We have made a couple dozen bug fixes and improvements since the last release of Roller (5.1.2 on March 31, 2017).
Here's a list of things we've resolved since then: https://issues.apache.org/jira/issues/?jql=project%20%3D%20ROL%20AND%20resolved%20%3E%3D%202015-03-31%20AND%20resolved%20%3C%3D%202017-06-17 I'm planning to put together a release candidate in the next week so we can get these changes out. Please speak up if you have anything you'd like to get into this release. Thanks, Dave
