RouterOS v6.31rc7

I see this version is available for download on the website, but only rc6 shows up under package updates.

Yep, something’s changed on the website.
Until now there were links to “6latest” package files, without any info about the version of the file.
Now v6.31rc7 is openly available on the website, and the “6latest” link still directs to v6.31rc6.

Won’t the “6latest” links be updated any more?
