Is your feature request related to a problem? Please describe.
I'm always frustrated when I unnecessarily spend time on things that could be clearly stated. Migrating a microservice to Spring Boot 3 (with Spring Cloud to 2022 and some other dependencies). Having no migration guide (maybe I missed one?) for Spring Cloud OpenFeign 4.0, I just bumped the version(s) and... luckily I had some integration test to verify the timeout behavior. They stopped working and after "some time" I've bumped into https://github.com/spring-cloud/spring-cloud-openfeign/pull/679/ where the property prefix was changes from feign. to spring.cloud.openfeign. :-).
All the custom configuration (also on production) would have to be ignored.
Describe the solution you'd like While - in general - the new properties are covered in the documentation for 4.0, people doing migration might expect some kind of a migration guide to know what backward incompatible changes have been made. It could be in the GitHub release notes for 4.0 and/or as a separate section in the official documentation.
Additional context Maybe there are any other "important" changes in 4.0 to be aware of?

Right @szpak, thanks for pointing this out. It should have been added to the breaking changes list that we have created for this release (that's where various other important changes are listed as well). We must have overlooked it. Have added it now.

Thanks Olga. Yes, I was looking also at that page before :-). Nevertheless, maybe you could put a link to that generic document in the release notes for 4.0.0 in this repo?
