Recent Changes to Drivers Hours Rules

I’ve been off work since just before Christmas and ‘out of the loop’,so only just heard of some recent changes to the hours rules. Are they anything major and does anyone know of a website that lists them all accurately? Or of course any other topics on here cos I can’t seem to find any. Cheers.
