OLD PR: #4364
In the above PR I encountered multiple merge conflicts while rebasing for the DCO fix, as the branch was behind 155 commits with v3.x.x. After trying to sync with the latest changes, the conflicts became quite extensive and time-consuming to resolve. To simplify the process, I’ve created a this PR instead. Please review the PR.
