This release includes additional sanity checks to prevent bad data returned from the API from breaking the forums.
If any of the data returned by the API is not in the exact format we expect, the entire download is discarded and no changes applied to the forum. An error message will be logged prompting further investigation.
After upgrading to 4.0.1, you should manually force a fetch of new API data by executing the following command from your forum root:
php cmd.php known-bots:fetch -f
