CWIS version 3.1.1 has been released, and is now available for download on the Scout site.
This is primarily a bug fix release, addressing issues that have been discovered and resolved since 3.1.0, but it does introduce experimental support for SASS (SCSS), which can make CSS for custom interfaces much easier to write and maintain. For more specific information about what 3.1.1 includes, please see the CWIS Revision History option, available off of the Administration menu. CWIS 3.1.1 requires PHP 5.2.1 or newer and MySQL 5.0 or newer.
