This is primarily a maintenance release. It also provides a new tool that permits the recovery of disk queues, when the queue information file (.qi) has been lost. Thanks to Kaiwang Chen for contributing this tool.
There was an important flaw in 5.8.8 that caused disk queue content to be lost after a shutdown and restart of rsyslogd. So if you run this version, an upgrade to 5.8.9 is highly suggested.
As always, feedback is appreciated.
