Features

Adds a Web Shell sidebar activity view for trusted workspace conversations, showing approval/input/error states, unread completions, running work, and bulk read/archive controls. (#16022) by @deggs7
Adds an "Add to Split View" option to eligible sidebar session menus in web shell, making it easier to open sessions side by side. (#15956) by @4ekuct25
Adds request success rate, output speed, per-model success indicators, and distinct model colors to the Web Shell token usage panel. (#16108) by @qqqys
Web Shell composer shows a dismissible Workflow chip that turns Workflow mode off, warns when tools are unavailable, and summarizes the mode in the + menu. (#16107) by @qqqys
Web Shell Token Usage now plots per-request output speed, first-token latency, and failure details by model, making session performance and errors easier to inspect. (#16111) by @qqqys
With experimental.unifiedAgentLoop enabled, more ACP turns, including channel prompts and Goal-proposal approvals, run on the shared loop. (#15902) by @qqqys
Mods can now run prompt.submit hooks in headless runs for -p prompts and stream-json user messages, allowing prompt inspection or rewriting before submission. (#15905) by @qqqys
Desktop releases now publish Fedora 44 and RHEL 10 x64 RPM installers alongside existing Linux packages. (#16060) by @yiliang114

feat(ci): let the PR review canary cohort carry its own endpoint (#16130) by @yiliang114

Bug Fixes

OAuth refresh lock cleanup now removes the lock only when the current process owns it, preventing exiting processes from deleting active refresh locks. (#15661) by @2SinceJuly
MCP tool discovery now skips duplicate tool names but keeps all uniquely named tools, preventing one name collision from hiding an entire server's tools. (#15757) by @2SinceJuly
The Web Shell Plugins page now shows a back control when the navigation rail is unavailable, letting users return to chat from compact layouts. (#15651) by @2SinceJuly
LSP code-navigation queries now fail with an explicit reason when no language server is ready instead of returning empty results. (#15946) by @404khai
The verify report now counts targeted gate test-suite results separately from a round's scripted assertions, making assertion totals reflect only round checks. (#16013) by @wenshao
Makes long /btw answers scroll in a bounded panel with mouse wheel, Shift+Up/Down, PageUp/PageDown, and a scrollbar, while short answers remain unchanged. (#15982) by @2SinceJuly
Fixes verify-pr to count each suite run as one assertion and handle skip notices on closed PRs so review rounds are not rejected with zero assertions. (#16050) by @wenshao
Fixes Kimi K3 generation recognition so supported IDs use the 1,000,000-token context window, while k3-256k keeps its 256K window. (#16048) by @wenshao
Fixes review command so plain-language re-review requests target the intended PR and do not misread resume flags or file-like tokens. (#15998) by @wenshao
Installs DejaVu fonts in the sandbox so capture cards use the intended monospace font and render legibly. (#16032) by @yiliang114
Moves the Workflow mode toggle from the composer toolbar into the composer “+” menu to reduce toolbar clutter while keeping it accessible. (#16047) by @qqqys
Improves managed-agent recovery accuracy by blocking gap fills without child ledger evidence and clarifying unknown or never-started states. (#16015) by @wenshao
Fixes managed-agent child result delivery status so consumed child results are no longer marked pending. (#16074) by @wenshao
Fixes AI attribution notes for loosely spelled git commit --amend commands so they diff against the amended commit, not earlier commits. (#16073) by @yiliang114
Makes loop-protection reminder delivery and telemetry settle only when the model request carrying the reminder is accepted, preventing premature clearing or logging. (#15559) by @suzhiguo7
fix(core): don't treat fd duplication (2>&1) as a file write in shell permission checks (#15681) by @Suaroman
Sanitizes goal approval text and edit-diff file paths in Web Shell by escaping control and bidi characters so displayed approval content cannot carry hidden controls. (#16080) by @yiliang114
Shows Managed Session list failures as a localized Retry notice with request details and avoids the empty state until loading succeeds. (#16082) by @yiliang114
Fixes invalid Javadoc left after the module split so the managed-agent release profile can build documentation again. (#16099) by @doudouOUC
Moves the Web Shell managed session list failure notice below the Sessions / Archived tabs and prevents its request id from being cut off. (#16104) by @yiliang114
Fixes qwen-managed-agent-upgrade start and verify so they reach the control plane and Hosted Harness using the server's resolved endpoint configuration. (#16051) by @wenshao
Tightens the Web Shell mobile composer layout by aligning workspace controls, truncating long names, and centering the context-usage ring. (#16103) by @ytahdn
VS Code companion session history now groups This Week by the current calendar week, so earlier sessions are placed in Older instead of incorrectly appearing under This Week. (#16097) by @yiliang114
The bundled review skill now tells fetch-pr to re-run with both --since and --since-model and removes the retired range model, preventing incomplete anchors. (#16094) by @yiliang114
The Managed runtime release workflow can now rebuild the missing 0.26.5 runtime from its original tag after repairing the Javadoc issue that blocked the release. (#16114) by @doudouOUC
Windows installer updates now stop the bundled runtime before replacing files, reducing update failures when node.exe remains locked. (#16071) by @yiliang114
Channel users can now /approve or /deny their own pending one-time tool permission requests in the current attended turn. (#16087) by @BenGuanRan
