 - `PcrEvent`/`PcrEventInputs` impl `Align`, `Eq`, and `PartialEq`.
 - Added `PcrEvent::new_in_box` and `PcrEventInputs::new_in_box`.
 - `VariableKey` impls `Clone`, `Eq`, `PartialEq`, `Ord`, `PartialOrd`, and `Hash`.
+- The traits `MemoryMap` and `MemoryMapMut` have been introduced together with
+  the implementations `MemoryMapRef`, `MemoryMapRefMut`, and `MemoryMapOwned`.
+  This comes with some changes. Read below. We recommend to directly use the
+  implementations instead of the traits.
 
 ## Changed
 - **Breaking:** `uefi::helpers::init` no longer takes an argument.
 - 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`
   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.
-- **Breaking** Exports of Memory Map-related types from `uefi::table::boot` are
+- **Breaking:** The type `MemoryMap` was renamed to `MemoryMapOwned`. `MemoryMap`
+  is now a trait. Read the [documentation](https://docs.rs/uefi/latest/uefi/) of the
+  `uefi > mem > memory_map` module to learn more.
+- **Breaking:** Exports of Memory Map-related types from `uefi::table::boot` are
   now removed. Use `uefi::mem::memory_map` instead. The patch you have to apply
   to the `use` statements of your code might look as follows:
   ```diff
-  1c1,2
   < use uefi::table::boot::{BootServices, MemoryMap, MemoryMapMut, MemoryType};

   > use uefi::mem::memory_map::{MemoryMap, MemoryMapMut, MemoryType};
