Hi @bretg & @jsnellbaker,
Could you please merge this documentation PR to master. The publishers would then be able to access the invisibly's analytics adapter from the official site.
Let me know if any additional inputs are needed to this branch.
Regards.

Hi @Hassija

While the analytics adapter was merged into the Prebid.js master branch, it's not officially available to the general audience until the next Prebid.js release occurs (which is when someone would be able to download it off the site).

There is a Prebid.js release scheduled for later today (Dec 3), so it's likely this docs PR will be merged soon (but not before the release is out).

Please let us know if you have any questions about the above. Thanks.

Agree with what @jsnellbaker said, but will note that we may delay the release of 2.43 by a day to get the CCPA module done. After the release of 2.43, docs PRs are merged.
