There has been a ton of work done over the past 3 months focused on bug fixing and bringing Teiid Designer up-to-speed with both JBoss Tools integration/compatibility as well as upgrading to Teiid 7.2 client/api.
We've also spent time fine-tuning the newer features introduced in 7.0 & 7.1.
So try it out... download Teiid Designer 7.2 Beta 1 now! (don't forget Teiid 7.2 )
