The [[Diablo 3]] version of the Charged Bolt was first shown at [[BlizzCon 2008]], and was still in the game by [[BlizzCon 2009|2009]]. In 2008 it had a much higher mana cost, and significantly higher damage than in 2009, indicating the spell is now more used for the "carpet effect" of previous games. It's is assumed to still be available in Blizzard's internal game build today.
