v0.preview.69

v0.preview.69 - 2026-08-02

Added

• Shift+Enter and Ctrl+Enter insert a newline in the composer on terminals with kitty keyboard protocol support (kitty, ghostty, WezTerm, iTerm2 3.5+, Alacritty 0.13+)

Changed

• Diff View V2 across all diff surfaces — chat Edit/Write details, the /diff pager, the approval Tab preview, and the theme dialog: numbered line gutter, full-width added/removed background bands, and +N -M change counts inline in headers

Fixed

• Normalize MCP tool schemas to the portable provider subset at ingestion, so servers using advanced JSON Schema keywords (exclusiveMinimum, $ref, oneOf, …) no longer get requests rejected by strict providers such as Gemini
• Merge system prompt fragments into a single leading system message for unrecognized OpenAI-compatible models, fixing strict local chat templates that error on multiple system messages
• Spinner token count now shows only tokens generated this turn (it previously re-added the full context every generation, inflating wildly), with a ↑/↓ request/stream phase arrow
• Gemini quota errors that mention token limits are classified as quota, not context overflow, so they no longer trigger futile compaction
