## New Supported Languages 

*   CPD supports now Swift (see [PR#33](https://github.com/adangel/pmd/pull/33)).

## Feature Request and Improvements 

*   A JSON-renderer for PMD which is compatible with CodeClimate. See [PR#83](https://github.com/pmd/pmd/pull/83).
*   [#1360](https://sourceforge.net/p/pmd/bugs/1360/): Provide backwards compatibility for PMD configuration file

## Modified Rules 

*   java-design/UseVargs: public static void main method is ignored now and so are methods, that are annotated with Override. See [PR#79](https://github.com/pmd/pmd/pull/79).

## Pull Requests 

*   [#27](https://github.com/adangel/pmd/pull/27): Added support for Raw String Literals (C++11).

*   [#33](https://github.com/adangel/pmd/pull/33): Added support for Swift to CPD.
*   [#79](https://github.com/pmd/pmd/pull/79): do not flag public static void main(String[]) as UseVarargs; ignore @Override for UseVarargs

## CLI Changes 

*   CPD: If a complete filename is specified, the language dependent filename filter is not applied. This allows to scan files, that are not using the standard file extension. If a directory is specified, the filename filter is still applied and only those files with the correct file extension of the language are scanned.
*   CPD: If no problems found, an empty report will be output instead of nothing. See also [#1481](https://sourceforge.net/p/pmd/bugs/1481/)
*   New command line parameter for PMD: <tt>-norulesetcompatibility</tt> - this disables the ruleset factory compatibility filter and fails, if e.g. an old rule name is used in the ruleset. See also [#1360](https://sourceforge.net/p/pmd/bugs/1360/). This option is also available for the ant task: <tt><noRuleSetCompatibility>true</noRuleSetCompatibility></tt>.
