When you want to develop different features in the same project simultaneously without interrupting progress by frequently switching branches, dedicated tools are now available in trusted local projects. Once the worktree feature is enabled, the AI can directly create and list managed Git worktrees (parallel copies of the same project managed by Git).
When tracking multiple tasks simultaneously in the agent command center and looking to keep the most critical items prominent, you can now press the p key on your keyboard to pin them quickly. As long as the server supports this capability, pinned tasks are consolidated into a shared Pinned group, making it easy to review their progress at any time.
When browsing long conversations in the terminal UI, extracting specific code snippets or key responses is now much smoother. You can enter /copy to select and copy conversation blocks, or press Ctrl+Insert to copy text currently highlighted by the mouse. If the terminal UI scrolls too fast or too slow, you can also add tui.mouse_scroll_speed in the settings to adjust the mouse wheel scroll speed.
When the AI displays confirmation questions or warning messages in the terminal with reference URLs, you no longer need to manually highlight and copy them. Whether a URL appears in a confirmation header, question list, warning banner, verification prompt, or an MCP (Model Context Protocol, a protocol that connects AI to external tools) prompt, you can click to open it directly. Even if a URL is long and wrapped to the next line by the terminal, the link still opens completely without breaking in two.
If you connect custom model providers compatible with the Responses API, you can now enable more advanced capabilities for them. You can configure live web access directly for these custom models so they can retrieve the latest web information. You can also configure remote compaction so that conversation summaries are processed remotely.
When writing automation scripts or handling numerous tools in Code Mode, the development experience is further enhanced. New JavaScript helper utilities now stream results back immediately as multiple asynchronous operations (Promise instances) complete individually, without waiting for every task to finish. Furthermore, in Code Mode, you can actively enable ranked tool search so the system recommends the most relevant tools by relevance.
When starting a new terminal conversation, the system now prioritizes server-configured defaults for models and reasoning summaries. Whereas creating a new conversation previously could ignore default server settings, the system now adheres fully to these defaults. If you manually pass specific parameters at launch, the system also prioritizes and retains your explicit override values instead of overwriting them with defaults.
When patching code in Windows environments, you no longer need to manually specify settings to preserve original line endings. Previously, updating files with apply_patch could alter existing CRLF line endings (the standard Windows line-ending format) unless an extra option was enabled; apply_patch now automatically preserves the file's original line endings. This issue is resolved, preventing unintended diffs across the entire file when committing changes to version control.
When using the security sandbox to isolate execution environments on Linux, the system fixed several security constraints related to startup and file access. The sandbox previously could fail to start when multiple denied files were configured, but this startup process is now fixed. Sandboxes now reject writable executables used to construct the sandbox. The ripgrep configuration was also corrected to ensure search settings do not weaken deny-glob file mask protections.
If you run commands or use sandboxed environments on Windows 10, previously encountered missing path and permission errors are now resolved. Standard drive letter file access (such as common C: and D: drives) is restored, preventing errors when reading or writing existing files. Permissions for temporary directories inside the Windows sandbox are also aligned with environments of subprocesses (child processes started by the main program), preventing programs from hanging due to permission mismatches during execution.
When using Codex, if a sent request or real-time connection fails, you may need to wait for a while before retrying. Retryable failures for Responses (the interface for sending model requests) now follow the server's Retry-After recommendation. This header tells the client how long to wait before trying again. Retryable failures for WebSocket connections (which maintain two-way, real-time communication) also follow this rule by waiting for the suggested duration before retrying.
When installing or updating the system on Windows, installer scripts and version download mechanisms now offer higher security and compatibility. Windows releases now include a signed PowerShell installer. When PowerShell 7 module paths exist in the environment, archive checksum verification failures that previously occurred when installing through Windows PowerShell are now fixed. For download management, the system now prevents older or preview versions from accidentally overwriting newer stable download targets and installation aliases.
