# Original version notes:
**Welcome to Kryptonite 2.0.0!**
This version completely overhauls the Kryptonite Optimisation System making is quicker and easier to use than ever before! Here's what's new:
* Both the Kryptonise Optimisation System (KOS) and the Exploit Database (EDB) now have a GUI that can be accessed in-game (command-line access for console is still in!)
* Introducing KOS Manual Mode, a mode which allows you to tweak **hundreds** of specific optimisaton values from CraftBukkit, Spigot, Paper, Purpur, and Pufferfish! This mode also provides guidance on recommended ranges that these values should be within based on a combination Eternity and YouHaveTrouble's guides.
* KOS Auto can now load new profiles faster.
* KOS now applies patches faster.
* Added three new EDB exploits: EDB-10 (Anti-Nether roof access), EDB-11 (Anti-Xray), EDB-12 (Anti-Impersonation).
We've also fixed a number of bugs and improved the overall performance of the software!
*Please note: Some commands have changed in this version. See the Wiki for more information.*
