- **BREAKING**: Original action and entry have been removed from relevant variants of `Op`. To use original action and entry during validation, they can be explicitly fetched with HDK calls `must_get_action` and `must_get_entry`. Op is passed into the app validation callback `validate` where validation rules of an app can be implemented. For update and delete operations original action and original entry used to be prefetched, regardless of whether they were used in `validate` or not. Particularly for an update or delete of an entry it is not common to employ the original entry in validation. It is therefore removed from those variants of `Op` which means a potential performance increase for not having to fetch original actions and entries for all ops to be validated.
