Changes[edit | edit source]

  • Windows now supports the High Efficiency Image File Format (HEIF).
  • General improvements, changes and bug fixes listed in the official announcement.

Bugs[edit | edit source]

Mixed Reality[edit | edit source]

  • If you're using a hybrid laptop, performance of Mixed Reality may be significantly reduced.
  • Sometimes inbox apps will fail to load inside Mixed Reality and newly placed holograms may be empty. Restarting should fix both issues.
  • Sometimes it takes an abnormally long time to load the cliff house and Skyloft, and the app may occasionally restart itself while doing so.

Other[edit | edit source]

  • If you had your phone linked to your PC prior to upgrading to this build, it will become unlinked after the upgrade.
