The scheduled date for the IMP 2.1 release is coming up in about a month. If there is anything that it is important happen before then, please make there is an issue in the tracker that is tagged with the 2.1 release milestone. Also, please check the tracker and see if there are issues assigned to you that are tagged for the release and deal with them (in the worst case by just marking them as for the 2.2 release).

In addition, if you have many any particularly interesting changes to code, add a brief description to the ChangeLog.md.

Some time after the 2.1 release, I'll start removing things marked as deprecated, so please clean up such usages in your code.
