in 0.8 (29 April 95)
