This release ships with 1 new Java rule.

The rule is part of the quickstart.xml ruleset.

Deprecated rules

The rule {% rule java/errorprone.xml/ReturnEmptyArrayRatherThanNull %} is deprecated and removed from the quickstart ruleset, as the new rule {% rule java/errorprone.xml/ReturnEmptyCollectionRatherThanNull %} supersedes it.
