Summary
Adds a note to the Changelog entry for the 5.2.4.1 release, warning of a couple of breaking changes that occurred around session ids as a result of the security patch.
Other Information
While I think the origins of the change lie in
rack
and I am very grateful for the security patch having been released, having just deployed a buggy release after updating a rails 5.2 app (in part due to that app not testing the return type ofsession.id
) I hope this can help others avoid the same fate.Note that I have not been directly affected by the breaking change for ruby 2.2 users, but I've attempted to pinpoint the exact use case that will run into the problem.
