2XKO recently got its final content update that added two new characters, lots of new cosmetics, features, and many other improvements, but now it's time for the actual final update.
It is largely focused on tweaking the balance and polish up the few quirks. Obviously balance is never quite perfect, but what matters is that the game is left in a good state without any egregious issues.
If you want to read all the changes, you can find them on the official website. The balance patch doesn't affect the whole roster, but offers just a few pointed changed for Akali, Braum, Lux, Samira, Senna, Sett, Thresh, and Yasuo, with a few of them only getting small bug fixes.
However, another huge change that's coming with this patch is you'll no longer need Vanguard, Riot's homemade, kernel level anti-cheat solution, to run or install the game. This should make it much easier for the community to take full control of the game, and tweak it in any way they want going forward.
