We use isDebugEnabled when it takes cost to create instances that are logged.

Ah, I thought that there would be some cost if a throwable was passed in.
Went through the code and verified at least logback terminates early 👍

As you know the error is safely ignored. How about setting the level to trace to log the cause only when users really want to delve into something?

Motivation: When the target release version changed from 1.21.0 to 1.20.3, some PRs were already merged into the master branch. So their milestone should be changed and the release notes also need to be updated. Modifications: - Add #4515, #4507, #4484 and #4492 to the release notes. Result: Update the missing issues and PRs.

Motivation:
We sometimes encounter situations where HTTP/2 header frames are lost due to an exception.
Although a RST frame is sent in this case, remotes are still able to send data for the offending stream, which ends up in error logs which armeria doesn't understand.
e.g.
Although normally it might be noisy to be alerted of such failures, it might be useful to view such logs when debugging.
