What is new in Unison UI 0.10.1
# Unison UI for macOS 0.10.1 Version 0.10.1 is a maintenance release. It stops the bundled command-line tool and sync engine from leaving coverage files behind, and it adds an offline copy of this app's user manual to the Help menu. Existing profiles and settings continue to work without migration. ## Fixed - **Release builds no longer leave `.profraw` files behind.** Earlier builds carried code-coverage instrumentation that wrote a `default.profraw` file to the working directory when the bundled `unison` command or its `-server` role exited, including on Macs used as synchronization peers. That instrumentation is removed from release builds, and the release pipeline now checks the shipped binaries to keep it out. - **Help opens an offline user manual.** Help now opens a copy of this app's user manual bundled with the app, so it works without an internet connection and always matches the version you are running. It includes the corrected command-line session documentation. The separate upstream Unison reference manual is unchanged.
