@grgrzybek will there be any timeline on releasing with new dependency version.?.

[grgrzybek]

I just got back from PTO, so I can release somewhere next week, ok?

This may be tricky, as we have a version of DatePatternConverter with weak maps:

• Rewrite date & time formatting apache/logging-log4j2#3121

But now I can see ThreadLocals are no longer used, so we can remove the shaded version.

The default logging pattern changed a lot.... I have to adjust tests:

This changed default layout from PatternLayout to DefaultLayout:

• Create DefaultLayout independent of PatternLayout apache/logging-log4j2#3118
