- Renaming a folder no longer duplicates its requests and subfolders
- Store authentication secrets of open tabs in the system keyring instead of plain text
- Saving an inactive tab from the tab bar saves that tab instead of the active one
- Remove a collection's variables file when all its variables are cleared
- Disconnect from MQTT brokers cleanly so the Last Will message is not published
- Fix gRPC message skeletons for recursive message types, cURL imports with -u credentials
and script test results when a script throws
- Data from before Resonance 3.3.1 is no longer converted; install 3.6.0 once first to
upgrade it
