When did Gianthold Tor change?

[NomadDog]

For the life of me, I cannot remember exactly when Gianthold Tor was changed from the two runed squares/giant skeleton ending to the two pillars/portal keeper giant ending. Was it when Epic GH was released?

• Slay the Gatekeeper

to

• Destroy the crystals (2)
• Slay the Portal Master
