- Agent sends group name (defaults to hostname) and richer metric notes (memory/disk include absolute GB values; CPU note includes system uptime) - push() accepts group param; server stores it as agent_group on deployments - Upsert key is now (company_id, agent_group, name) so two agents on the same company but different servers don't overwrite each other's CPU/Memory - Add widget config packs: linux-base, web-nginx, database-postgres/redis, docker-host, custom-cmd examples
