The documentation states projections are still beta

Do you have an ETA on when this will be production ready?

Hi Ananda, thanks for pointing out the documentation issue, please open an issue for that under the docs github and we will attend to it as soon as possible.
Projections are expected to be released out of beta with the release of 4.0.0.

Thanks for the response. When in 4.0.0 expected to release?

fairly soon, it is a big release so its been slow to move with a lot
of testing. There are daily packages available already
