Updated my H2O e2 to the latest firmware using this patching system. Everything went well, took a while to understand how to use the kobopatch.yaml file but expect that to save lots of time on future updates.
Thanks for this new system it looks a excellent step forward.
One additional thing I would like to be able to do is replace the hyphen.en_GB file with my own custom one during the patching process. Is this possible?
