This has already been linked from the forum and the autobuilds page, but still great news. We only have space on the server to host the most recent two images for each router. However, user carp4 has donated a significant amount of space on a Google Drive to host all of the older images. Without further ado:
It will take two to three months to upload all of the older images – there are almost half of a terabyte worth already. They’re all on a local drive now, so will trickle online during off-peak hours overnight. I rough estimate would be end of June, 2023 to have them all online, if all goes well.
