I haven't read through much of it yet, but College of Lore arguably received a significant nerf in that they don't get early Magical Secrets anymore. They instead get the ability to allow people to reroll Bardic Inspiration die. Song of Rest also appears to have been replaced by the ability to allow Bards to expend Bardic Inspiration die to heal party members as a reaction, and Bards seem to always have certain healing spells prepared now.
Sharpshooter feat lost its -5 attack/+10 damage effect, trading it for the ability to cancel disadvantage when firing at close or extreme far range instead. I also don't see Archery fighting style anymore. I don't remember the Inspiring Leader feat being there before, it seems like the replacement for Song of Rest.
