ReOs release notes
What changed in each version of ReOs. ReOs tells you about a new version when Revit starts.
How updates reach you
ReOs checks for a new version when Revit starts. By default it downloads the update, checks its SHA-256, and installs it after you close Revit. In ReOs Settings you can have it only tell you, or turn the check off.
