It’s the last day of the giveaway, if I’m not mistaken. But it’s also turned up in the latest Humble Bundle which also includes some other nice stuff. The version there is also slightly updated:
Dear Esther: Landmark Edition has been remade with the Unity engine, featuring a full audio remaster, and the addition of a brand-new Directors’ Commentary mode, allowing players to explore the island and learn what inspired the game and how it was crafted by The Chinese Room and Rob Briscoe.
