+# ForgeFlow 0.10.8
+
+## Self-contained checksum verification
+
+- Binary and source update helpers no longer depend on the optional PowerShell `Get-FileHash` cmdlet.
+- Both helpers calculate checksums directly with the built-in .NET SHA-256 implementation.
+- A real Windows regression test clears `PSModulePath` and verifies the downloaded binary successfully in that minimal environment.
+- The helper still validates the exact published checksum before waiting for ForgeFlow to exit or changing installed files.
+- This release retains the reliable non-detached launcher and server-to-repository recognition improvements from 0.10.6 and 0.10.7.
