- We now use the new endpoint for loggiong in via XBox tokens (/launcher/login) - We now check game entitlements instead of only relying on MC profile presence - Accounts can now be added even when they do not have a profile - The launcher will guide you through selecting a Minecraft name if you don't have one yet
