There is a 60 day grace period and DMs should use the new material.
It has always been the Adventurers League’s policy to use the most recent version of the rules when they have been updated. This applies to the 2024 rules revision in the following ways:
- When a new core rulebook is released worldwide, Adventurers League games will use the updated 2024 rules found in it.
- Until a 2024 core rulebook is released, continue to use the rules from its 2014 counterpart.
- If a rules option appears in a previously published sourcebook such as Tasha’s Cauldron of Everything or Xanathar’s Guide to Everything and was updated in the 2024 rules, use the updated rules.
- If a rules option appears in a previously published sourcebook and has not been updated in the 2024 rules, continue to use the most recently published version of that option.
