Pi 1.2.0 released
A feature release adding per-key OpenRouter model lists, configuration schemas for editor validation, and clipboard support over remote sessions.
What changed in 1.2.0
- OpenRouter keys now show only their available models with context size, output limits, and pricing information.
- Configuration schemas published for settings, models, keybindings, and themes to enable editor validation and autocompletion.
- Clipboard copies can reach remote clients via OSC 52 when Pi cannot detect the remote session.
- Codemode tool rows display input constraints and elapsed/total time; tool declarations show constraint tags.
- Multiple fixes including Mistral stream timeouts, MCP resource handling, symlinked project files, and Windows file locking issues.
Check before you update
- Theme schema location changed; update theme $schema references and use vars for reusable colors.
- before_agent_start event is now a union type with messageType: handlers must check messageType === "user" to act only on user prompts.
- Session counts as busy during run startup including before_agent_start; pi.sendMessage() now queues into starting runs, and pi.sendUserMessage() requires deliverAs parameter.
