Some history is removed

The new plugin "Database Cleaner" is packaged within Sonar. It aims to delete some rows in database to save some space and to improve overall performances. By default :

• it deletes all data older than 5 years
• it keeps a single monthly analysis by project over 1 year
• it keeps a single weekly analysis by project over 1 month
• analysis with an event are kept

These settings can be changed in the page Configuration > Settings > Database Cleaner.

The property "sonar.reuseExistingRulesConfiguration" is removed

This property has been used in the plugins Checkstyle and PMD. It has been deprecated in version 2.3 and is now deleted, as it is highly unstable and can not provide meaningful results.

Previous versions of the Views plugin are not compatible anymore. This plugin must be upgraded to version 1.5 :
