  Over the last decade a number of important observational results have been
reported using data from the Pierre Auger Observatory. We shall review some of
the recent key findings that have significantly advanced our understanding of
ultra-high energy cosmic rays and that have called into question the
`classical' interpretation of the flux-suppression above 5x10^{19} eV as being
caused (solely) by the Greisen-Zatsepin-Kuzmin effect. Instead, the data
suggest seeing mostly the maximum energy of extragalactic cosmic ray
accelerators. This has a number of implications, ranging from reduced prospects
of doing particle physics with cosmogenic neutrinos to reduced chances of
seeing the sources of ultra-high energy cosmic rays at all. To address these
emerging and pressing scientific questions, the Pierre Auger Observatory is
presently being upgraded to AugerPrime. It will enable composition measurements
into the flux-suppression region and also improve the particle physics
capabilities. An Engineering Array has been deployed and is taking data. Full
construction will start late 2017.
