What's new

Version 26.06.6+2 weeks ago

If Core Lightning asks for a password after updating, don’t worry—this is a browser session bug and does not affect your node or funds. Core Lightning does not require a separate password on Umbrel; open the app in a private/incognito window or clear your Umbrel’s site data in the browser.

What's changed:

Rejects channel openings that reuse an existing funding outpoint, avoiding channel ID collisions.
Handles unexpected duplicate peer connections more gracefully.
