Other than the layout and look-and-feel change (again?),
302 redirection for qdn.qnx.com had been silently removed.
(not a big deal, seldom used nowadays)
And RTP 6.1 docs, including the stale but useful “System Administration Guide”
had been all wiped out (again).
I still miss the design 2 generations ago (cf. developers.qnx.com)
as it matches better with Photon design…
