Can't revert 0.26.1 back to 0.26
I upgraded from 0.26 to 0.26.1. I then saw issue 1243 (exception on deleting a task). I then tried to revert back to 0.26 but the application failed to start. The log shows this message:
Thu, 22. October 2015, 05:05 -> Thu Oct 22 05:05:47 CDT 2015
FATAL ApplicationStarter Starting application failed. Application startup failed. Data integrity check or repair failed. <- IllegalStateException: Data stored in /usr/share/tomcat/webapps/scrum-data/entities was created by a newer version of the application. You have probably downgraded. Since data formats changed, this is not possible. Application version is 36, data version is 37.

Upgrading data store versions in a bug fix release is not very nice. I would accept a change like that in a major, or even a minor, version update but certainly didn't expect it in a point release. Now I am stuck on 0.26.1 with a significant bug.
