I love that an enemy dispenser will recharge your cloak while you're cloaked. :) It's great to camp in an enemy base waiting for the perfect time to strike without worrying about your cloak running out. About time the spy got some love with all of the sapper nurfing that took place.
The best part of the update is the spy cloak recharge; finally a spy doesn't have to waste time hiding in corners waiting for his cloak to recharge to jump back into the fight. The new teleports are cool too.
