+Julia version 1.5 and later collects telemetry information during certain `Pkg` operations.

+This action does not alter the Julia installation in any way, therefore telemetry on your CI runs will be collected by the Julia Pkg server unless you opt out.
+In a later release of the action, an action input to opt out of telemetry will be provided but for now you need to add a step to your workflows that edits `telemetry.toml` in the CI environment as described in the [Opting Out](https://julialang.org/legal/data/#opting_out) section of the above document.
