Will the open-source server get Pi player image upgrades?

Yes. If the open-source (local) server is connected to the Internet, it checks pisignage.com for a new Raspberry Pi player version when it starts and every day at midnight (server time). When a new version is out, the server downloads the player images into its data/releases folder.

Players are not upgraded automatically. To upgrade a player:

1. Open Players on your server.
2. Next to the player's version, click the orange arrow button. It shows only when a newer version is available.
3. Click OK in Software Update. The player downloads the new version from your server.

The player must be online. A server without Internet access does not get new versions.
