   - The definition of `enum CommandEncoderError` has changed significantly, to reflect which errors can be raised by `CommandEncoder.finish()`. There are also some errors that no longer appear directly in `CommandEncoderError`, and instead appear nested within the `RenderPass` or `ComputePass` variants.
   - `CopyError` has been removed. Errors that were previously a `CopyError` are now a `CommandEncoderError` returned by `finish()`. (The detailed reasons for copies to fail were and still are described by `TransferError`, which was previously a variant of `CopyError`, and is now a variant of `CommandEncoderError`).
