Latest version on bitcoin.org now is 0.17.0.1 but I have seen no announcement of that here. The signatures seem OK from first glance, upgrading now...
Releases like 0.17.0.x are just packaging respins, so they don't get announcements. Basically nothing was changed in it but something about the OSX installer.
However, 0.17.1 is done now-- and tagged in git for over a day-- holiday travel is just delaying getting the binaries up, which is why it hasn't been announced yet. They should be up by christmas however!
