Functional Changes ---------- ------- - make 'imply' not impose any restrictions: allow symbols implied by y to become m - change "modules" from sub-option to first-level attribute Bugfixes -------- - nconf: fix core dump when searching in empty menu - nconf: stop endless search loops - xconfig: fix content of the main widget - xconfig: fix support for the split view mode Other Changes ----- ------- - highlight xconfig 'comment' lines with '***' - xconfig: navigate menus on hyperlinks - xconfig: drop support for Qt4 - improve host ncurses detection Update the 'option modules' usage to just 'modules' in Config.in.
