 - The lifetime of the `SearchType` returned from
   `BootServices::register_protocol_notify` is now tied to the protocol GUID.
-- The traits `MemoryMap` and `MemoryMapMut` have been introduced together with
-  the implementations `MemoryMapRef`, `MemoryMapRefMut`, and `MemoryMapOwned`.
   The old `MemoryMap` was renamed to `MemoryMapOwned`.
   - `pub fn memory_map(&self, mt: MemoryType) -> Result<MemoryMap>` now returns
      a `MemoryMapOwned`.
-- **Breaking:** `PcrEvent::new_in_buffer` and `PcrEventInputs::new_in_buffer`
+- `PcrEvent::new_in_buffer` and `PcrEventInputs::new_in_buffer`
   now take an initialized buffer (`[u8`] instead of `[MaybeUninit<u8>]`), and if
   the buffer is too small the required size is returned in the error data.
