Cenqua has posted the first release candidate of FishEye 1.0, a $999 payware tool for viewing CVS activity. I've been using FishEye lately as part of my work with the Jaxen Project. As well as drawing graphs of activity, it lets you see who's committing what when to CVS, what individual committers have been up to, what's going on in different branches, what's happened to particular files, and so forth. It's not essential, and I doubt I'd pay for it if Cenqua hadn't given Codehaus a free copy. XOM doesn't use it, and I haven't missed it there. However, FishEye is a nice tool that's a definite improvement over standard CVS and ViewCVS.
Dan Creswell has released version 2.1.18 of the Blitz JavaSpaces Server Edition and version 1.0.6 of the pure Java edition. Bltiz is an open source (BSD license) implementation of JavaSpaces that is Jini 2.0 enabled and implements smart indexing, tuneable persistence, and active/passive lease cleanup. This release expands configurability and improves performance.
