I've just upgraded from 3.1 to 3.2.1, no problem there. When running 3.2.1 I noticed I couldn't connect to my printer (via Octoprint), the plugin wasn't installed. Pretty sure it was installed along with 3.1 but anyhow went to install it via the browse plugins UI, clicked on install, then got an error saying something along the lines of 'incorrect plugin file'. Octoprint connection wasnt available even though the plugin browser said it was installed. So decided to re-open cura just in case
