## Groups
### New Features
- Set up API keys for additional providers in the Manage Group page to
enable additional capabilities for assistants and other PingPong
features.
- Set up a Google Gemini API key for video processing and question
generation, and an Eleven Labs API key for text-to-speech for video
narration in Lecture Video mode.
- Cloning a Lecture Video mode assistant requires that both groups share
the same AI Provider API key as previously, **and** the same Additional
Providers API keys.
- The Manage Group page shows saved Additional Providers credentials in
redacted form for Institutional Admins and indicates whether Lecture
Videos are ready to use or still need setup.
### Notes
- In a future update, Lecture Video mode in the Assistant editor will be
gated upon the completion of the Additional Providers section for
Lecture Videos in the Manage Group page.

## Internal
### Updates & Improvements
- Centralized API key redaction into a shared helper to ensure
consistent masking across all endpoints.
- API key responses now return `redacted_api_key` instead of `api_key`.
The field was renamed to make it explicit that the value is masked, not
the raw key.
- Credential validation calls to external providers are subject to a
10-second timeout.
- Added `elevenlabs` and `google-genai` as new backend dependencies.
