Pretty close to being a thing of the past. The handful that still have daily newscasts are generally outside productions - "NJ Spotlight News" on what's now NJ PBS (ex-NJTV, ex-NJN) or"Cronkite News" on KAET in Phoenix (produced by the Cronkite J-school at ASU, which shares a building and ownership with KAET). The University of Florida J-school was producing a daily half-hour for WUFT, the UF-owned PBS station in Gainesville, but I don't see it on the schedule now (perhaps because it's summer break?)
It looks like Lakeland PBS in northern Minnesota still has a nightly "Lakeland News," a survivor of that small breed of public stations in areas that were unserved/underserved by commercial TV and started their own newscasts in the 70s and 80s. Once upon a time, that was also NJN News, the Delaware Tonight newscast on WHYY, and a few others, but the vast majority of PBS stations have decided they can better allocate public affairs resources in other ways, whether it's documentaries or weekly shows. And even the weekly shows are fading away - the studio show we did at WXXI-TV in Rochester quietly ended a couple of years ago with little outcry.
