This is just a migration of PFC to 12.0. No new objects have been added. In fact, the platform and file service components for AIX, HPUX, Solaris and ANSI Windows have been removed. Sybase hasn't release runtime PowerBuilder files for AIX, HPUX, or Solaris since 2005, and PB12 is Unicode, so the ANSI Windows objects are obsolete.
Images have been moved to a common "images" folder, and it's expected that your registry will contain an apppath entry for the PB 12 IDE that includes that directory in the application search path.
