Hi Derick,
Thanks for that new version.
For now I just tested upgrading from dotLRN 2.4.1 and had the following error message in the log:
Error: lang::message::register - refusing to register message for non-en_US locale es_ES. The message key imsld.IMS-LD_Level must be registered in en_US first
Will test further during the next two weeks.
Also FYI, dotlrn hasn't been branched yet so this version is the one that will go into the next release (2.5.0).
