  After briefly reviewing work I've done recently with Krishna Rajagopal on the
nature of the equilibrium phase transition in QCD at finite temperature and
zero baryon number and on the possibility of forming misaligned vacuum by a
quench, I discuss -- also briefly -- two new items. These are extension of the
arguments concerning the order of the transition to to 2+1 dimensions, relating
in this case gauge to conformal field theories, that could be explored in
numerical experiments; and the energy budget at the chiral transition and its
relevance to the nature of the transition and to quenching.
