When the respository is added as an extension source, each extension loaded is the Latest version of that extension step or resource.
To release a properly Git tagged resource or step, hover over the rightmost region of its row to reveal the Release icon, then click it.
In the subsequent Release Extension dialog, select the release tag from the dropdown, then click Confirm.
Once confirmed, the version will be listed among the Released extensions.
The released version of the resource will now always be available to users by that version number, even afer a newer version is synced from the extension source.
Extensions can be retired from use on a specific date. Details of this procedure are described in Managing Pipelines Extensions.
