### New and noteworthy

#### CPD now supports XML as well

Thanks to [Fernando Cosso](https://github.com/xnYi9wRezm) CPD can now find duplicates in XML files as well.
This is useful to find duplicated sections in XML files.

#### New Rules

*   The new Java Rule {% rule "java/bestpractices/LiteralsFirstInComparisons" %} (`java-bestpractices`)
    find String literals, that are used in comparisons and are not positioned first. Using the String literal
    as the receiver of e.g. `equals` helps to avoid NullPointerExceptions.
    
    This rule is replacing the two old rules {% rule "java/bestpractices/PositionLiteralsFirstInComparisons" %}
    and {% rule "java/bestpractices/PositionLiteralsFirstInCaseInsensitiveComparisons" %} and extends the check
    for the methods `compareTo`, `compareToIgnoreCase` and `contentEquals` in addition to `equals` and
    `equalsIgnoreCase`.
    
    Note: This rule also replaces the two mentioned rules in Java's quickstart ruleset.
