v1.9.0 - Esperanto 2.22 & New Audio Providers

on GitHub

✨ Highlights

• Upgraded to Esperanto 2.22.0, unlocking new providers and inheriting several upstream fixes.
• New audio providers:
  • Mistral Voxtral — speech-to-text and text-to-speech (reuses your Mistral credential)
  • Deepgram — text-to-speech (Aura voices) — new provider
  • xAI — text-to-speech
  • Completed the matrix: Google STT/TTS, Vertex TTS, ElevenLabs STT (Scribe)
• Per-credential Ollama num_ctx override — configure the context window for Ollama models in Settings → API Keys (translated across all 13 locales).
• Better speech-to-text connection tests — they now transcribe a real speech clip instead of silence, so a passing test shows actual text.

⚠️ Upgrade Notes (behavior changes inherited from Esperanto)

• Ollama default context window (num_ctx) is now 8192 (was 128000) to avoid out-of-memory errors on consumer GPUs. If you ingest large documents with Ollama, set a higher num_ctx on the Ollama credential.
• Google embedding default model is now gemini-embedding-001 — the previous default, text-embedding-004, was removed from Google's API. If you used Google embeddings with the old default, re-create the model and re-embed your content (the embedding dimensions changed).

🛠️ Inherited Esperanto fixes

• OpenRouter LLM & embedding requests now send a proper JSON body.
• Clear errors (instead of an opaque TypeError) when OpenAI-compatible endpoints return null embeddings.
• Streaming tool calls return proper objects across Anthropic, Google, Vertex, and Ollama.
• base_url trailing slashes normalized (fixes double-slash 301s for Ollama / self-hosted).
• Ollama "thinking" models (e.g. Qwen) merge reasoning content correctly.
• Model discovery honors a custom base_url (LiteLLM/vLLM/proxies).

➕ Also in this release

• CORS_ORIGINS env var to configure allowed API origins (#585, #597, #730)
• OPEN_NOTEBOOK_MIN_CHUNK_SIZE env var to filter degenerate tiny chunks
• Fixed URL-source embedding crash on single-character HTML fragments (#764)
• README Provider Support Matrix synced with actual capabilities
