  * changed the electroweak FCNC dipole basis to {{{(ctA...,ctZ...)}}} instead of {{{(ctW...,ctZ...)}}}}
  * added five-point interactions (thanks to CMS TOP EFT group, Florencia Canelli, Reza Goldouzian, Abideh Jafari, Seth Moortgat)
- * added a configuration option to switch from the {{{(aEWM1,Gf,MZ)}}} electroweak inputs to the {{{(Gf,MZ,MW)}}}. See {{{configuration.py}}} for the hack, to be used with great care.
- * added a configuration option to normalize all chromo-dipole operator coefficients ({{{ctG}}} and FCNC cousins) with a factor of the strong coupling {{{G}}}. This is currently required for jet merging not to crash. Note however that the jet merging code was not written with non-SM interactions in mind. So results it produces with chromo-dipole operators should be validated. See {{{configuration.py}}} for the hack, to be used with great care.
+ * added a configuration option to switch from the {{{(aEWM1,Gf,MZ)}}} electroweak inputs to the {{{(Gf,MZ,MW)}}} ones. As inputs are different, different numerical results will be obtained in the two cases. See {{{configuration.py}}} for the hack, to be used with great care.

This is currently required for jet merging not to crash. Note however that the jet merging code was not written with non-SM interactions in mind. So results it produces with chromo-dipole operators should be validated. Note also that {{{G}}} runs and that its value at the scale {{{MZ}}} depends on the parton distribution function employed.

 - 2018-08-23: added back {{{DIM6}}} coupling orders to the {{{dim6top_LO_UFO_each_coupling_order}}} version (thanks to Jay Howarth)
 - 2018-06-06: corrected the Lorentz structures of the operators relative to {{{cbtud1}}} and {{{cbtud8}}} coefficients from scalar to vector (thanks to Céline Degrande)
