Apologies, but there was a non-obvious-but-show-stopper bug in the Beta 2 from this morning. The offending code has been removed, and OpenMRS 1.6 Beta 3 is now ready for testing. You can get it here.
Assuming no further major bugs, we should have the release candidate out in a week. We’re looking for one implementation (in addition to AMPATH, who has generously offered) to test out the release candidate in production, so we can be totally sure it’s stable. Let me know if you’re interested in that being you.
