This is a maintenance update to address issues reported in the V5.2.1 release earlier this week.
One of the key additions is additional backwards compatibility for modules and custom pages written for earlier versions. This will mean that custom pages should require *NO* changes to continue functioning exactly as before.
Another point of note is that with the V5.2.1 update, the ResellerClub and all other LogicBoxes based modules were updated to use the new API Key method of integration which is safer and more secure, and so if you are a user of any LogicBoxes based domain registrar module in WHMCS you will need to enter an API Key in the Setup > Domain Registrars page before you can continue using it.
