Downstep 1.1.0

For Mac with Apple silicon (macOS 11 or later) and for Windows 10 and 11 (64 bit).

The Mac app is not notarized: the first time, macOS blocks it. Open System Settings, Privacy & Security, and choose Open Anyway.
On Windows, unzip the folder and start Downstep.exe. If SmartScreen appears, choose More info and Run anyway.
