I just recently completed the search functionality for BBWeblog v2, and have almost completed all the migration from JDBC based DAO to using Hibernate 3.0.
There is still a lot of code cleanup to do (the JDBC migration to Hibernate 3.0 reduced the code in the DAO by about two thirds!), but the current code is currently running on my site for my weblog and online tech notes (you’re looking at it right now!), and so it seems stable enough to run in production. I’ll continue the cleanup and then release the final v2 version when its cleaned up.
