New Features - Added a built-in amazon-bedrock model provider with configurable AWS profile support (18744). - Added /mcp verbose for full MCP server diagnostics, resources, and resource templates while keeping plain /mcp fast (18610). - Made plugin MCP loading accept both mcpServers and top-level server maps in .mcp.json (18780). - Improved realtime handoffs so background agents receive transcript deltas and can explicitly stay silent when appropriate (18597, 18761, 18635). - Added host-specific remotesandboxconfig requirements for remote environments (18763). - Refreshed bundled model metadata, including the current gpt-5.4 default (18586, 18388, 18719). Bug Fixes - Fixed /copy after rollback so it copies the latest visible assistant response, not a pre-rollback response (18739). - Queued normal follow-up text submitted while a manual shell command is running, preventing stuck Working states (18820). - Fixed Unicode/dead-key input in VS Code WSL terminals by disabling the enhanced keyboard mode there (18741). - Prevented stale proxy environment variables from being restored from shell snapshots (17271). - Made codex exec inherit root-level shared flags such as sandbox and model options (18630). - Removed leaked review prompts from TUI transcripts (18659). Documentation - Added and tightened the Code Review skill instructions used by Codex-driven reviews (18746, 18818). - Documented intentional await-across-lock cases and enabled Clippy linting for them (18423, 18698). - Updated app-server protocol docs for threadless MCP resource reads and namespaced dynamic tools (18292, 18413). Chores - Fixed high-severity dependency alerts by pinning patched JS and Rust dependencies (18167). - Reduced Rust dev build debug-info overhead while preserving useful backtraces (18844). - Refreshed generated Python app-server SDK types from the current schema (18862).
