Hi there,
I know you can't fix the announcements already sent out, but fpr future
announcements and in case the release announcement text is also part of
the log4j web pages one should maybe rephrase:
"Log4j 2 is an upgrade to Log4j that provides significant
improvements ... such as support for... property substitution using
Lookups..."
The mentioning of lookups here might need clarification. When 2.17.0
gets out, people might get afraid, that the lookup problem might have
been reintroduced.
For the sake of completeness: the 2.16.0 announcement also contained:
"Prior to version 2.15.0, Log4j would automatically resolve Lookups
contained in the message or its parameters in the Pattern Layout. This
behavior is no longer the default and must be enabled by specifying
%msg{lookup}."
AFAIK that was true for 2.15.0, but no longer for 2.16.0. The
announcement for 2.12.2 instead contained the more correct
"Removed Message Lookups in PatternLayout. "%m{lookup}",
"%m{nolookup}", and variants will still be accepted as conversion
patterns, but have no effect."
Thanks and regards,
Rainer
