-=====  GUI gmolpro 2.7.0 ===== 
  
-gmolpro version 2.7.0 should be used together with Molpro2025.1. On Mac, the package you download is already bundled with this Molpro version. On Linux, gmolpro does not come bundled with Molpro, and you need a separate installation of Molpro.+===== New features of MOLPRO2025.4 =====
  
-A trajectory can be visualised, i.e. a set of xyz files appended to each other. +Bugfixes
-In the builder window, do ''Geometry/Import to builder window...''+
  
-The box in which orbitals are plotted can be enlarged so that very diffuse orbitals can be plotted.+==== Simplfied Input ====
  
-Molpro versions beyond 2025.1 will need gmolpro version at least 2.7.0 because the xml file will be split in xml and xml-sidecar+A simplified one-line input for standard calculations has been added, see [[Quickstart|QuickStart]].

 +==== New Option CCF12 in PNO-LCCSD(T)-F12 ==== 
 + 
 +A new option has been added to the PNO program, see [[Local correlation methods with pair natural orbitals (PNOs)#Options for F12 calculations|Options for F12 calculations in PNO-LCCSD(T)-F12]]. With CCF12=0  F12 is not included in the PNO-LCCSD step and the MP2 F12 correction is added to the PNO-LCCSD and PNO-LCCSD(T) energies. This is similar to a ''focal point'' approximation, where the high-level calculation is PNO-LMP2-F12 and the low-level one PNO-LCCSD(T).

 ==== Improved PNO domain selection in PNO-LCCSD(T)-F12 ==== ==== Improved PNO domain selection in PNO-LCCSD(T)-F12 ====
  
-A new option **''SORTPNO''** has been added to the PNO program (see [[local_correlation_methods_with_pair_natural_orbitals_pnos#Options for PAO/OSV/PNO generation]] for details). If this is given, first all PNOs that satisfy the occupation number criterion are added. Then further PNOs are added until the energy completeness criterion is also satisfied. With ''SORTPAO'' these PNOs are added in the order of decreasing semi-canonical energy contributions (rather than in the order of decreasing occupation numbers). In some cases this leads to a drastic reduction of some domains. For backward compatibility, the ''SORTPNO'' option is not used by default. Additionally, there a a new option **''EPNO_MIN=//value//''**. PNOs which have semi-canonical energy contributions smaller than the given value are omitted. The default value is zero.+A new option **''SORTPNO''** has been added to the PNO program (see [[local_correlation_methods_with_pair_natural_orbitals_pnos#Options for PAO/OSV/PNO generation]] for details).

 +==== Bug fixes ====
 +
 +A bug has been fixed where double hybrid DFT calculations gave different results in serial and parallel calculations. The scaling factor to the MP2 correlation energy is now applied both in serial and in parallel mode (before it was only applied in serial DH calculations). See section [[the_density_functional_program#Double-hybrid functionals (DH, DSDH)|Double-hybrid functionals (DH, DSDH)]] for more info.
