PowerToys v0.55.0 changelog


  • .NET runtime is now on 5, our next release will be upgraded to .NET 6. Moving to .NET 5 and then 6 helped reduce our moving parts in a single release so we went this route. Why this is important is this is one of the major work items needed for ARM64 support. In addition, this should help provide a speed boosts once we are on .NET 6.
