### New and noteworthy

#### New Rules

*   The new Java rule {% rule "java/bestpractices/ForLoopVariableCount" %} (`java-bestpractices`) checks for
    the number of control variables in a for-loop. Having a lot of control variables makes it harder to understand
    what the loop does. The maximum allowed number of variables is by default 1 and can be configured by a
    property.

*   The new Java rule {% rule "java/bestpractices/AvoidReassigningLoopVariables" %} (`java-bestpractices`) searches
    for loop variables that are reassigned. Changing the loop variables additionally to the loop itself can lead to
    hard-to-find bugs.

#### Modified Rules

*   The Java rule {% rule "java/codestyle/LocalVariableCouldBeFinal" %} (`java-codestyle`) has a new
    property `ignoreForEachDecl`, which is by default disabled. The new property allows for ignoring
    non-final loop variables in a for-each statement.
