* Includes new net install feature, enabled by default for Pi 4 and Pi 400
* New net install download screen may appear on boot if a boot location can't

start net install.
* New HTTP boot order.
* Bootloader diagnosis screen is now 720p if supported by your monitor.
* Self update mode is now enabled during SD/EMMC boot.
* The PARTITION number can now be specified as an EEPROM property.
* Allow smaller MSD discovery timeouts to be specified.

Now that 2020-04-16 has been released and appears to be stable move
the older binaries to and old (deprecated) directory. There's no
need to include old beta binaries in OS packages.
* Fix uart_2ndstage in the recovery.bin
* Fix missing watchdog reset if only the VL805 image is updated.
* Fix detection of VL805 EEPROM in recovery mode.
* If no EEPROM images are present then recovery.bin now renames
itself and reboots instead of treating this as an error.
The beta release with supports network boot is now stable enough
for most configurations. This is now frozen except for major bugs
in order to allow more experimental features to be released as
beta.
