This is the first stable release with Pi zero 2W support.
If you have previously tried Beta42 to Beta49 you are strongly urged to upgrade to this version as the official raspberry Pi boot firmware included in those beta releases had a bug that slightly overvolted the Pi zero.
Raspberry Pi have since fixed this bug and the new stable release includes the bug fixed boot firmware.
There is a new stable software release available: https://github.com/hoglet67/RGBtoHDMI/releases
