Left 4 Dead 2 - Update

February 21, 2017 - Valve

An update has been released for Left 4 Dead 2. - Configuration files are no longer loaded from addon vpks. These configuration values were sometimes used for malicious purposes, and all changes remained in the user's local settings even after the addon was disabled or removed. When necessary, addon authors should inform users of any required configuration changes in the description on the workshop page.
