Release Notes

2026-10-19 - Add --disable-client-telemetry flag to turn off client telemetry uploads from the CLI - Add --trust-folder for one-off prompt-mode sessions started with -p or piped stdin - Install verified Skills and plugins from GitHub install links via copilot plugin install "ghapp://air/install?..." - Open /share without arguments to view a full-screen action menu for sharing the current session - Sandbox host-rule traffic now honors HTTPSPROXY and HTTPPROXY when no sandbox proxy is configured - Voice dictation no longer inserts language markers like <en-US> into transcript text - Managed plugins update activation in existing sessions when managed policy changes - Sessions no longer stall for minutes when an MCP server hangs while loading tools. - Gemini tool calls no longer fail when array parameters define enum values - Gemini chats no longer fail after earlier tool results contain no readable content. - Sandboxed shell commands now explain credential-proxy certificate trust failures and can offer an approved rerun outside the sandbox. - Keep saved /diff review comments when reopening an unchanged diff in the same session, with an explicit discard action. - Plugin enable, disable, update, and uninstall actions now route reliably after plugin inventory refreshes. - Reasoning-only max-token responses no longer loop indefinitely and now end with a clear error when no progress is made - Show a clear warning and keep the active model display in sync when a saved model is automatically replaced on resume. - Sandboxed commands on Linux start more reliably without intermittent loopback setup failures - Back from MCP resource details stays on the list during live metadata refreshes - Native chats can start and finish while optional managed plugin downloads continue in the background. - Double Ctrl+C exits immediately even when the CLI UI is busy - Catalog search reports proxy authentication requirements for CONNECT proxy challenges - HydraFusion keeps a pass expanded while its review runs, passes that were not kept stay expandable until you switch sessions or resume, and passes from an aborted turn say whether they were kept - Managed account policy and bypass-mode warnings stay accurate after switching accounts, even when a policy cache miss happens. - Avoid false context exhaustion and rollover refusal when tool definitions are deferred - Custom agents that declare the documented search, web or todo tool aliases, or name github-mcp-server/websearch, now receive the matching tools - CLI help and version flags exit reliably after printing their output - Enterprise-managed ask permissions in Assisted mode now allow safe actions without unnecessary confirmation prompts. - Keep your selected Microsoft Entra account pinned during sign-in and token renewal - Up from sessions sidebar header actions wraps to the last visible session - Plan, autopilot, and shell mode badges stay visible while startup components load and the agent works. The badge replaces the mode suffix that used to trail the activity text (Working - plan), and the startup Loading: row now truncates its diagnostics to keep the status row on one line - Sandboxed commands can write package and build caches when developer tool access is enabled. - Windows CLI Git commands now recover from thread-access-denied startup failures. - A skill allowed-tools rule keeps commas inside its arguments instead of being split apart. Where a list's structure is ambiguous, its unscoped rules now prompt instead of being granted. - MCP resource dashboard stays interactive while inventory adapters refresh - Retry image-bearing Responses requests with smaller payload limits when providers reject oversized bodies - Complete usage reporting no longer shows partial status or phantom unattributed spend after resume when billing data is complete. - Assisted permissions send nested PowerShell and bash -c commands that only expand plain-data environment variables, single-quoted PowerShell, and PowerShell variable and alias statements to the permission judge instead of requiring unnecessary manual approval - Path-specific instruction files in the repository root .github/instructions are now applied automatically when the agent reads or edits a matching file - Start git, shell commands, and MCP servers on Windows when process snapshot thread enumeration fails - Use the unified Sessions browser by default for /sessions, /session, and /resume. - Session browsing now caps account discovery at 500 records and respects Retry-After hints for automatic refresh timing. - Prompt to update the sandbox proxy certificate authority when masked hosts change - Show a clear notice when administrator-managed settings override your selected model - Enable semantic code search by default for online sessions. - Improve /login for Microsoft Entra by letting you choose a cached account or explicitly sign in with a different account - Sandboxed git on github.com can use your configured GITHUBTOKEN from credentials.envVars - /sandbox can keep sandboxing enabled for the current session without enabling it globally - Trusted repository plugins install and update automatically before chat runs. - Rename the built-in browser plugin to browser-use and keep existing browser plugin preferences working after upgrade - Sandbox allows local network access by default so commands can reach localhost and private-network services.
