Release date: Jan 25th 2012
We recommend all users of 1.6.x upgrade to this version. The 1.6.5 database is compatible with v1.6.0/1.6.1/1.6.2/1.6.3/1.6.4, so rolling back your installation in the case of errors is trivial.
OpenMRS 1.6.5 represents build OpenMRS 184.108.40.20660
These modules are bundled with the 1.6.5 openmrs.war. They will be started automatically and can be removed if they are not wanted.
