Two updates in this patch:

• Fixed a backtracking issue at the lower-right part of the map that could cause players to get stuck at a save point.
• Map tweak to make a late-game powerup more intuitive and provide room for an associated tutorial on the powerup.

I don't like making map changes post-release, so this will be the only one.  I just had a real problem with the way this upgrade was handled, and I wish I had caught this pre-release.  But it is what it is.    The fixes should have no effect on saved games and you should be able to progress as normal, but if you do encounter errors due to the update, please let me know.
