The new CLI release is available at Release Duplicacy 2.2.0 Command Line Version · gilbertchen/duplicacy · GitHub.
If you’re a Web GUI user, next time you start/restart the Web GUI, it will automatically download this new CLI release and use it for every operation. You can disable this behavior by fixing the version in the ~/.duplicacy-web/duplicacy.json
file:
"cli_version": "2.1.2",
If this key has a blank value (the default), Duplicacy will attempt to retrieve the latest version available on github.
