In this update:-

Footsteps have been added, a few people have requested this.
Stretch Achievements requiring players to visit and discover areas they may not have previously known existed.

Going forwards:-

This is hopefully the last patch for a little bit as I plan to switch to developing the Next major version change, The Major release is either going to be over Christmas or just after. I Intend on keeping compatibility with currently played maps, However at worst users will be able to switch to previous versions or the game to open older maps.
