I noticed that a new version of zlib was released last year. 1.2.0 came out in March through 1.2.1 in late November. There are a lot of API changes and new DLL support, but the new code seems to work fine with a Python build. That is, it compiles with minor changes to the build and the tests all pass. Even if we don't change our code at all, inflate is about 20% faster and crc32 is about 50% faster.

Sounds good. Note that we're not using the DLL.

Shall we upgrade the Windows build to use this new version? I have the changes made locally, but don't want to commit until people have had a chance to grab the new source. "Tim Peters" <tim.one at comcast.net> writes:

I have the changes made locally, but don't want to commit until people have had a chance to grab the new source. Which Windows build(s)? If you mean the 2.4 VC7 Windows build, sure. The VC6 build appears to be officially unsupported now, so unsure about that one. If there's another kind of "security fix" gimmick in 1.2.0 or 1.2.1, then a backport to 2.3 maint would also be appropriate.

I've skimmed through the changelog, and noticed no such security fix. So I suggest to change it for 2.4, but leave 2.3 alone.
