The option to the underlying pact-provider-verifier command is --provider-version-tag TAG and this can be repeated multiple times. See https://github.com/pact-foundation/pact-provider-verifier#usage
Wow, quick turn around.... thank you... I'm impressed!
Thanks! Give it a few minutes though, the change has been committed but is in the process of a release (v9.3.0").
I've just been trying this and I'm getting this error:
Error reading file from --provider-version-tag
No such file or directory @ rb_sysopen - --provider-version-tag
.. im not sure if this is related to this new feature?
Hmm, so it looks like --provider-app-version isn't available in the current binary supplied to Pact Node. Let me find out why...

OK so it looks like the standalone package needs updating as it doesn't contain this flag. I'll update that, and then update pact-node to include that in the latest binary. I have a few things on this morning, but will sort it out when I'm back a little later today.

I assume you mean --provider-version-tag ?
Yes that, I originally thought it was a documentation error and copied the
wrong tag. I didn't update the comment after it seems

Just an FYI, this release is held up a little as we investigate a minor difference in beaviour in the latest verifier. See https://github.com/pact-foundation/pact-provider-verifier/issues/42 for detail.
Ok take 2, the latest release should have this fix. Apologies for the delay.
