***Invitation Week**: The release-manager curates the list of pending PRs and invites developers to organize topical working-groups (such as a "CiviMail" group or a "CiviContribute" group). All members of the core team participate in working-groups.
***Review Week**: Participants review each other's PRs. This may involve some discussion, code-review, testing, merging, or closing PRs.
