I just tried to do the update process for Current to 1.0.3 via the plugin in Bitwig however it doesn’t work correctly.
While the update downloads and launches fine, at the point it tells you to “quit the DAW” if you do so then the install process is also killed and the only way to perform the update is to grab it from the site.
OS : Windows 10 x64
DAW : Bitwig 5.0.9
Current is the VST3 versions
(I’ve managed to update ok via just downloading the new installer, so this is mostly an FYI thing for future updates)
