October 27, 2026

What's new#

Fixed#

  • A friend with an offline account can join your world through Play Together. The world checked every joiner's Microsoft sign-in, so a friend without one was turned away with "Invalid session, try restarting your game". When you play with an offline account yourself, your world no longer asks for it. This works on Minecraft 1.14 and newer; 1.8.9 to 1.13.2 will follow.
