What version do I get if I use actions/checkout@v2?

[HonkingGoose]

Say I have this in my workflow file:

    steps:
      - uses: actions/checkout@v2

What does actions/checkout@v2 actually get me?
Do I get the latest in the v2 release range, or am I pinned to v2.0.0?

I've searched the GitHub docs but can't find the answer there.
Also the README for this project doesn't tell me what I'm getting.

Seems that the actions/checkout team manually updates the v2 tag to point to the latest v2.x.x release.
So when I use actions/checkout@v2 I should get the latest in the v2 release range.
