Paypal IPN process changes required for WPMU Dev Plugins?

This is not so much a plea for support as it is an alert about the notice I received below from PayPal.

Having experienced issues with IPN notifications working as expected for our integration of the Pro Sites and Fundraising plugins, I just wanted to provide this information and inquire if any updates will be required to the plugin code, or if any changes will be expected to our IPN Notification URLs or other plugin settings.

I'm certain the developers are aware of any changes PayPal is requiring, but just wanted to bring this up just in case.

Thanks in advance for any feedback.

FYI Only...

RE: Instant Payment Notification (IPN) process Updates

To ensure you don’t experience a disruption of PayPal service, we encourage you to make any applicable changes by July 7, 2015.

What do I need to do?

If you are directly integrating data from the IPN process and/or the Case report into your systems, you will need to ensure that your configuration will accept the format change for the unique dispute identifier as outlined here.

Data passed contains a case_id value. This value will now be formatted in two ways:

Existing format: PP-XXX-XXX-XXX-XXX
New format: PP-D-XXXX

For the new format, XXXX is an integer. The “D” indicates the case is a dispute.

Effective July 15, cases will be identified using either ID format until the transition to the new dispute management system is complete. This is expected to take several years.

As a best practice, merchants are encouraged to integrate flexibly so that any future changes to the unique case identifier can be made without integration changes.

When is this happening?

We will begin generating cases using the new format after July 15. To avoid any disruption to the way you process IPNs or the Case report, please update your integration by this date.

Thanks for your patience as we continue to improve our services.
