Age of Sigmar isn't the only game that's getting a bit of an update from Games Workshop. 40k is also on the list of games that are getting tweaked. In this case, it's the game's points update. You can download your copy now.
From the article:
You may remember back at Warhammer Fest we announced that all points updates for Warhammer 40,000 would be made available as free digital downloads from now on. Well, that time has arrived, and we’re glad to announce that the Munitorum Field Manual 2022 MkII is available to download – right here, right now.
For those of you new to the Warhammer hobby, these updates replace the information found in your codex, and provide a complete, up-to-date list of points values for all units in the game. These points updates are now freely available online for all Warhammer hobbyists, so you can pick them up as soon as they’re released.
