Drizzle source tarball based on build 1088 has been released. The change log can be viewed here. While continuing to do a lot of great code clean up, this release also features work by Padraig who has got a great start working on extracting I_S out into plugins.
We also now support protobuf 2.1 except when using gcc 4.4 or if you are running on Solaris. Monty is working on getting a patch into protobuf 2.1.1 for the gcc 4.4 issue. He is also working closely with the SunStudio engineers to get that issue resolved as well.
