Copilot Chat v0.33.2025102201: Sessions & Anthropic Support

TL;DR

• CCA now uses sessions API for better state management
• Extended thinking support added for BYOK Anthropic models
• Improved pending changes handling and prompt resolution by model

New

• Extended thinking for Anthropic BYOK — Bring-your-own-key Anthropic models now support extended thinking for deeper reasoning.
• Prompt file parser — New promptFileParser for better prompt handling and resolution.
• Model-based prompt resolution — Prompts now resolve by model instead of modelFamilies, giving finer control over model-specific behavior.
• Custom terminal confirmation tool — Terminal operations now use a dedicated confirmation tool for safer execution.

Fixed

• Pending changes handling — CCA now properly handles pending changes in your workspace.
• Agent sessions sorting — Sessions now sort correctly in the UI.
• Markdown link in Run Command tool — Fixed broken link formatting in the Run Command tool.
• Plan implementation prevention — Plans no longer attempt to auto-implement, giving you more control.

Changed

• CCA switched to sessions API — Internal refactor for better session management and state handling.
• Agent naming — vscode-agent renamed to agent for consistency.
• Editor change detection — Trigger-on-active-editor-change setting now uses last-edit-time-based logic.
