Ignite Realtime Blog: Openfire 4.6.7 released (Log4j 2.17.1 only change)
Openfire 4.6.7 has been released with only a single change to bump the bundled log4j library to version 2.17.1. Whilst we do not believe Openfire to be vulnerable to the CVEs associated with the log4j 2.17.0 and 2.17.1 releases, we realize that many folks are running naive security scanners that are simply checking for bundled jar versions.

  3. 想要表示的值标记 1:10001010
有什么好处?

Paul Schaub: PGPainless 1.0.0 Released!
Close to the end of 2021 I’m excited to announce the release of PGPainless version 1.0.0! After a series of release candidates, it is finally time to party! The OpenPGP library successfully underwent a security audit in late November and I feel like it finally reached a state of sufficient maturity to be worthy of a major release with a “1” at the front.
