The popular Umbrel OS, which is also THE software for many Bitcoin nodes, has been updated to version 1.4. The update can be installed immediately.

Attention: The IPv6 network address changes with the update, so that any port releases via the FritzBox must be adapted to the new address. Only then will Umbrel be accessible from outside again.

UmbrelOS 1.4 brings some new features for the personal “home server”:

• Create, upload and organize files and documents.
• Share folders over your local network and easily add them as network drives on macOS, Windows, iOS or Android.
• Set up a shared folder as a Time Machine backup location on macOS.
• Preview all your photos, videos, PDFs and audio files.
• Access to app data folders.
• Support for external (USB) storage for Umbrel Home users.

Regardless of whether you use UmbrelOS or Start9OS for your own Bitcoin Node. Currently, I strongly recommend that you install the update to LND 0.18.5 beta, as a security vulnerability has been fixed here.

With Bitcoin, you as a company can accept payments in Bitcoin/Lightning independently of banks and credit card companies. Free of charge and in a matter of seconds.

I would be happy to help you develop a Bitcoin strategy for your company so that you are securely positioned for the future. I can also provide technical support and regularly install updates.
