Watchdog check has a new behavior:
In all releases until now, errors could be moved out of the limit over time (50 by default). This release prevents benign debug or info messages from hiding warnings and errors. Now, the only way to get Nagios green is to delete the triggering records from the watchdog database table explicitly. I hereby ask the community: is there a module that allows selectively deleting some types of watchdog entries while keeping most in the database? If you know the answer, please create an issue in the Nagios issue queue and I'll update this text here.
Improvements:
Added Drush command for querying Nagios. It allows transport via NRPE instead of Drupal's HTTP status page.
The most severe watchdog entries are now shown first. Chronological sorting is only applied among entries of equal severity.
