Additionally, the current bugfix release breaks use-cases without deprecation. Even Log4j 2.x didn't outright break use-cases, they just changed to more secure default behavior. Logback's change in particular isn't even a fix, it is just a percaution.

Johannes Wüller I agree that removing functionality so abruptly as was done in 1.2.8 is very unpleasant. I apologize for the inconvenience.
