TL;DRValve's Halloween update adds Halloween Cauldrons that drop Candy for a Sugar Rush buff (through November 2), plus a huge gameplay pass: a tougher Mid-Boss that drops 3 Rejuvenator crystals with a halved bounty, buffs to most lifesteal items, nerfs to Radiant Regeneration, Spirit Sap and Divine Barrier, and big changes for Solomon, Violet, Rat King, Mirage, Baba and Nurse Harrow. The 6 newest heroes are no longer marked new, so they can be banned in ranked.
Who this matters to
Everyone
The Mid-Boss has 20% more health, its bounty drops from 3000 to 1500, and the Rejuvenator now drops as 3 crystals that each take one heavy melee. Halloween Cauldrons are in matches through November 2.
Lifesteal and sustain builds
Bullet Lifesteal, Spirit Lifesteal, Infuser, Leech, Vampiric Burst and Fury Trance all get buffs, while Radiant Regeneration's heal on ability cast drops from 65 to 40 and now only triggers in combat.
Solomon, Violet and Rat King players
Solomon's base bullet damage drops from 30 to 25 and Develop Queen's cooldown rises to 240s, Violet's Still Life stun drops to 0.9s and Abstract Landscape's cooldown rises to 180s, and Rat King's Scrap Grenade and Rule, Ratannia! are toned down.
