[MatadorProBr]

Pre-Flight Checklist

• I am not asking a question => use the Discord if you are
• I have checked that someone else has not reported this using the search bar
• My feature request is not one of the commonly suggested features: iOS app (it's already being development)

Is your feature request related to a problem? Please describe.

No, when you launch BetterCrewLink for the first time after updating, could show a changelog inside the app showing what has changed in this new version and maybe use CHANGELOG.md for that

Describe the solution you'd like

When you launch BetterCrewLink for the first time after updating will show a CHANGELOG of what changed in the new version

Describe alternatives you've considered

Add a option in the BetterCrewLink settings that if you click, you will open the Changelog of the new version
