General lifecycle on when staging is merged into release

[AdityaMayukhSom]

I am waiting for a feature that adds support for dotnet 9 on opensuse tumbleweed because I'm facing an issue which is solved by this PR #113548 . this has been merged into staging. I want to ask what is the general timeline before staging is moved to release branch.

Also a related question, if everyone is creating PRs to staging, are all changes then again merged to main branch too?

I want to ask what is the general timeline before staging is moved to release branch.

Releases are effectively "snapshots" for the staging branch, plus security patches that are not revealed in advance.
Usually patches are released monthly, and snapshotted about a week before the release date. The aforementioned PR was merged 3 weeks ago, so it's probably included in next monthly patch (Apr 8).

if everyone is creating PRs to staging, are all changes then again merged to main branch too?

Only main branch accepts PR. Most PRs must be first merged in main, then (selectively) backported to release/staging branch.
If there's change that not applicable to main branch, please contact the maintenance team.
