0.0.350 - 2025-10-23

To conserve context window space, we've limited the list of tools available to the default GitHub MCP server. In our tests, the model will use the GitHub CLI, gh (if installed) in lieu of missing MCP tools. We added an --enable-all-github-mcp-tools if you wish to turn on all available tools. Default available tools are: - Code & Repo navigation - get_file_contents - search_code - search_repositories - list_branches - list_commits - get_commit - Issue Management - get_issue - list_issues - get_issue_comments - search_issues - PR Management - pull_request_read - list_pull_requests - search_pull_requests - Workflow Info - list_workflows - list_workflow_runs - get_workflow_run - get_job_logs - get_workflow_run_logs - Misc search - user_search

Added new model:
Run slash model to equip
Haiku 4.5.

Added a flag to augment MCP server configuration to temporarily add or override server configuration per session: --additional-mcp-config (fixes #288)
- You can pass MCP server configuration in two ways:
  - Inline JSON: copilot --additional-mcp-config '{"mcpServers": {"my-tool": {...}}}'
  - From a file (prefix with @): copilot --additional-mcp-config @/path/to/config.json
- You can also pass the flag multiple times (later values override earlier ones): copilot --additional-mcp-config @base.json --additional-mcp-config @overrides.json

0.0.342 - 2025-10-15

Overhauled our session logging format:
- Introduced a new session logging format that decouples how we store sessions from how we display them in the timeline. The new format is cleaner, more concise, and scalable, and will allow us to more easily implement new features down the line.
- New sessions are stored in ~/.copilot/session-state
- Legacy sessions are stored in ~/.copilot/history-session-state -- these will be migrated to the new format & location as you resume them from copilot --resume
Enabled the Kitty protocol by default. Multi-line input is now supported via Shift+Ctrl on terminal that support the Kitty protocol. Multi-line input is also supported in VSCode and its forks by running the /terminal-setup command (fixes #14)
Enabled non-interactive GHE logins by respecting the GH_HOST environment variable for PAT and gh authentication modes (fixes #296)
Improved debug log collection convenience by adding a persistent log_level option in ~/.copilot/config. Possible values: ["none", "error", "warning", "info", "debug", "all", "default"]
Added debug logging when calls to /model result in Copilot API errors. This should help us diagnose some policy/model access edge cases like #268 and #116

Fixed an issue where consecutive orphaned tool calls led to a "Each tool_use block must have a corresponding tool_result block in the next message" message (fixes #102)
Added a prompt to approve new paths in -p mode. Also added --allow-all-paths argument that approves access to all paths.
Changed parsing of environment variables in MCP server configuration to treat the value of the env section as literal values (fixes #26). Customers who have configured MCP Servers for use with the CLI will need to make a slight modification to their ~/.copilot/mcp-config.json. For any servers they have added with an env section, they will need to go add a $ to the start of the "value" pair of the key value pair of each entry in the env-block, so to have the values treated as references to environment variables.

For example: Before:
```
{
    "env": {
        "GITHUB_ACCESS_TOKEN": "GITHUB_TOKEN"
    }
}
```
Before this change, the CLI would read the value of GITHUB_TOKEN from the environment of the CLI and set the environment variable named GITHUB_ACCESS_TOKEN in the MCP process to that value. With this change, GITHUB_ACCESS_TOKEN would now be set to the literal value GITHUB_TOKEN. To get the old behavior, change to this:
```
{
    "env": {
        "GITHUB_ACCESS_TOKEN": "${GITHUB_TOKEN}"
    }
}
```

0.0.339 - 2025-10-10

Improved argument input to MCP servers in /mcp add -- previously, users had to use comma-separated syntax to specify arguments. Now, the "Command" field allows users to input the full command to start the server as if they were running it in a shell
Fixed a bug when using the Kitty protocol that led to text containing u to not paste correctly. Kitty protocol support is still behind the COPILOT_KITTY environment variable. (Fixes #259)
Fixed a bug when using the Kitty protocol that led to the process hanging in VSCode terminal on Windows. Kitty protocol support is still behind the COPILOT_KITTY environment variable. (Fixes #257)
Improved the error handling in the /model picker when no models are available (fixes #229)

0.0.338 - 2025-10-09

Moved Kitty protocol support behind the COPILOT_KITTY environment variable due to observed regressions (#257, #259)
Fixed a wrapping issue in multi-line prompts with empty lines

0.0.337 - 2025-10-08

Added validation for MCP server names (fixes #110)
Added support for Ctrl+B and Ctrl+F for moving cursor back and forward (fixes #214)
Added support for multi-line input for terminals that support the Kitty protocol (partially fixes #14 -- broader terminal support coming soon!)
Updated the OAuth login UI to begin polling as soon as the device code is generated (this will more solidly fix SSH edge-cases as described in #89)

0.0.336 - 2025-10-07

Enabled proxy support via HTTPS_PROXY/HTTP_PROXY environment variables regardless of Node version (Fixes #41)
Significantly reduced token consumption, round trips per problem, and time to result. We'll share more specific data in our weekly changelog on Friday!
Improved file write performances (especially on Windows) by not relying on the shell to fetch the current working directory
Fixed a bug where /clear did not properly reset the context truncation tracking state
Hid the "Welcome to GitHub Copilot CLI" welcome message on session resumption and /clear for a cleaner look
Improved the alignment of tables where the scrollbar is present
Improved the output of --help by making it more concise
Added a prompt for users who launch with --screen-reader to persistently save this preference
Potentially improved flickering in some cases; we're still working on this!

0.0.335 - 2025-10-06

Improved visibility into file edits by showing file diffs in the timeline by default, without the need to Ctrl+R
Improved slash command input by showing argument hints in the input box
Improved the display of the interface in windows less than 80 columns wide
Reduced the number of colors and improved the spacing of Markdown rendering
Added a warning when attempting to use proxy support in an environment where it won't work (Node <24, required environment variables not set) (A more permanent fix for #41 is coming ~tomorrow)
Updated the context truncation message's color from an error color to a warning color
Fixed a bug where copilot logs might not have been properly created on Windows
Fixed a bug where Powershell users with custom profiles might have had issues running commands (Fixes #196)
Fixed a bug where prompts were truncated after pasting and other edge cases (Fixes #208, #218)
Fixed a bug where users would see a login prompt on startup despite being logged in (fixes #202)
Fixed a bug where some SSH users in certain environments were unable to get the OAuth login link and had their processes hang trying to open a browser (fixes #89)

0.0.334 - 2025-10-03

Improved the experience of pasting large content: when pasting more than 10 lines, it's displayed as a compact token like [Paste #1 - 15 lines] instead of flooding the terminal.
Added a warning when conversation context approaches ≤20% remaining of the model's limit that truncation will soon occur. At this point, we recommend you begin a new session (improves #29)
Removed the on-exit usage stats from the persisted session history
Added the current version to startup logs to aid in bug reporting
Removed cycling through TAB autocomplete items if an argument is present. This prevents running /cwd /path/to/whatever, hitting TAB, then seeing /clear autocomplete

0.0.333 - 2025-10-02

Added image support! @-mention files to add them as input to the model.
Improved proxy support for users on Node.JS v24+. See this comment for more details (Fixes #41)
Added support for directly executing shell commands and bypassing the model by prepending input with ! (fixes #186, #12)
Added /usage slash command to provide stats about Premium request usage, session time, code changes, and per-model token use. This information is also printed at the conclusion of a session (Fixes #27, #121)
Improved --screen-reader mode by replacing icons in the timeline with informative labels
Added a --continue flag to resume the most recently closed session
Updated the /clear command to properly clear old timeline entries/session information (Fixes #170)

0.0.332 - 2025-10-01

Switched to using per-subscription Copilot API endpoints in accordance with GitHub's docs (fixes #76)
Fixed a bug where /user [list | show | switch] did not include users signed in from all authentication modes (fixes #58)
Fixed a bug where switching to another user with /user switch did not take effect in the GitHub MCP server
Improved the screenreader experience by disabling the scrollbar in the @ file picker, the --resume session picker, and the / command picker
Improved the polish of the scrollbar container (increased the width, reduced the opacity of the gutter)
Minor visual improvements to the input area (moved the current model indicator to the right so it's not cramped with the CWD, improved the positioning of the file picker's "indexing" indicator, improved hint formatting in completion menus)
Improved Markdown legibility by excluding # prefixes in headings
Improved how we extract paths from shell commands for permission handling (might fix #159, #67)

0.0.331 - 2025-10-01

Improved the information density of file read/edit timeline events
Fixed an inaccuracy in the --banner help text; it previously implied that it would persistently change the configuration to always show the startup banner
Improved the /models list to ensure that a user only sees models they have access to use -- previously, if a user tries to use a model they do not have access to (because of their Copilot plan, their geographic region, etc), they received a model_not_supported error. This should prevent that by not even showing such models as options in the list (Fixes #112, #85, #40)
Fixed a bug where pressing down arrow in a multi-line prompt would wrap around to the first line (This is on the way to implementing #14)
Added a scrollbar to the @ file mentioning picker and increased the size of the active buffer to 10 items
Improved the experience of writing prompts while the agent is running -- up/down arrows will now correctly navigate between options in the @ and / menus

0.0.330 - 2025-09-29

Changed the default model back to Sonnet 4 since Sonnet 4.5 hasn't rolled out to all users yet. Sonnet 4.5 is still available from the /model slash command

0.0.329 - 2025-09-29

Added support for Claude Sonnet 4.5 and made it the default model
Added /model slash command to easily change the model (fixes #10)
- /model will open a picker to change the model
- /model <model> will set the model to the parameter provided
Added display of currently selected model above the input text box (Addresses feedback in #120, #108, )
Improved error messages when users provide incorrect command-line arguments. (Addresses feedback of the discoverability of non-interactive mode from #96)
Changed the behavior of Ctrl+r to expand only recent timeline items. After running Ctrl+r, you can use Ctrl+e to expand all
Improved word motion logic to better detect newlines: using word motion keys will now correctly move to the first word on a line
Improved the handling of multi-line inputs in the input box: the input text box is scrollable, limited to 10 lines. Long prompts won't take up the whole screen anymore! (This is on the way to implementing #14)
Removed the left and right borders from the input box. This makes it easier to copy text out of it!
Added glob matching to shell rules. When using --allow-tool and --deny-tool, you can now specify things like shell(npm run test:*) to match any shell commands beginning with npm run test
Improved the copilot --resume interface with relative time display, session message count, (Fixes #97)

0.0.328 - 2025-09-26

Improved error message received when Copilot CLI is blocked by organization policy (fixes #18 )
Improved the error message received when using a PAT that is missing the "Copilot Requests" permission (fixes #46 )
Improved the output of /user list to make it clearer which is the current user
Improved PowerShell parsing of ForEach-Object and detection of command name expressions (e.g.,& $someCommand)
