Yes, VHDL-2008 was ratified


  "In February 2008, Accellera approved VHDL 4.0 also informally known
  as VHDL 2008, which addressed more than 90 issues discovered during
  the trial period for version 3.0 and includes enhanced generic types.
  In 2008, Accellera released VHDL 4.0 to the IEEE for balloting for
  inclusion in IEEE 1076-2008. The VHDL standard IEEE 1076-2008 was
  published in January 2009."
