Artifacts like generated Markdown files now open in the Files tab alongside repository files, with a switcher to move between them and an option to promote an artifact into the repository.
Custom agents that share a display name across plugins are now distinguished in the agent picker by their owning plugin.
Renamed the "Start from scratch" option to "Chat" in session creation menus and project pickers.

Fixed 22

Fixed a bug where finishing a background session could pull you away from the session or grid you had since selected.
Fixed an issue where a new remote session could get stuck indefinitely on "Preparing worktree" or "Preparing project".
Fixed an issue where a valid agent response with no visible reply could incorrectly show a "No response was returned" error.
Fixed an issue where resuming a session could stall for up to 60 seconds when other sessions were resuming at the same time.
Fixed Cloud session responses sometimes stopping early and dropping later message content.
Fixed crashes in the code editor and table editing when working with certain scroll positions and markdown tables.
Fixed inconsistent spacing on the pending reviews indicator dot in the pull request overview.
Fixed keyboard focus being lost after hiding a repository from the sidebar when its group was first in the list
Fixed pressing the right arrow key after the last cell of a Markdown table in the message composer, so typing continues after the table instead of staying stuck inside it.
Fixed pull request and check status details sometimes failing to load on GitHub Enterprise when check app metadata was inaccessible.
Fixed repository avatars not loading for GitHub Enterprise Server accounts in Quick Open, and reduced the delay before suggested repository avatars appear.
Fixed sidebar session names continuing to scroll after the pointer leaves a row that remains focused, such as after clicking or dragging a pinned session.
Fixed the /agent autocomplete in the prompt composer showing identical entries for plugin agents that share the same name; it now labels them with their owning plugin so you can tell them apart.
Fixed the # and @ mention menus showing "no results" when a lookup actually failed. They now show a clear error message with a Retry button instead.
Fixed the Add tab button sitting flush against the edge in empty panes so it now aligns with the same inset used elsewhere.
Fixed the Reviews tab count sometimes disappearing on a pull request after new comments loaded.
Long or multiline answers to ask-user prompts are no longer truncated into a single line; the full response is now shown with its original line breaks.
Restored Shades of Purple's authored syntax highlighting colors in the diff and code views.
Terminal text now automatically adjusts contrast against colored backgrounds so it stays readable in every theme.
The "Send now" button on queued messages now matches the composer's send button styling, with a compact appearance and a larger clickable target.
The @, #, and & mention menus in the prompt composer no longer disappear silently when a search finds no matches; they now show a "No results found" message that's also announced to screen readers.
Undo and redo now work reliably in the Markdown editor when switching between Live and Code modes.

GitHub Copilot CLI 1.0.84-5

GitHub Copilot CLI

Prerelease

Released: 11 Sep 2026
Changes: 20

Added. Improved. Fixed.

Key changes

Add session and memory import commands for the semantic JSONL interchange format
Shell completions are generated from the same grammar the CLI parses with, so copilot <TAB> offers root flags alongside subcommands and each subcommand offers only its own options
Command-line parsing moved from Commander to a Rust grammar; error and help wording changed, copilot login --host now works, and --max-autopilot-continues no longer accepts scientific notation
Show /sandbox filesystem paths as absolute paths; typing ~/path still expands to your home directory

Fixed same-turn MCP tool-list refresh after received change notifications, including modern subscription-based servers.
The remote session timeline entry now advertises ctrl+o to show or hide the QR code, matching the key that actually toggles it

The "/autopilot" command now sets a persistent objective, just like "/goal", instead of only switching the session mode.
The session utility rail now shows three items per section before revealing more, so more sections fit on screen at once.

Retrying a failed canvas extension check no longer shifts the layout of the Installed extensions list.
Session mentions in the composer and chat now show consistent icons and live status indicators, matching their appearance in the sidebar.
The Dim color variant in Settings → Themes is now only offered for GitHub Dark, so it can no longer be applied to GitHub Light or an external palette where it doesn't render correctly.

GitHub Copilot CLI 1.0.84-2

GitHub Copilot CLI

Prerelease

Released: 8 Sep 2026
Changes: 14

New. Improved. Fixed.

Key changes

Vim mode is now available to everyone. Turn it on with /vim or by setting editorMode to vim for modal editing in the composer, with the current mode shown while you type.
On supported Windows sandbox policies, interactive shell commands now record blocked accesses. One approved escalation retries with file and process restrictions recording instead of blocking while network policy remains active, then falls back to the disclosed full bypass only if still blocked
Speed up startup when resuming an existing local session by its exact UUID with --resume
ctrl+h no longer deletes a whole word in tmux, screen, and remote sessions that carry a Windows Terminal WT_SESSION from elsewhere. As an accepted tradeoff, ctrl+backspace now deletes a single character in those sessions — including a genuinely local Windows tmux or screen pane — where ctrl+w still deletes a word

The Run button's tooltip and accessible name now show the default script it will run when multiple run scripts are configured.
Typing /fleet in front of a prompt in a new, unsent chat no longer refuses the message with a remote-host error — it starts the chat as a Fleet, matching Home and workspace drafts.

All 19 changes

Features 11

cancellation for host-owned external tools — Host-owned external tool callbacks are now cancelled when their runtime request completes or their SDK session terminates. The cancellation primitive is idiomatic per SDK: .NET passes a request token to AIFunction, Node.js exposes ToolInvocation.signal, Go cancels ToolInvocation.TraceContext, Java cancels the returned CompletableFuture, Python cancels the handler task, and Rust drops the handler future. Go handlers that retain TraceContext for background work must derive a separate lifetime because the invocation context is cancelled when the request ends.
declare application identity with client info — Client options now accept optional client info (application name and version, integration name and version) across all six SDKs, exposed idiomatically per language (clientInfo in Node.js, client_info in Python and Rust, ClientInfo in Go and .NET, setClientInfo in Java). When set, the SDK forwards it on the server.connect handshake so the telemetry the runtime emits on the connection is attributed to the application and its Copilot integration instead of the runtime's own build. All fields are optional, and leaving client info unset keeps the runtime's default attribution. See Client info.
Node Agent Factories pagination and run notifications — The experimental Node.js Agent Factories convenience API now supports paginated run history. Existing session.factory.listRuns() calls still return the runs array, while calls with afterSeq, beforeSeq, or limit return the full page with cursor and truncation metadata. Factory run and resume options now accept notifyOnComplete and logPhaseNames. The SDK forwards these options to the Copilot CLI for new and resumed runs.
selectable ask_user session behavior — Session create and cold resume now accept a language-specific askUserVariant option with legacy and elicitation values. SDK sessions retain the legacy question-and-answer tool by default. Select elicitation and provide an elicitation handler to expose the structured form-based ask_user tool.
rotating session-scoped GitHub credentials — All six SDKs can now acquire short-lived GitHub credentials through a session-scoped callback. The SDK registers the callback before session create or resume, maps initial and refresh requests to the owning session, and removes registrations on rollback, replacement, session close, and client close. Static per-session gitHubToken credentials remain supported and are mutually exclusive with the callback. Token responses use the shared tagged token/cancelled shape and require expiresIn, expressed as the positive number of seconds remaining when the callback completes. See github/copilot-agent-runtime#16381 for the runtime credential-authority implementation. Initial acquisition occurs during create or resume; cancellation, callback errors, and invalid credentials reject that operation instead of falling back to ambient authentication. Idle sessions refresh only before their next credential-consuming operation.
extensions can request sensitive environment variables — Copilot CLI extensions can now ask for named sensitive environment variables when they join a session. joinSession() accepts a requestedEnvironmentVariables option listing the variable names the extension needs. The CLI shows a permission prompt naming the extension and the exact variables requested. On approval, only those variables reach that extension and their values are written into the extension process's process.env before joinSession() resolves. On denial, joinSession() rejects, the extension does not load, and its tools never reach the model. An approval is remembered against the exact set of names the user saw, so an extension that later asks for one more variable prompts again. Names that are unset, or that the CLI does not filter from extensions, are not prompted for. This is the client half of the feature; it requires a Copilot CLI that supports extension environment access, and older CLIs ignore the request and grant nothing.
early session-event subscription (Rust) — The Rust SDK can now observe every event routed to a session, starting with that session's very first routed event. Client::prepare_session and Client::prepare_resume_session return an inert PreparedSession that owns the session's event channel, so a subscription can be installed *before* any protocol activity begins: Previously, Session::subscribe could only be called on the returned session, so events the runtime emitted while session.create / session.resume was still in flight were broadcast with no receiver installed and dropped. Ephemeral events such as session.idle are not persisted, so they could not be recovered with getMessages either. The guarantee is scoped to *routed* events. For cloud sessions where the server assigns the session ID, the SDK cannot route notifications until the session.create response arrives and the ID is known, so events emitted before that point are not routable to any session. Pin session_id on the config to get router registration before the RPC, and with it complete pre-response coverage. prepare_* is synchronous and inert: it validates the buffer capacity and allocates a local channel, and performs no router registration, task spawn, or wire activity until start() is first polled. start(self) consumes the handle and PreparedSession is not Clone, so a prepared session can never produce two event loops. Dropping an unstarted handle leaves no state behind; dropping a polled start() future cancels the startup and unregisters the session, so a retry with the same session ID succeeds. Session registrations now carry an ownership identity, so cleanup removes only the exact registration it owns and an abandoned startup can never evict a same-ID retry (or a session that replaced it). Both SessionConfig and ResumeSessionConfig gained a runtime-only event_buffer_capacity option (default 512, Some(0) rejected as an invalid config). The buffer is finite, so slow subscribers observe Lagged rather than applying backpressure; consumers that need a lossless view of a large startup burst must size the buffer accordingly or drain concurrently with start(). create_session and resume_session are unchanged wrappers over prepare_*(...)?.start() with identical RPC sequences and error kinds.
host-injected managed settings permissions — Session create and resume accept a new optional managedSettings option that injects an enterprise permissions policy at session startup, alongside the existing enableManagedSettings self-fetch flag. The current contract is permissions-only: disableBypassPermissionsMode (the literal "disable"), plus deny, ask, and allow rule lists. The layer composes restrictively with any server- or device-level managed settings (deny/ask are unioned, every present allow list must admit a tool, and disableBypassPermissionsMode is deny-wins). This layer is startup-only and is not persisted with the session, so it must be re-supplied on resume to remain in effect; omitting it on resume clears the previously injected layer. It can be combined with enableManagedSettings. Host injection requires Copilot CLI 1.0.79-5 or later and does not require an SDK protocol version bump. The generated session-event types also expose truthful injected-policy provenance: session.managed_settings_resolved can report source as client or mixed, with optional clientManaged metadata.
Auto model routing tier controls — Sessions can now steer auto model routing toward efficiency, balance, or intelligence. An Auto tier can be set at session creation, and a new setAutoTier (and equivalent setModel option) lets sessions stage or reset a tier preference afterward, since the runtime only commits a staged preference on the next successful auto model turn. (#2437, #2514)
sandbox bypass and non-object external tool arguments — Sandbox configuration now exposes allowBypass across all six SDKs. External tool overrides such as apply_patch can also receive non-object JSON argument values, which previously failed before reaching the host handler in .NET. (#2372, #2496)
host-resolved feature flag overrides — Session create and resume now accept a featureFlags map across all six SDKs, forwarding host-resolved overrides while preserving the distinction between an unset map and an explicitly empty one. (#2451)

A session lock that is re-entered on the same thread now fails with a reported error instead of freezing the CLI.
Kerberos proxy authentication reconnects when the initial challenge answers with Connection: close
Sandboxed gh commands now authenticate as the account configured for the repository instead of the Copilot CLI login
MCP tools remain callable after MCP server restarts
Sandboxed file tools now read the same developer-tool paths as sandboxed shell commands, including token-bearing registry config such as ~/.npmrc; set sandbox.allowDevToolAccess to false to turn these grants off
Stopping a timed-out shell command now lets queued messages run and sessions return to idle
A follow-up prompt typed while autopilot is running no longer disappears from the timeline
Restart provides clearer update guidance when automatic restart cannot be completed
MCP servers configured by your agent stay available after built-in sub-agent turns.
Anthropic sessions continue after temporary fallback instead of failing on invalid thinking signatures
Long-running sessions on Linux return freed memory to the system instead of holding gigabytes of it
Enterprise-denied MCP servers can no longer start before the managed allow/deny policy resolves; server startup now waits for the managed-settings fetch instead of racing it
Host-provided plugin customizations can be read without redundant path permission prompts
A relative --add-dir or --plugin-dir path now resolves against the session's working directory under --resume=<id> and --worktree, instead of the directory the CLI was launched from. Relative values are also resolved after -C is applied, so -C no longer has to precede either option on the command line
MCP servers contributed by a plugin are no longer labelled "User" in the MCP dashboard, and a server from a bundled plugin is now shown as built-in and names the plugin it came from.
The newest line of output stays visible above the input box instead of hiding behind it, except while a prompt is pinned to the top of the transcript
Exporting a resumed session with --share or --share-gist writes the whole transcript instead of only the latest run
On macOS and Linux, sandboxed commands can no longer reach services running on your machine. On macOS this also blocks a server the command itself starts on 127.0.0.1, so test suites that bind a local port will fail; turn on Allow local network in /sandbox to reach localhost again.
Linux sandboxing now needs slirp4netns, nsenter, iptables, ip6tables, iptables-restore and ip6tables-restore on PATH. Install them if sandboxed commands start failing to launch.
CLI starts without the interrupted-session restore prompt by default.
Resuming large sessions keeps the input prompt responsive sooner.
Linux sandboxes now restrict network egress to the configured proxy; proxy mode requires slirp4netns, util-linux 2.35+, iptables, and /dev/net/tun access
/mcp config and the MCP add/edit/authenticate forms now open in the plugins dashboard instead of a separate MCP manager, so closing a form returns to the server list.
File path autocomplete stays fast in large repositories
Plugin list commands and /plugin now show bundled built-in plugins.
Improve sandboxed Bazel and Bazelisk runs by granting required cache and output paths; macOS requires a future Bazel release or additional sandbox capabilities
The collapsed autopilot goal panel now reads as a single-line pinned prompt, keeping the frame it shares with a pinned prompt instead of compressing into a bare band wedged against the chrome above it

Prerelease

Released: 1 Sep 2026
Changes: 14

Features. Other changes.

Key changes

rewind support across all SDKs — Sessions can now opt into file-change tracking and rewind conversation history and tracked file changes to any prior checkpoint.
session-scoped GitHub token providers — Sessions now support expiry-aware GitHub token callbacks in addition to static tokens.
Java in-process native runtime on all platforms — The Java SDK now ships a bundled in-process Copilot CLI runtime for Linux x64/arm64, Windows x64/arm64, and Apple Silicon macOS.
managed SDK servers now use the Rust runtime wrapper — All six SDKs now spawn the dedicated copilot-runtime executable when managing their own subprocess connection, pairing the wrapper with the correct runtime.node addon for a leaner and more reliable process lifecycle. (#2395)

Features 10

rewind support across all SDKs — Sessions can now opt into file-change tracking and rewind conversation history and tracked file changes to any prior checkpoint. Enable file tracking when creating a session, then use rewind to roll back. (#2321)
session-scoped GitHub token providers — Sessions now support expiry-aware GitHub token callbacks in addition to static tokens. The SDK handles refresh requests from the runtime, so extensions always receive fresh credentials. (#2412)
Java in-process native runtime on all platforms — The Java SDK now ships a bundled in-process Copilot CLI runtime for Linux x64/arm64, Windows x64/arm64, and Apple Silicon macOS. No separate CLI installation is needed on these platforms. (#2301, #2393, #2402, #2421, #2427) The correct native classifier is resolved and loaded automatically at runtime — no configuration needed.
managed SDK servers now use the Rust runtime wrapper — All six SDKs now spawn the dedicated copilot-runtime executable when managing their own subprocess connection, pairing the wrapper with the correct runtime.node addon for a leaner and more reliable process lifecycle. (#2395)
built-in plugin directory support — Host applications can now register trusted built-in plugin directories loaded before any session begins. Unlike ordinary --plugin-dir loading, these are registered via plugins.builtin.set and trusted by the host. (#2330)
permission decisions can carry decision context — Permission handlers can now attach optional decisionContext when replying to a permission request, letting the runtime attribute decisions to a person, host policy, or automated recommendation. Additive for all SDKs except Rust. (#2294) > Rust breaking change: PermissionResult::Decision changed from a tuple variant to a struct variant ({ decision, context }). Code using result helpers (approve_once() etc.) is unaffected; direct construction or pattern-matching on Decision requires migration.
extensions can request sensitive environment variables — joinSession() now accepts an env option listing the sensitive environment variable names the extension needs. The CLI prompts the user; on approval the values are written into process.env before joinSession resolves. (#2348)
ClientMode::Empty now excludes built-in skills by default — When a session is created in empty mode, includedBuiltinSkills defaults to [] across all SDKs. Pass an explicit allowlist to opt individual built-in skills back in. (#2410)
agent factories — argsSchema, pagination, and completion options — Three improvements to the Agent Factories API in the Node SDK:
- Declare an argsSchema on a factory so the CLI validates arguments before a run starts (#2315)
- session.factory.runs.list() supports cursor-based pagination for browsing full run history (#2431)
- Run and resume options now forward completion notifications and phase-name logging (#2431)
ask-user variant session option — All SDKs expose an askUserVariant option on session create and resume for structured ask-user tool behavior. Omitting it preserves legacy behavior. (#2432)

bugfix: [Rust] prevent orphaned CLI processes when the client is dropped (#2292)

GitHub Copilot SDK

Prerelease

Released: 1 Sep 2026
Changes: 14

Features. Other changes.

Key changes

rewind support across all SDKs — Sessions can now opt into file-change tracking and conversation rewind.
session-scoped GitHub token providers — Sessions now support a dynamic, expiry-aware GitHub token callback as an alternative to a static gitHubToken.
built-in plugin directory support — Applications that ship their own built-in plugins can now register a trusted plugin directory at client startup.
permission decision context forwarding — Permission handlers can now attach a decisionContext so the runtime can attribute whether a decision came from a person, a host policy, or an automated recommendation.

$ gh release view v1.0.13-preview.3 --repo github/copilot-sdk

All 14 changes

Features 6

rewind support across all SDKs — Sessions can now opt into file-change tracking and conversation rewind. When enableFileChangeTracking is enabled, the session records which files were changed during a conversation turn. You can then list pending rewind points, preview changes, and rewind the conversation history together with any tracked file modifications. (#2321)
session-scoped GitHub token providers — Sessions now support a dynamic, expiry-aware GitHub token callback as an alternative to a static gitHubToken. The SDK maps each host request (with host, session, and reason context) to your callback, handling concurrent-session isolation automatically. (#2412)
built-in plugin directory support — Applications that ship their own built-in plugins can now register a trusted plugin directory at client startup. These plugins are registered with the runtime before any sessions are created, distinct from ordinary --plugin-dir loading. (#2330)
permission decision context forwarding — Permission handlers can now attach a decisionContext so the runtime can attribute whether a decision came from a person, a host policy, or an automated recommendation. This is additive for TypeScript, C#, Go, Python, and Java. Rust clients that construct PermissionResult::Decision directly must migrate from the tuple variant to the new struct variant. (#2294)
ClientMode::Empty now defaults to no built-in skills — When creating a session with ClientMode::Empty, built-in skills are now disabled by default. To opt specific skills in, supply an explicit includedBuiltinSkills allowlist. Custom skills via enableSkills and skillDirectories are unaffected. (#2410)
Java in-process CLI runtime for Linux, Windows, and macOS — The Java SDK now ships a bundled native CLI runtime for Linux x64, Linux ARM64, Windows x64, Windows ARM64, and Apple Silicon macOS. Applications on these platforms no longer need a separately installed Copilot CLI binary. (#2301, #2393, #2402, #2421, #2427)
