Hans changed many of the namespaces from short to longer forms and what you did in your simple slides module isn’t good style anymore

simpleslides-s-default.tex:

\def\simpleslidestitlecomponent#1%
  {\simpleslidestitleparameter{\c!before#1}
      \startalignment[\simpleslidestitleparameter{#1\c!align}]
        \doattributes{\??vars:simpleslides:title:}{#1\c!style}{#1\c!color}
          {\getvariable{simpleslides:title}{#1}}
       \stopalignment
    \simpleslidestitleparameter{\c!after#1}}

The best is to replace your \setvariables based setup commands with a \getparameters based variant, for mkiv there are many helper functions in mult-aux.mkiv.
