Also from OhMyGod comes a screenshot of 'boost mode' for PS4 Pro which provides a higher frame rate for older PlayStation 4 games that don't have a Pro patch yet with a list of changed games available on ThisGenGaming.com.
Here's the official announcement from Sony VP John Koller, to quote: PS4 System Software Update 4.50 Features Detailed
Starting today, those of you selected for our beta program will get an early peek at some of the new features coming to PS4 with our next major system software update, version 4.50 (codenamed Sasuke).

From the Readme.txt, to quote: How to build
1) Go into ps4ninja_win\Browser\PS4NINJA and type
This will build minlib, ps4ninja (PS4 part) and create payload_176.bin.
2) To build the windows application, open the VS Solution and build it.
3) You can manually build any of the components by entering into the directory and type "make".
