  This paper can be viewed as a sequel to the author's long survey on the
Zimmer program \cite{F11} published in 2011. The sequel focuses on recent rapid
progress on certain aspects of the program particularly concerning rigidity of
Anosov actions and Zimmer's conjecture that there are no actions in low
dimensions. Some emphasis is put on the surprising connections between these
two different sets of developments and also on the key connections and ideas
for future research that arise from these works taken together.
