An update to ibm_db Rails adapter is available on RubyForge.com

If you are getting your DB2 (and IDS) Ruby driver and Rails adapter as a gem from RubyForge, then you would be happy to know that a new update is available. This updates brings ibm_db Rails adapter to version 0.7.0. There are no updates to the Ruby driver—only the adapter is updated.
Alex Pitigoi posted a short description of the fixes that went in to this version of the adapter. Based on our experience in Project Aurora, I recommend that anyone working with XML upgrade to this level right away.
