What does the "id" refer to in the JSON representation of a release?

Hi there – when I query for a release using GraphQL, I can get back results like this:

       "node": {
          "name": "v1.....8",
          "publishedAt": "2021-....26Z",
          "isPrerelease": false,
          "tagName": "v1.....8",
          "tagCommit": {
            "abbreviatedOid": "0a...35"

That abbreviatedOid corresponds to the commit shown for the release on the GitHub release page.

When looking at that release as returned by /repos/..../${REPO}/releases?per_page=100&page=${PAGE}” I see a numeric "id": value. Does that correspond to anything in git?
