DM 0.6 — groups

DM 0.6 implements organization groups across storage, authorization, HTTP, WebSocket delivery, the Rust SDK, local runtime, CLI, browser and diagnostics.

• Named groups have descriptions, explicit invitations and IAM tag policies.
• Public groups include organization Carbons; Silicons require invitations.
• IAM-disclosed administrators and owners manage groups and invitations.
• New members can read full prior history. Removing access stops future reads, writes, private-draft access and delivery replay.
• Existing direct conversations retain their sealed participant sets.
• HTTP v1, WebSocket v3 and shared transport v1 remain unchanged. Group metadata and group endpoints are additive.

Use the groups guide for commands, SDK methods and access rules. The migration is 0020_groups.sql; rerun deploy/runtime-grants.sql before rolling out API and worker binaries. Deploy the gateway route allowlist together with the browser release. CLI and Rust packages use version 0.6.0.
