Proposed addition to release manager processes: Clearly articulate (in the release notes?) which operating systems and browsers (and versions & bitness of each) are supported by a given release. Not just Linux distros, which should have one or more distro champions; but also Windows (to answer anticipated questions like: "Is the staff client supported on Windows 8 64-bit?"); and a line in the sand for old browsers (Internet Explorer 6 anyone?) and potentially cutting-edge releases (
IE 10? Ubuntu Raring?). This also assumes that any statements of support have corresponding testing.
