Doug Smith introduced BlogSecurity to his latest WP plugin: WordPress Upgrade Preflight Check. This plugin aims to give you a heads of any compatibility problems before going through the upgrade process.

How It Works

This plugin works by scanning for the appearance of text within plugins and themes that may indicate compatibility problems.

It currently looks for the following:

• Use of the old category tables that are now gone.
• Use of wp-admin/upgrade-functions.php, which has been moved and renamed.
• Use of the get_the_title function, which works a little differently.
• Use of deprecated permalink functions, which still work for now but should be replaced.

Although this is a great idea, the techniques used to determine the compatibility concerns are by know means conclusive. I don’t think the author ever intended this tool to substitute backups.

More information about the plugin can be found on Doug’s blog. Great stuff Doug!
