Edit: If you downloaded it already, download again. I fixed a bug with the updater that made it think it was always out of date.
Here's another update to TabbyChat. This fixes issues with outbound chat not being sent and links not being clickable. It also adds an update checker. An update to MnmUtils is not required.
2.0.0-beta2a: Main | Dev
MnmUtil downloads are in the previous post.
As always, report bugs.
