Deus Ex: Mankind Divided – PC Patch Build 582.1 Changelog:
The following gameplay fixes are in this patch:
 

    Players can now also close their in-game menus using the keys to open it: TAB / I / M / O / P / L.
    Fixed an issue where the diagonal walk speed was too fast, causing Jensen to make noise.
    Fixed a crash at the shooting range.
    Fixed an issue where Rucker would not spawn in certain situations.
    Fixed an issue where the tranquilizer rifle would no longer shoot in certain situations.
    Fixed an issue in System Rift where the “Heat Sensor” strategy page would not trigger after loading a savegame.
    ‘Hold E’ to open Mission Objectives/Pocket Secretaries/Strategy Pages/Etc. are mapped to the TAB key by default. This removes the interference with ‘Hold E’ to drag bodies.
