### New and noteworthy

#### New rules

This release ships with 1 new Java rule.

*   {% rule java/errorprone/ReturnEmptyCollectionRatherThanNull %} suggests returning empty collections / arrays
    instead of null.

```xml
    <rule ref="category/java/errorprone.xml/ReturnEmptyCollectionRatherThanNull" />
```

   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.
