***Invitations**: The release-manager curates the list of pending PRs and invites developers to partner-up based on related topics (such as a "CiviMail" group or a "CiviContribute" group). All members of the core developer team will participate.
***Review Week**: Participants review each other's PRs. This may involve some discussion, code-review, testing, merging, or closing PRs.
***Test Week**: Participants install the release-candidate with realistic configurations (eg staging sites) and check that their major customizations still work. Emergency issues (regressions) may be fixed.
