The page "Hotspots" is implemented as a dashboard
It brings much more flexibility on the way to configure the hotspots widgets. The drawback is that the migration does not allow to "push" this page to users who have already customized their own dashboards. The Hotspots page is removed from sidebar for these users. They have to manually follow the shared dashboard named "Hotspots". See SONAR-3063.
The property "sonar.jdbc.driverClassName" is guessed
This property can be removed when using the default provided JDBC drivers. Note that the default value for Oracle is
oracle.jdbc.OracleDriver. See SONAR-3045.
Typo in the property "sonar.cobertura.maxmen"
This property has been renamed
sonar.cobertura.maxmem. The old wrong value is still supported for a few releases. See SONAR-2897.
The properties "sonar.hibernate.default_schema" and "sonar.jdbc.postgreSearchPath" are deprecated
They are replaced by the generic property
sonar.jdbc.schema. Note that they are still supported for a few releases. See SONAR-2975.
Java: metric "commented out lines of code" removed
Metric "comments" now includes all comments and new rule was added to detect commented out lines of code, which provides more precise results than previous way of metric computation. See SONAR-3093 and SONAR-2018.
