A quick bugfix update to 3.6.0, which was a great release but broke copy/paste. No more! We have promptly fixed this in 3.6.1.
If you have multiple Mudlet versions or the wrong one is launching, uninstall them all and install just 3.6.1. This is due to us switching to a better installer which you’ll notice is much, much quicker. All of your profiles will stay!
