All three platforms receive the July 2017 Update that includes some interesting features.
If you have Hitman installed, the patch should be automatically downloaded to your selected platform. It differs depending on platform: 550 MB (PS4), 950 MB (Xbox One) and 1.2GB (PC).
The update is a good news especially for Xbox One players who reported that after previous changes the game took longer to load. The problems are now resolved. It’s also much easier to unlock Professional Difficulty as you need Mastery level between 5 and 19 to approach this difficulty option.
There are tons of other changes, including trophy typography, fixes for various missions and major combat changes. You can read about all of them on the official Hitman board.
