Teiid 8.12 Beta1 has been released. The feature highlight since Alpha2 is TEIID-3595/TEIID-3594 which were logging enhancements for command and audit logging - more granularity of the levels and more security events.
There have also been several HBase/Phoenix fixes and a variety of other fixes. Expect another Beta release in about 2 weeks.
Thanks again for the community support and let us know if you find anything with the pre-release.
