ChangeLog file for zlib
Changes in 1.2.3 (18 July 2005)
- Apply security vulnerability fixes to contrib/infback9 as well

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()

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.

avoid implicit memcpy calls (portability for no-library compilation)
- Increase sprintf() buffer size in gzdopen() to allow for large numbers
- Add INFLATE_STRICT to check distances against zlib header
- Improve WinCE errno handling and comments [Chang]

Frequently Asked Question:
Q: Each time I use the compress function I get the -5 error (not enough
room in the output buffer).
A: Make sure that the length of the compressed buffer is passed by
reference ("as any"), not by value ("as long"). Also check that
before the call of compress this length is equal to the total size of
the compressed buffer and not zero.

looks correct):

gzopen
gzwrite
gzread
gzclose

says conforms to the VB guidelines, and that solves the problem of not
knowing the uncompressed size by storing it at the end of the file:

'bracket meaning: <parameter> [optional] {Range of possible values}
