They have developed a blanket material that is much more resistant
to damage.  It is currently used on the payload bay doors of the
Columbia and Challenger orbiters and covers most of the white areas
on Discovery.  I am not aware of them replacing the higher temperature
black tiles with the blankets as of yet (I could be wrong). (I was
in the OPF 2 weeks ago but only saw Challenger..I was told this
information by a NASA person who had been in the other bay where
Discovery was being 'smoke tested', i.e. powered up for the first 
time at KSC).
