Hi I have upgraded Cerbos image to 0.43.0 on one of our services (it runs as a sidecar with one of our services), but service uses the save version of cerbos sdk as before the image upgrade. Does it mean that I need to upgrade the cerbos sdk too?

Hi, nope, the SDK is generally backwards and forwards compatible with different versions of the PDP, so you don't have to upgrade them at the same time. Sometimes when features are added to the PDP you'll need to upgrade the SDK to take advantage of them, but we try to avoid breaking API changes wherever possible.

Thank you!
