Release Notes## Version 4.2.2 - June 23, 2020
- **Fixed:** When using PhysicalLocation with AuthenticatedUser=Windows, intermittent "the handle is invalid" error occured while
trying to impersonate before accessing PhysicalFileSystem. This happened because the access token retrieved from WindowsIdentity
was not duplicated and when owner WindowsIdentity went out of scope (garbage collected), its access token was also being disposed.
- **Added:** StringExtensions.Truncate method.
