I think the main user-visible change in fontconfig was that freetype now 
defaults to using the autohinter module (you can comment it out 
in /etc/fonts/local.conf by putting <!--  and --> around the <match 
target="font"> ... "autohint" ... </match> lines.)  I don't know what the 
KControl module does to enable/disable sub-pixel rendering, but you can also 
comment out that section of the local.conf file, too, if it is uncommented.

Relevant portion of changelog:
   * fontconfig.templates: default the autohinter to "true", but keep the
     subpixel rendering to "false". This is because the bytecode interpreter
     (previous default) renders very badly on TFT screens, and the subpixel
     rendering looks bad on non-RGBA screens (closes: #268321).
