+      - [Smart Placement](/workers/configuration/smart-placement/) no longer runs Workers in the same location as D1 databases they are bound to.

       - When Workers generate an "internal error" exception in response to certain failures, the exception message may provide a reference ID that customers can include in support communication for easier error identification.  For example, an exception with the new message might look like: `internal error; reference = 0123456789abcdefghijklmn`.
