+  avail_out as zero but there is nothing to do
+- added memcmp for non STDC compilers

-The changes made in version 1.1.3 are documented in the file ChangeLog.
-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)
-  See http://www.muppetlabs.com/~breadbox/software/assembly.html
-- add support for Delphi 3 in contrib/delphi (Bob Dellaca)
-- add support for C++Builder 3 and Delphi 3 in contrib/delphi2 (Davide Moretti)
-- 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.

+
+The changes made in version 1.1.4 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.
