Got any Badgers concorded lately, Mang?
Anyways, to add to what these guys have already said:
When Nikolai said they "rebalanced" T3C's he means they gutted them except the Loki which is now the superior choice for almost all the things you'd use a T3C for. The Tengu is essentially a weaker Loki. The Proteus' only use is as a 1km blaster armorbrick for PIRAT gate/station games and the legion is "man I wish I was in a Loki right now". There's also a ton of minor tweaks to the game, like some T1 frigates and cruisers got a balance pass. Most got buffed (omen, bellicose, arbitrator, stabber), one got nerfed rather heavily (vexor) and then there's some up for debate like the rifter (it's still meh) which may all be relevant for a purple fleet. Omen is especially great now in my opinion for a roaming fleet.
Command destroyers are the only new ship type that've been added and they have a module that will microjump everyone nearby 100km in the direction they are facing (except scrammed targets and capital ships). Of course not usable in highsec because that would be too fun and we can't have any of that nonsense.
Alpha clones can fly all race's T1 battlecruiser and battleships now and have acces to all T2 weapons except large guns/missiles which are still restricted to T1 (as if it really matters). They have pretty decent support skills too. Yes they can fly machariels.
They doubled the fuel requirement for jumping (and cut the volume of isotopes in half, plus added more capacity for the fuel bay) which may slightly impact some specialized purple fleets.
CCP introduced some garbage "fleet PvE" content that everyone already forgot about probably. Could have been great for purple fleets but they dropped the ball pretty hard there.
Not relevant to purple fleet but may be interesting to know: plex got split into 500 pieces (and you need 500 newplex for a month of gametime). This plus inflation makes it so that plexing your account currently costs something along the lines of 1.6 billion.
They added an extremely annoying chat bubble to the pilot list in your chat windows that immediately starts a conversation with the pilot when clicked upon. Nobody asked for it and everyone complained about it but they still put it in the game. Expect a lot of accidental conversations coming your way when they just want to take a look at your profile.
