Mind you, old versions of Expo really aren't something you would like to use if you're getting back to it like right now; Expo's 3-monthly (I think?) release cycle, and their 3 major versions support policy make it quite hard to deal with, for example if you rely on things like Expo Go. If you had an Expo project as recent as Expo 43 and are just maintaining it today, you won't even be able to test it out on Expo Go (on device that is; their old versions of simulator clients are here https://api.expo.dev/v2/versions/latest), support being dropped already.

Especially now is a bad time to claim that Expo makes transitioning painless - Expo is under major transition to their new EAS services (and old Expo updates are going to be dropped permanently in 2 months) and support for the new React Native Architecture is significantly changing their build process.

I would agree that before Expo's recent major changes (which I applaud), upgrades have generally been quite smooth.

Thankfully, the latest Expo versions seem to allow much more flexibility in the build process, making it much more viable for me to do my own Expo builds and stay mostly intact from Expo's support cycles.
