[Unreleased]

[1.7.2] - 2026-02-16

Added

• Error classification utility that maps LLM provider errors to user-friendly messages (#506)
• Global exception handlers in FastAPI for all custom exception types with proper HTTP status codes
• getApiErrorMessage() frontend helper that falls back to backend messages when no i18n mapping exists

Fixed

• LLM errors (invalid API key, wrong model, rate limits) now show descriptive messages instead of "An unexpected error occurred"
• SSE streaming error events in source chat and ask hooks were swallowed by inner JSON parse catch blocks
• Transformation execution errors were caught and re-wrapped as generic 500s instead of using proper status codes

Changed

• ValueError replaced with ConfigurationError in model provisioning for proper error classification
• ConfigurationError added to command retry stop_on lists to avoid retrying permanent config failures

Added

• Credential-Based Provider Management (#477)

  • New Settings → API Keys page for managing AI provider credentials via the UI
  • Support for 14 providers: OpenAI, Anthropic, Google, Groq, Mistral, DeepSeek, xAI, OpenRouter, Voyage AI, ElevenLabs, Ollama, Azure OpenAI, OpenAI-Compatible, and Vertex AI
  • Secure storage of API keys in SurrealDB with field-level encryption (Fernet AES-128-CBC + HMAC-SHA256)
  • One-click connection testing, model discovery, and model registration per credential
  • Migration tool to import existing environment variable keys into the credential system
  • Azure OpenAI support with service-specific endpoints (LLM, Embedding, STT, TTS)

  • Default password "open-notebook-change-me" for out-of-box experience (change in production!)
  • URL validation for SSRF protection - blocks private IPs and localhost (except for Ollama which runs locally)
  • Security warnings logged when using default credentials

• HTML clipboard detection for text sources (#426)

  • When pasting content, automatically detects HTML format (e.g., from Word, web pages)
  • Shows info message when HTML is detected, informing user it will be converted to Markdown

  • Cross-references between docker-compose examples and documentation
  • .env.example template with all configuration options

Fixed

• Azure form race condition: all configuration now saved in single atomic request
