In #2691 <https://github.com/apache/logging-log4j2/pull/2691>, I teamed up with Alan to rewrite the stack trace rendering in Pattern Layout. Since this will have a major impact on users, and even though I implemented 1579 new tests[1], I appreciate your reviews too.
[1] Yes, I replaced ~30 tests with 1579 new ones. You can check it yourself too: `./mvnw test -pl :log4j-core-test -Dtest="*ThrowablePatternConverterTest"`
