This is a minor fix required for some products. Please install the add-on if any version of a product you are using requires it.
The previous update missed some of the core classes used by some products. Please apply this version if you are getting a server error with our Guest Posting or Link Checker add-ons.
This is a minor update for upcoming versions of our add-ons. No need to upgrade your package unless you are using an add-on that requires this version.
