AI Summary

Upgraded to Esperanto 2.22.0, adding new audio providers like Mistral Voxtral and Deepgram, while adjusting default Ollama context windows and Google embedding models to prevent errors and improve compatibility.

Key Highlights

  • Upgraded to Esperanto 2.22.0
  • New audio providers: Mistral Voxtral, Deepgram, and xAI
  • Per-credential Ollama `num_ctx` override
  • Improved speech-to-text connection tests

Breaking Changes

  • Ollama default context window changed from 128000 to 8192
  • Google embedding default model changed to `gemini-embedding-001` (previous model removed)

New Features

  • New audio providers (Mistral Voxtral, Deepgram, xAI)
  • Per-credential Ollama `num_ctx` override
  • Better speech-to-text connection tests
  • Environment variable support for tuning (batch size, CORS, chunk size)
  • Inherited Esperanto fixes for OpenRouter and streaming
  • Model discovery honors a custom `base_url`

Full Release Notes

## ✨ 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

- `OPEN_NOTEBOOK_EMBEDDING_BATCH_SIZE` env var to tune embedding batch size (#735)
- `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
