Discourse 2.6.0.beta6 Release Notes

New features in 2.6.0.beta6

Disable local edits of remote themes

Add support for auto-updating themes on Discourse updates

Themes marked for auto update will be automatically updated when Discourse is updated.

Create revision when bulk moving topics

Previously when modifying a topic’s category or tags via bulk edits, no revision was logged. Revisions are now logged on bulk edits. For sites that wish to avoid revisions, disable the create revision on bulk topic moves site setting.

Link site setting titles directly to their change log

Ever wondered who changed a site setting, and when? Site setting changes have always been logged, but finding them amongst all the other logs can be tough. Now, to see the change log for a site setting, hover over the site setting title and click the history icon.

Improve errors when title is invalid

Discourse includes validation to help avoid ALL CAPS titles, titleswithreallylongwords, and titles with all the same letter. Previously, the error given was seems unclear, is it a complete sentence?, which doesn’t provide good feedback for the user to correct. Now, specific feedback is given:

"seems unclear, most of the words contain the same letters over and over?"
"seems unclear, one or more words is very long?"
"seems unclear, did you mean to enter it in ALL CAPS?"

Allow /u/by-external to work for all managed authenticators

Add Google Universal Analytics v4 as an option

Per Google, sites are encouraged to upgrade from Universal Analytics v3 analytics.js to v4 gtag.js for Google Analytics tracking. We’re giving admins the option to stay on the v3 API or migrate to v4. Admins can change the implementation they’re using via the ga_version site setting.

Create a linked topic on autoclosing mega topics

When topics exceed 10,000 posts, performance begins to degrade. As such, Discourse closes topics that reach the threshold automatically. Now, when such topics are closed, a new topic is created automatically to continue the discussion. For more details, see Linked topics (splitting and managing megatopics)

log_out_strict is default disabled

Previously, when a user logged out of Discourse, they would be logged out on all browsers and devices. As users can now view all devices from their preferences, and log out all devices from there, the log out button will now only log out the current browser/devices. Sites can revert to the previous default by re-enabling log out strict in site settings.

Category group moderator improvements

Category group moderators can now delete topics within the category.
