I’ve just updated our Discourse installation to the latest version, and this brings several new features.
The composer now supports an optional rich text mode, in case you prefer that over the previous Markdown mode. Markdown remains the default, but you can switch at any time using the toggle in the composer toolbar.
Message reactions now support several emojis to choose from in addition to the basic like / heart reaction.
There’s probably quite a few other things as well, but those are the highlights I’ve noticed so far.
