This is a vote to release Log4j 2.7, the next version of the Log4j 2 project.
Please download, test, and cast your votes on the log4j developers list.

The vote will remain open for 72 hours (or more if required). All votes are
welcome and we encourage everyone to test the release, but only Logging PMC
votes are “officially” counted. As always, at
least 3 +1 votes and more positive than negative votes are required.
