AgentMBX v0.5.0
AgentMBX v0.5.0 adds durable mailbox replay and read-only session diagnostics.
mbx_replayandagentmbx replayreturn bounded pages ordered by first mailbox visibility. Persist the returned cursor to resume across restarts or explicit provider handoffs. Completed cursors poll newly visible mail without rescanning history.- Replay preserves read and ACK state. Bodies and envelope metadata are data; use
mbx_readfor current trust and owner policy before acting. agentmbx diagnostics --mailbox NAME [--cli CLI --session ID] --jsonreports bounded, redacted mailbox, lease, queue and receipt evidence. Connector version remains unknown unless directly observed.- Live MCP handover sends a tool-list change notification so clients can discover the replay tool.
This release migrates the mailbox database to schema 3 and fences incompatible old message writers. Before activating it, pause daemon traffic and make a coherent backup. Keep the existing installation type during the upgrade, let exact-session connectors adopt the new build, then resume the daemon. See the coordinated rollout procedure. Mail, signed envelopes and ACK state are preserved; rollback requires the matching database backup and previous binaries.
Source installation and signed executable assets are distributed through GitHub. A registry npm publication is not claimed. The local console, shared topic-room delivery and interoperability extensions remain future work.
