After a local test run of WP-BlackCheck Version 2.2, I decided to say it’s safe for global usage.. The highlights of this version are:

• Update notifications
• Checking for Requirements
• Purging of old comments
• Some language improvements

Update: As I did hit a bug on 2.2.0 I had to release the bugfix release 2.2.1 and 2.2.2 to prevent you from having a disaster with your reportings.
