I was checking for the current official Phenix release and the website lists 1.9-16090. However, upon downloading it seems to be 1.8.4-1496… Am I doing something silly?
No, we are. I had thought we were going to use build 1690 as the official release*, and I switched over the web pages yesterday, but then I received a couple of urgent last minute fixes. (This happens at least once per year.) So we are hoping tonight's build will be the one. 1690 is actually quite stable and well-tested overall so it is safe to use, but there are a couple of corner cases in specific programs that we would prefer not to crash.
