  The launch of Chandra and XMM-Newton has led to important new findings
concerning the X-ray emission from supernova remnants. These findings are a
result of the high spatial resolution with which imaging spectroscopy is now
possible, but also some useful results have come out of the grating
spectrometers of both X-ray observatories, despite the extended nature of
supernova remnants. The findings discussed here are the evidence for slow
equilibration of electron and ion temperatures near fast supernova remnant
shocks, the magnetic field amplification near remnant shocks due to cosmic ray
acceleration, a result that has come out of studying narrow filaments of X-ray
synchrotron emission, and finally the recent findings concerning Fe-rich ejecta
in Type Ia remnants and the presence of a jet/counter jet system in the Type Ib
supernova remnant Cas A.
