Meaning if there was no 2.4.1 build for a device, no build is currently available for the device.
FP2 is marked as legacy.
They would have done this, but the servers went down.
Anyway … Even the last version is missing so many security updates now that it is pretty irresponsible towards everybody else to use this old stuff when connected to the internet (last security updates on FP2 are from February 2024, later /e/OS builds had no security updates anymore). I can only hope Fairphone 2s are too slow for botnets to really exploit such negligence.
To continue using your Fairphone 2 halfway responsibly there seems to be only one OS left.
