Does the Facebook Graph API have a versioning scheme?

The title says it all. I've perused the online docs, the GitHub repos, the code itself. Does any of it have a version string? (Does it really matter?)

Is Facebook Graph API deprecated?

Applies to all versions. Facebook Analytics will no longer be available after June 30, 2021. Additionally, we are deprecating the App Dashboard Plugin for Marketing API. For more information visit the Business Help Center.

How do I change my Facebook API version?

In the App Dashboard Settings > Advanced, scroll to the Upgrade API Version section.

What 3 terms does Facebook use to describe what the graph API is composed of?

The Graph API is named after the idea of a "social graph" — a representation of the information on Facebook. It's composed of nodes, edges, and fields.

Nope.

PS: SO community also requires the answer to be full of facts and complete, with some proofs and links, but in this case I cannot give a link to a documentation page that doesn't exists.
