Hi there!

We are in the process of archiving 8.0 docs since this version has reached the end of maintenance. You must remove changes to 8.0 docs since they will not exist in our main docs but will be moved to a static site.

Additionally, you'll need to "backport" your changes to version-8.3 as it was released a few weeks ago.

@Oleksiivanov Is this still a WIP and/or will you need this merged before release next week? I noticed the Connectors issue is closed.

I updated description. It can be merged (deployed) only after release (November 14). I will move to ready for review, when I update/correct this PR.
