The update from version 21.3.3 to 21.3.4 contains breaking changes

[primeos]

FYI: I wouldn't expect breaking API changes in a patch release (even if this project doesn't use semver). This apparently makes version 21.3.4 incompatible with https://github.com/intel/media-driver version 21.4.3. Is that really intended?

Michael Weiss,

This was intended as it is an ABI break(See #92)
. To support gmmlib.21.3.4, media latest release is expected. Since Gmmlib changes always go first, this is expected to fail. This will be soon stable once media releases.
However, If you want to get the things moving temporarily, media patch 42ffd79 will do the job for you.

Thanks,
John

Sure, but IMHO fairly obviously API breaking changes should have changed major, or at even minor release version, not just patch level version. That's against all versioning practices. You should have tests that catch API/ABI changes unless there's large enough version bump.

Agreed. This should be much better now, upstream was kind enough to change their versioning scheme (but it was only announced in the other issue): #92 (comment) :)
