ScreenlyOS 26.10.0: Players no longer trust certificates from emSign ECC Root CA - G3

Mon, 26 Oct 2026 00:00:00 +0000

From ScreenlyOS 26.10.0, players no longer accept certificates issued under emSign ECC Root CA - G3. On October 20, 2026, keys belonging to certificate authorities under that root were found to be compromised (Mozilla bug 2083449). Players stop trusting it, for the web pages they show and for their own connections.

If this affects you: a web page on your screens whose certificate comes from emSign ECC Root CA - G3 stops loading on players running 26.10.0. Ask whoever runs the site to move to a certificate from another authority.

ScreenlyOS 26.10.0: The Device Information page shows a player's details on the display

Mon, 26 Oct 2026 00:00:00 +0000

Support asks for a player’s serial number and MAC address, and you’re standing in front of it with a keyboard. Press F8 and the Device Information page now lists the details on the display:

model and serial number
Ethernet and Wi-Fi IP and MAC addresses
whether secure boot and disk encryption are on

Before, the page showed only a QR code, so reading anything off it meant getting a phone out. The QR code is still there, next to the list, for when you’d rather send the details to your phone than copy them down.

ScreenlyOS 26.10.0: Apps on x86 players with a TPM always get their saved keys and passwords

Mon, 26 Oct 2026 00:00:00 +0000

On x86 players with a TPM, an app that played after any web page had loaded lost the API keys and passwords saved in its settings, so it couldn’t fetch its data.

From ScreenlyOS 26.10.0, apps on these players get them every time, whatever played before them.

ScreenlyOS 26.10.0: A screen keeps showing its content while a single new item loads

Mon, 26 Oct 2026 00:00:00 +0000

Switching a screen to a single item that couldn’t load yet, such as an app still downloading its files or a web page that failed to load, turned the screen black while the player tried again.

The screen now keeps showing what was there, the previous content or the same item if it was already playing, until the new item loads. Screens with more than 1 item to show already worked this way.

ScreenlyOS 26.10.0: Audio plays through the right port on Raspberry Pi, and other fixes

Mon, 26 Oct 2026 00:00:00 +0000

Fixes

On a Raspberry Pi, audio set to HDMI could play through the HDMI port with no display on it, and audio set to the headphone jack came out of the second HDMI port instead. HDMI audio now plays through the port the display is connected to, and headphone jack audio plays from the jack. On a Raspberry Pi 5, which has no headphone jack, it plays through HDMI.
Pressing F3 for network diagnostics showed the results of the checks from when the player started. F3 now runs the checks each time.
The time server check, on the diagnostics screen and in support reports, always tested ntp.ubuntu.com. It now tests the time server the player is set to use.
Pressing F3 or F8 while help or a setup screen was open stopped R from working until the player restarted. R now works after either key.

Improvements

Optimizations for video playback on LED screens.
A screen whose connection to Screenly drops after it’s been up for a while reconnects right away, so commands like a reboot or a screenshot reach it sooner.
The setup file on a USB drive is now called screenlyos-config.yaml. Drives that still have network.yaml keep working.
Dependencies and system libraries updated.
