Hi Shane, Does RelStorage 1.4 work with ZODB 3.10? (In particular, the Undo changes and the tightened storage API..) I see the mention of 3.10.0b7, but just wanted to check that means you're okay with 3.10 final ;-) cheers, Chris -- Simplistix - Content Management, Batch Processing & Python Consulting - http://www.simplistix.co.uk
