v0.51.0

[0.51.0] - 2026-10-28

Voice replies

• Add spoken Neo replies for the opted-in client and session; cancel pending speech on disconnect without replaying it on reconnect (#9298).
• Stream spoken reply audio from the daemon, and keep spoken replies from repeating what is already on screen (#9369, #9388).
• Queue Send while transcription is pending (#9261).
• Use explicit batch/live ASR endpoints; move recording storage and tool recovery writes off the daemon main thread (#9209, #9214, #9222).

Quote Markdown and conversations

• Render quote excerpts as Markdown, preserve the browser context menu and improve message touch targets, folding and long-message readability (#9300, #9116, #9238, #9227, #9243).
• Attribute publications to the human input being processed; bind new todos and questions to its ask (#9293, #9338).
• Search Chinese card/message text, rank Work results and open references at the exact item (#9152, #9248, #9273).

Todo status and scheduling

• Keep human-waiting todos waiting, and block completion when a required check is unmet (#9292, #9343).
• Follow through on idle workers, start dependency-ready steps under caps, and support holds and priorities (#9154, #9164, #9166, #9158, #9170, #9178, #9184, #9186).
• Show open questions in Work snapshots and collapsed cards; restore folding for completed todos and collect history in one dialog (#9226, #9205, #9239, #9253).

Database writer work

• Revoke paired devices and observe connected-device revocations without blocking the daemon; move pairing approval, redemption, creation and human reset work to DB workers (#9302, #9304, #9270, #9278, #9295, #9315).
• Move session reminders, schedules, workspaces, GitHub inbox delivery, publication pages, turn vectors and coding-ledger operations through DB workers (#9143, #9252, #9266, #9228, #9215, #9321, #9325, #9247, #9208, #9218, #9244).
• Route global and Space extension configuration, GitHub Space settings and watched-repository reads through DB writers (#9377, #9379, #9381, #9383, #9385, #9389, #9391, #9393).

Agent fixes

• Hold stalled streams until the network returns instead of failing the turn; let the query failure latch expire and park deliveries while it holds (#9375, #9371).
• Show the real dead-letter reason instead of a fixed kickoff banner (#9373).
• Pin the Copilot worker to SDK 1.0.28 / CLI 1.0.105 (#9353).
• Bound stream silence while tool calls are open; surface deferred restart, reconciliation and terminal query failures (#9284, #9285, #9110).
• Preserve model capacity across auto-compaction, stop old queries before fallback and bound repeated delivery parks (#9341, #9134, #9283).
• Prevent overlapping Desktop-owned sends, expose worker work locations and reuse idle workers at the same place (#9245, #9105, #9345).
• Fail the required CI gate when a required job is cancelled (#9311).
