Its the Beta before version 3.1, and I'm still not sure about everything that's new in it, but the site is reporting that this version fixes all the bugs in the earlier version.
as for a provider implementation for ODP.Net - there seems to be one in the site's forum for Oracle.Net, but not for ODP (these are 2 different Oracle managed provider implementations available today). Surely,it shouldn't be that hard to create one, should it?
