Since patch 7.36 affected basically every hero in the game, it's no surprise that 7.37 is mostly focused on getting the playing field leveled again. A bunch of heroes are getting new innates and facets, and there's even a rework of Medusa. 7.37 also includes more informative tooltips, which should give you a better moment-to-moment understanding of all the variables that go into murdering someone in a forest.
