Jira has many open items that need to be completed for release 2.1. Some of the more major ones are:
Docbook
http://issues.apache.org/jira/browse/UIMA-3 Completing the transition of the documentation to docbook, and figuring out workarounds for all the parts of that process which are not quite working.
Rewrite of a few Eclipse modules
http://issues.apache.org/jira/browse/UIMA-2 We have a few modules in the Eclipse tooling that are written as derivative works of Eclipse source files. Because of this, the source for these cannot be distributed by Apache under the Apache 2.0 license. These modules need to be rewritten using more standard Eclipse APIs instead of being derivative works of Eclipse source.
Tooling to support the Apache namespace movement
http://issues.apache.org/jira/browse/UIMA-19 It would be nice to have instructions and tooling that supported users making the transition to Apache UIMA.
