<ul><li>A warning is issued if the lattice parameter seems to be a conversion<br>
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</li><li>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.</li></ul>
<h1><font size="4">Problems fixed in 6.4.1 branch :</font></h1>
<ul><li>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.</li><li>Restart of ph.x with 2D boundary conditions has been fixed (see gitlab<br>
issue #102)</li><li>XML file correctly written if tetrahedra are used (see gitlab issue #103)</li></ul>Paolo<br></div><div>-- <br><div dir="ltr" class="gmail_signature"><div dir="ltr"><div><div dir="ltr"><div>Paolo Giannozzi, Dip.
