# Changelog

All notable changes to the Indie language project.

<Update label="15 Jun '26" description="v5.16.0">
  This release turns your AI assistant into a hands-on co-pilot: through the MCP server it can now build and manage your Indie scripts and your alerts end-to-end, signing in with your TakeProfit account — no extra credentials to set up.

  #### Added

  * **Manage Indie scripts from AI.** New MCP tools let the AI create, read, update, and run your Indie scripts directly — so you can build and edit indicators from a chat instead of switching to the IDE.
  * **Manage alerts from AI.** New MCP tools give the AI full control over alerts — create, read, update, and delete them, turn them on or off, preview before saving, inspect their schema, and review trigger history — all from a conversation.
  * **Richer alert messages.** An alert message can now reference *any* plot of an indicator used in the alert, not just the series directly involved in the condition — so notifications can include more of what the indicator calculates.
  * **Simpler MCP sign-in.** The MCP server now authenticates with your existing TakeProfit platform account — no separate API keys or credentials required.
</Update>

<Update label="07 May '26" description="v5.15.0">
  #### Added

  * Light theme support in the IDE widget.
  * Indicator recovery: if a calculation error occurs, the indicator now recovers gracefully and shows available history with a refresh button, instead of crashing.

</Update>

<Update label="17 Apr '26" description="v5.14.0">
  #### Added

    * `TakeProfit_SearchMarketplaceIndicators`: search community indicators in the Marketplace — LLM can now recommend indicators by description.
  * MCP OAuth authentication through TakeProfit platform account.
  * MCP back-to-back endpoint enabling MCP tools to be used from the AI Chat without additional auth setup.
