Discourse 2.0.0.beta5 Release Notes

New features in 2.0.0.beta5

Shared Drafts

Shared drafts allow site staff to quickly and easily collaborate on a topic draft prior to making it public. To create a shared draft click the reply icon in the top left of the composer and select Shared Draft.


After the draft is created all staff can make edits prior to publishing the topic. Once published the timestamp(s) will be reset, and the edit history removed. For more details see the feature announcement at Shared Drafts: Allow staff to collaborate on posts before publishing.

Improved Staff Action Logging

Discourse aims to provide a simple audit path for staff actions via the staff action log (/admin/logs/staff_action_logs). This allows staff to review not only which staff member completed the action, but also when and the context of the action. Changes to site settings and themes also log the previous value making it easy to revert changes if needed.

In 2.0.0.beta5 we’ve added logging for “restore topic” and “staff edits”.

Easier Theme Development

@sam was very happy to release the Discourse Theme CLI (console app to help you build themes) to rubygems 2 weeks ago. This app makes theme development even easier by allowing developers to work on the theme in the editor of their choice! Working on the app Sam also squashed a few lingering bugs surrounding themes including some preview and caching issues.

Improved Group UX

We’ve made significant improvements to the /groups UX during 2.0.0.beta5, including:

  • Groups can now be filtered helping you find just the group you want.
  • Owners can quickly add or remove members from the group, and admins can easily designate owners.
  • Group members can interact with the message inbox right from the group page.
  • Group topic activity now uses the “latest” view providing all the details you’re used to from browsing Discourse like normal.

Remove category description in category-drop for staff or TL > 0

No, you’re not going crazy. Category descriptions have been removed from the category dropdown filter for staff and TL1+ users. This allows many more categories to fit without scrolling, as staff and non-new users should have a good idea what each category is for. Descriptions are still provided with hover tooltips, and continue to be listed in the composer category dropdown.


New Banner Themes

A frequent request here on Meta is for assistance customizing the look and feel of a site. To help admins get started @dax has created a number of “banner themes” that admins can import and customize on their site. Be sure to check out all the options and full details at Banner themes (and instructions for customizing them).
