We're changing the implementation of trust levels to use groups. Part of this is to have site settings that reference trust levels use groups instead. It converts the min_trust_to_edit_post site setting to edit_post_allowed_groups.
The old implementation will co-exist for a short period while I update any references in plugins and themes.
