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.
