Hi, I'm happy to announce the release of Hibernate OGM 4.2.0.CR1! This version brings initial support for Cassandra, new built-in types for boolean mapping, support for MongoDB replica set, query improvements and a fix in the way we store element collections with nested embeddables. You will find all the details in the blog [1]. Cheers, Davide [1] http://in.relation.to/Bloggers/CassandraSupportQueryImprovementsMoreBuilt...
