For those who are interested in the software we use to run TidBITS Talk, here are the release notes outlining new features in Discourse 2.5. It’s focused on people who run the site, so you may not see all the capabilities if I haven’t turned them on or if you don’t have the appropriate permissions, but a lot of the changes affect all users.
Thanks, Adam. Just out of curiosity, have you already updated? Or do you follow a fixed maintenance/update cycle?
