Hi,
I’m wondering if 3.0 is a drop-in upgrade or is there some things we should take care of when upgrading from 2.x to 3.x, especially if we’re not moving from Connect at the moment?
Please note, the question is about upgrading atlassian-connect-spring-boot, not the spring boot itself, which also released 3.x version very recently
@kazimir_io part of the scope of 3.0.0 was covered in Announcing atlassian-connect-spring-boot 3.0.0-beta-1 release and the linked changelog entry. Yes, there were some API-breaking changes.
The added feature in 3.0.0 is related to Migrating an app from Connect to Forge.
Also see the changelog entry Authenticate using OAuth2.0 when migrating Apps from Connect to Forge.
