+### Added
+- Serial/USART: The `Baudrate` type for more precise control over the baudrate
+  selection ([#88]).
+
+### Changed
+- The constructor for the `Serial`/USART driver must now be called with
+  a `Baudrate` value, not an integer ([#88]).  In practice, the easiest way to
+  do this is using the `.into_baudrate()` conversion method.  As an example, the
+  needed change might look like this:
+  ```diff
+   let mut serial = arduino_uno::Serial::new(
+       dp.USART0,
+       pins.d0,
+       pins.d1.into_output(&mut pins.ddr),
+  -    57600,
+  +    57600.into_baudrate(),
+   );
+  ```

 ## [2020-10-26 - 2020-11-01][2020-44]
+### Added
+- Support for `ATmega328PB` ([#96]).
+
 ### Changed
+- `atmega328p-hal`: You must now select a chip via either the `atmega328p` or
+  `atmega328pb` features.  Selecting no or more than one chip will lead to
+  a compile-error.  As an example:
+  ```toml
+  [dependencies.atmega328p-hal]
+  git = "https://github.com/Rahix/avr-hal.git"
+  rev = "<latest git commit hash>"
+  features = ["atmega328p"]
