From MaGog's logs for 9 March:
NOTE! NEW GAME 1424868751 Shelter 2
NOTE! CHANGED title: Shelter 2 [Upcoming] ***TO*** Shelter 2 Special Edition
[For some reason, GOG created a new catalogue entry today for "Shelter 2" and at the same time changed the existing "Shelter 2" entry (upcoming for the last couple of weeks or so) to "Shelter 2 Special Edition". This means that possibly anybody who had Shelter 2 wishlisted before today, now has Shelter 2 Special Edition wishlisted, not Shelter 2]
