A warning is issued if the lattice parameter seems to be a conversion
factor instead of a true lattice parameter. Conversion should be achieved
with the appropriate options, not with dirty tricks. In the future this
will no longer be allowed
A warning is issued if ibrav=0 is used for systems having symmetry. If not
properly done this may lead to strange problems with symmetry detection
and symmetrization. Lattice information should be used if available.
Problems fixed in 6.4.1 branch :
Two bugs fixed in HP: 1) the code was not working correctly when fractional
translations were present, 2) there was a bug in the case when either there
is only one k point, or when k pools are used and some of the pools have
only one k point.
Restart of ph.x with 2D boundary conditions has been fixed (see gitlab
XML file correctly written if tetrahedra are used (see gitlab issue #103)
