First post, so if this is in the wrong place please let me know.
Around July 18 some checksum files stopped being "archived"(for lack of a better word). To see what I mean please check out:
These are just examples of what is happening. The *-latest.tar.xz.hash.txt file(s) are there, but when downloading older images, not all have a checksum file for verification. As I haven't checked all sub-archs I don't know how wide spread this issue is. Haswell appears not to have been affected so far.
Just thought I should bring this to someone's attention. Again if this is posted in the wrong place, let me know.
