# Pearl firmware 4.24.1 — all Pearl systems

*Applies to: Pearl-2, Pearl Mini, Pearl Nexus, Pearl Nano.*

- **REST API developer-access mode** directly within the Pearl web interface, enabling users to execute, copy, and paste API commands.
- **Delcom USB buttons** can start, stop, pause, and resume Panopto, Kaltura, and Opencast events. *Correction: pausing and resuming Kaltura events, including with Delcom buttons, was added in firmware 4.24.6; it was not possible in 4.24.1.*
- **EU-hosted Epiphan Edge option** for European customers, giving faster data transfer and lower processing latency.
- **Selectable management and control interface** — Pearl-2, Pearl Mini, and Pearl Nexus.
- **Pearl-2:** support for embedding audio into secondary Panopto channels for files stored locally.

Epiphan Cloud EU servers only support Pearl devices on firmware version 4.24.1 or newer.
