What it means

Who it affects, what changes and what is still unconfirmed

Each sentence links inside to the piece that supports it.

Users running older Core Lightning nodes are the ones who notice this first, because the warning is aimed at operators on version 26.06.7 or earlier. For them, the immediate change is that they are told to upgrade right away if they are still on those releases.

Before this alert, older Core Lightning releases were simply available for use; after it, operators of those versions are told to move off them immediately. What does not change from the text is that the warning is limited to affected older releases, not every Lightning node.

The move was larger before the first headline than after. That is an observation, not an explanation: the market also moves on things nobody publishes.
