The Highway Code has been revised (with 8 new rules and 49 updates, to some brouhaha). Many of the changes are clarifications of existing rules, but it's still worth having a look (especially if you haven't read it since you took your driving test . . . ) since many of these are of interest to cyclists, pedestrians, horse riders and other vulnerable road users. The government website gives a rundown of the changes here
Better Ealing Streets have produced some animated videos to explain the changes here.
