As of the update of [extra/qbs], [libre/qtcreator] needs a rebuild.
Without a rebuild, I get the following error message when opening qtcreator:

/usr/lib/qtcreator/plugins/libQbsProjectManager.so: Cannot load library
/usr/lib/qtcreator/plugins/libQbsProjectManager.so: (libqbscore.so.1.14:
cannot open shared object file: No such file or directory)

A rebuild of [libre/qtcreator] solves this issue. When rebuilding qtcreator, please note the patch for updating qtcreator to the newest version 4.11.0:
