Hi Arek,
It seems that the debug server connection discussed in this thread will be fixed.
Other thing discussed there is the “feature”? of MBed Studio to automatically update itself when a new version is available without asking permission to the user. Will the next version comming out 1.3.1 have the option to turn it off and only notify the user that a new version is available?. That will be consistent with the way new libraries on GitHub are notified, but not automatically updated in the project.
