How to update the astro Binding?

I have installed the astro binding via paper UI - ist version 0.9… and gives (known) problems with triggering sunset and sunrise.
Therefore I want to update the astro binding.
But I do not know how to update a binding.
Where can I download the update? How can I install the Update?
Is it Possible via PaperUI?
Thank you

You will have to update your whole OH to the 2.2 SNAPSHOT. It appears based on another thread, that there have been changes to it that make it not backwards compatible.
