 # Changelog
 
+## v1.4.0
+
+This release contains various updates to provisioning variables and data.
+
+**Host requirements**
+
+Building firmware using this system requires `fwup` to be updated on your
+host computer to at least `v1.2.5`. The target minimum version requirement 
+has not changed from `0.15.0`.
+
+**Serial numbers**
+
+Device serial numbers are now set using `NERVES_SERIAL_NUMBER` instead of 
+`SERIAL_NUMBER`. This is to reduce ambiguity on the source of the serial
+by name spacing it along side other Nerves variables. The U-Boot environment
+key has also changed from `serial_number` to `nerves_serial_number`. The 
+erlinit.config has been updated to provide backwards compatibility for setting
+the hostname from the serial number by checking for `nerves_serial_number`
+and falling back to `serial_number`.
+
+**Custom provisioning**
+
+Provisioning data is applied at the time of calling the `fwup` task `complete`.
+The `complete` task is executed when writing the firmware to the target disk.
+During this time, `fwup` will include the contents of a provisioning file
+located at `${NERVES_SYSTEM}/images/fwup_include/provisioning.conf`. By default,
+this file only sets `nerves_serial_number`. You can add additional provisioning
+data by overriding the location of this file to include your own by setting
+the environment variable `NERVES_PROVISIONING`. If you override this variable
+you will be responsible for also setting `nerves_serial_number`.
