@jaimecbernardo Are you okay with the new version file? Do we need some additional changes to add the version file to the release download asset?

[htcfreek]

Comment sounds good too. The revision 1 was only for the "using" fix.

Hi @htcfreek , added the PowerToys version next to the needed revision. LGTY?

[jaimecbernardo]

Merging so we can include in the hotfix. Other formats may be done for 0.65 if needed.
