### New and noteworthy
#### New Rules
* The new Java rule {% rule "java/codestyle/UseUnderscoresInNumericLiterals" %} (`java-codestyle`)
verifies that numeric literals over a given length (4 chars by default, but configurable) are using
underscores every 3 digits for readability. The rule only applies to Java 7+ codebases.
