Cortex Code Desktop v1.21.4 release notes¶

v1.21.4 is a polish and reliability release on top of v1.21.3. It brings the Windows installer to parity with macOS, lets you add highlighted conversation text to chat, adds a way to cancel a pending steering message, keeps dbt runs focused on their output, and fixes a bug that could fail a fresh Gemini session.

What’s new¶

• Add highlighted conversation text to chat: Select any text in a conversation and use the Add to Chat pill or press ⌘L / Ctrl+L to attach it to your next message as a removable chip, the same quick-attach flow the editor and terminal already offer. Very long selections are truncated with a note.

• Cancel a pending steering message: An armed steering message now has a cancel control, so you can remove it without stopping the active turn. Keyboard focus is preserved after the message is removed.

• Windows installer matches macOS: The Windows installer no longer shows a License Agreement click-through page, bringing it to parity with the macOS installer. The license file still ships in the installed application directory.

• dbt runs stay focused on Output: After you Run or Build from the Project Action Bar, you remain on the Current Project Output panel instead of being switched to Lineage. When a package-loading command is disabled, the tooltip now directs you to Run configuration, where the external access integration picker lives.

Reliability and fixes¶

• Fixed: fresh Gemini sessions could fail with a 400 error: Desktop now captures the Gemini thought signature from tool-use events, so a signed first-turn tool call is replayed correctly on the next turn instead of being rejected.
