+## Major impact changes
+- TODO move away from SSP database as store; move to custom store interface
+
+## Medium impact changes
+- TODO move to SSP (symfony) routing
+  - TODO handle CORS
+
+## Low impact changes
+
+Below are some internal changes that should not have impact for the OIDC OP implementors. However, if you are using
+this module as a library or extending from it, you will probably encounter breaking changes, since a lot of code
+has been refactored:
+
+- TODO upgrade to v5 of lcobucci/jwt https://github.com/lcobucci/jwt
+- TODO move checkers to templates (generics) for proper static type handling
+- TODO move to SSP (symfony) container
+- TODO remove dependency on laminas/laminas-diactoros
+- TODO remove dependency on laminas/laminas-httphandlerrunner
+- TODO create a bridge towards SSP utility classes, so they can be easily mocked
