As for technical improvements, users are reporting shorter load times when switching channels as well as faster disc read speeds all around. The news and weather channels got some touch ups as well but most of the work seems to have gone into the shop channel which now supports a new, streamlined interface, search functions and a list of the most popular titles. Spoiler: only games featuring the word "Mario" in the title make up the top five.
A full list of patch notes may be viewed after the break.
