Still, attempts to use BL3YP with pw.x from versions 4.1.1 or 4.2.1 of QE and with calculation=”scf” result in the error message from setup.f90: “HYBRID XC not implemented in PWscf”. Was B3LYP removed from recent distributions, or I miss something else? I could not find any information on this


You need to compile Q/E with -DEXX in the DFLAGS of your make.sys file.  Then, all of the implemented hybrid functionals will be open to you, and you can experience the joys of converging the k-point mesh for the Fock integral.  See examples/EXX_example/README for more information.
