Every Dota 2 patch Batru tracks, newest first: hero buffs and nerfs from the official notes next to measured win-rate changes from ranked matches.
7.41f, shipped September 15, 2026, is a broad balance letter patch: roughly 40 heroes and 16 items touched. The through-line is a nerf wave aimed at the 7.41e winners — Treant Protector, Bounty Hunter, Spectre, Lifestealer, Earth Spirit, Shadow Fiend, Lina, Keeper of the Light and Winter Wyvern all lose something — alongside cost hikes on late-game items (Octarine Core, Daedalus, Heart of Tarrasque) and lifesteal trims (Satanic, Mask of Madness). The buff list is short: Anti-Mage, Batrider, Chen, Disruptor, Mars, Ursa and Warlock. Measured win-rate movement against 7.41e — overall and per skill bracket, sample-gated — is in the tables below.
Winners & losers →Valve shipped gameplay patch 7.41e on July 30, 2026 alongside the Summer Scrub bug-fix wave, touching 57 heroes and a broad set of items on the eve of The International. This page shows measured win-rate movement — overall and per skill bracket, sample counts in the tables — next to the pre-patch baselines and our day-0 editorial estimates, now graded against the data: the measured numbers are the authority, and the estimates stay up, misses included, for accountability.
Winners & losers →Measured win-rate movement appears on a patch page only once enough post-patch ranked matches exist (all skill brackets); until then it shows the pre-patch baselines.
