'Changes' link in 'Your' menu goes to https://gerrit.wikimedia.org/dashboard/self, which is 404. Correct URL is https://gerrit.wikimedia.org/r/dashboard/self. Other links are similarly wrong. The top "PolyGerrit" link has correct URL though.
Also for some reason the links open new window/tab, which is not what they used to do and I don't think it's right either.
