I have prepared a release candidate #1 for a new release Roller v.5.2.1. The purpose of this release is to upgrade to Struts 2.5.17 which includes some security fixes. That is the only change in this release.
You can find the release files here: https://dist.apache.org/repos/dist/dev/roller/roller-5.2/v5.2.1-rc-1/ I've done some smoke-testing and will upgrade my site over the next day or two. Please take a look, try it out if you have time and I will call a vote probably tomorrow. Thanks, Dave
