Paypal IPN Broken After Update!

[dreamcatcher]

For anyone having IPN issues, looks like Paypal have updated their IPN system and something got broke:

We are aware that some merchants are currently reporting INVALID IPN responses for a large amount of transactions.

Our technical teams are working diligently to resolve the issue. We will provide updates until the issue is resolved.

Its not going down too well with some vendors.

Thanks for the heads up, all of our sites are flooding my inbox with invalid IPN notices :( Paypal has a very poor track record with testing deployments properly.
