PAYDAY 2 Winter Wonderland update is live

>New DLC tailor pack with xmas themed hats/charms/gun skins

But more importantly there is a new perk deck available called Leech:
>When activating the Leech Ampule that takes the place of your throwable, you will lose all your armor and in return, your health will get divided into between 5-10 segments. If you are not at full health, you will instantly heal up to 40% of your maximum health.
>While it’s active you can only take one segment of health worth of damage from any one source at the time. When taking damage you'll transfer health to your fellow crewmates. Your pain is their gain.
>And as the last Leech up your sleeve, the Leech Ampule can even be activated while you are bleeding out. If you are downed and activate the Leech Ampule, it will temporarily revive you. If you manage to revive a fallen crewmate or use a doctor bag, before the timer runs out, you'll keep on your feet and be able to stay in the fight.
