Full Release Notes

## What's New

### Podcast Model Registry Integration & Credential Passthrough

Episode and speaker profiles now use the model registry instead of loose provider/model strings. This enables automatic credential passthrough to podcast-creator and brings podcasts in line with the rest of the system.

- Episode profiles use `outline_llm` / `transcript_llm` (model registry references) instead of provider/model strings
- Speaker profiles use `voice_model` (model registry reference) instead of tts_provider/tts_model strings
- Credentials are automatically resolved and passed to podcast-creator
- New `language` field on episode profiles (BCP 47 locale codes like pt-BR, en-US)
- Per-speaker voice model override support
- Data migration auto-converts legacy profiles on startup (idempotent)
- New `GET /api/languages` endpoint
- Profile forms use ModelSelector component instead of manual provider/model dropdowns
- "Templates" tab renamed to "Profiles"
- "Setup required" badge on profiles missing model configuration
- i18n updated across all 8 locales
- Added `pycountry` and `babel` dependencies

Closes #486, closes #552

### Chat: Remove 50-source cap

Notebook chat context no longer has a hard limit of 50 sources. All sources in a notebook are now available for context. (#628)

### Docker: Pin SurrealDB version

Pin SurrealDB to a specific version in Docker Compose to prevent breaking changes from upstream updates. Also fixes single-container documentation. (#629)

### UI: Fix CJK text orientation

Correct text orientation for CJK (Chinese, Japanese, Korean) characters in the collapsible column component. (#619)

### Other

- docs: add missing `SURREAL_NAMESPACE` and `SURREAL_DATABASE` env vars
- chore(deps-dev): bump tar from 7.5.7 to 7.5.9 in frontend

### Migration

Existing podcast profiles are automatically migrated on first startup. If your profiles used providers with configured credentials, the migration is seamless. Profiles that can't be auto-migrated will show a "Setup required" badge in the UI.
