This update is primarily to fix various bugs and to give everyone a much improved performance in recent search with big or lots of logs. A major algorithm change should make ausearch/report faster searching anything recent. This update adds anomaly, response, and crypto reports to aureport. The af_unix plugin got a lot of attention and should be working better than ever.
But there is one big change that distribution packagers should be aware of. The audit.pid file, the directory where everything is stored has potentially been changed. The location is now based off of --runstatedir passed to configure. On modern linux systems, this is /run. Legacy systems would have this as /var/run. If the distribution uses MAC, this change needs to be updated in the MAC security policy. Be sure to check that you set this appropriately.
