### New and noteworthy

#### New rules

*   The new Java rule {% rule "java/codestyle/FinalParameterInAbstractMethod" %} detects parameters that are
    declared as final in interfaces or abstract methods. Declaring the parameters as final is useless
    because the implementation may choose to not respect it.

```xml
    <rule ref="category/java/codestyle.xml/FinalParameterInAbstractMethod" />
```

   The rule is part of the quickstart.xml ruleset.

#### Modified rules

*   The Apex rule {% rule "apex/documentation/ApexDoc" %} has a new property `reportProperty`.
    If set to `false` (default is `true` if unspecified) doesn't report missing ApexDoc comments on properties.
    It allows you to enforce ApexDoc comments for classes and methods without requiring them for properties.
