WinFsp 2023 has been released. This is a major version upgrade from v1.0 to v2.0. There are many improvements, but most importantly the v2.0 series of WinFsp will no longer require rebooting after upgrading.

Note that the installer will sometimes claim that a reboot is required, even when it is not. Rest assured that no reboot is required; this message comes from somewhere in the internals of the Windows installer and/or the restart manager and I have been unable to suppress it.
