2015-06-22 16:59 AEST by Arthur Barrett - For Windows (only?) we include ZLIB in CVSNT because it's not available on windows.

We should upgrade the current version to the latest (1.2.8?) for bug fixes, e.g.:
April 28, 2013: Version 1.2.8 fixes a very rare bug in decompression.

I also see mention of alternatives: CloudFare and zlib-ng implementations

2022-05-02 21:17 AEST by Arthur Barrett - zlib 1.2.12.1 is the latest optimised version...

2022-05-04 14:01 AEST by Arthur Barrett - tested against our main cvsnt server using cvs -z0 and cvs -z9 and the traces 
and protocol traces are what you would expect.  Note: I discovered bug 7610 
this way.

2022-05-04 14:02 AEST by Arthur Barrett - not fixed - comment added to wrong bug

2024-08-30 12:46 AEST by Arthur Barrett - note: TortoiseCVS has its own copy of zlib that probably also needs updating
