ChangeLog file for zlib
Changes in 1.1.4 (11 March 2002)
- 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).
Changes in 1.1.3 (9 July 1998)
- fix "an inflate input buffer bug that shows up on rare but persistent
occasions" (Mark)

The main changes since 1.1.2 are:
- fix "an inflate input buffer bug that shows up on rare but persistent
occasions" (Mark)
- fix gzread and gztell for concatenated .gz files (Didier Le Botlan)
- fix gzseek(..., SEEK_SET) in write mode
- fix crc check after a gzeek (Frank Faubert)
- fix miniunzip when the last entry in a zip file is itself a zip file
(J Lillge)
- add contrib/asm586 and contrib/asm686 (Brian Raiter)

- do not exit prematurely in untgz if 0 at start of block (Magnus Holmgren)
- use macro EXTERN instead of extern to support DLL for BeOS (Sander Stoks)
- added a FAQ file
plus many changes for portability.
