Will the Cassandra database format for the current Cassandra source trunk be compatible with the 0.5 Cassandra release?
Yes. Only the commitlog format changes between 0.4 and 0.5, and that isn't a problem since you can just nodeprobe flush to get around it.
If there are database version differences, is there a migration path to convert older data formats to the new versions?
In the future if the format changes, there will be a migration path.
Is there an estimated release date for the 0.5 release?
Beta should happen fairly soon -- it's up for a vote in the IPMC right now.
