**Version 2.8.1**
* This release contains a fix for a security advisory related to the improper handling of shell commands
* Uses of shell_exec() and exec() were not escaping filenames and configuration settings in most cases
* A properly crafted filename or configuration option would allow for arbitrary code execution when using some features
* All users are encouraged to upgrade to this version, especially if you are checking 3rd-party code
* e.g., you run PHPCS over libraries that you did not write
* e.g., you provide a web service that runs PHPCS over user-uploaded files or 3rd-party repositories
* e.g., you allow external tool paths to be set by user-defined values
* If you are unable to upgrade but you check 3rd-party code, ensure you are not using the following features:
* The diff report
* The notify-send report
* The Generic.PHP.Syntax sniff
* The Generic.Debug.CSSLint sniff
* The Generic.Debug.ClosureLinter sniff
* The Generic.Debug.JSHint sniff
* The Squiz.Debug.JSLint sniff
* The Squiz.Debug.JavaScriptLint sniff
* The Zend.Debug.CodeAnalyzer sniff
* Thanks to Klaus Purer for the report

* PEAR.Functions.FunctionDeclaration now reports an error for blank lines found inside a function declaration
* PEAR.Functions.FunctionDeclaration no longer reports indent errors for blank lines in a function declaration

* It would previously report that only one argument is allowed per line
