Most of what was addressed in the patch were bug fixes and balances to gameplay. Skill power is no longer increased permanently when the Death by Proxy talent is in use, and experience is now awarded to those who complete all side quests in the Midtown East safehouse.
Here’s an overview of the patch taken from the UbiBlog:
On top of the Dark Zone features just described, players can now heal other neutral players in the Dark Zone using First Aid and Support Station skills. Items extracted from the Dark Zone are now properly described as “new” items when moved to a player’s inventory, and the Dark Zone funds and Experience rewards from surviving Rogue status and killing rogue agents have been improved.
Bug fixes were also implemented across PC, Xbox One and PlayStation 4 versions of the game. The PC game client now keeps track of PC graphic settings and applies optimal settings for the player’s configuration. Players can now reconnect to servers after suspending the game on Xbox One. On PlayStation 4, an issue where the ISAC volume would get a bit loud when playing with a headset has also been rectified.
