Hi, 4.2.ALPHA3 was mistakenly released from trunk (i.e. it is rather a trunk snapshot release). Because we port all our changes from 4.2 to trunk on each commit, you most likely won't be affected by this, unless: - if data are store with 4.2.0.ALPAH3, you might not read it properly with another 4.2.x version - you are using Apache avro based marshaller which is only developed on trunk and won't work on next alpha relese. Sorry for the trouble caused! Mircea
