 Makefile
 ======================================
-I added the -std=c++17 flag to enable better constexpr support.
-
-Clang Tidy
+- Added the -std=c++17 flag to enable better constexpr support.
+- Removed optimizations as the system would crash with them.
+  The BlueScreen would show an empty callstack on crashes with -O2 so I guess the problem is the missing ebp or something like that.
+  
+Changes
 ======================================
-The compile_commands.json is used by clang-tidy.
-To generate it from the makefile, use bear: "bear -- make".
-There are two options that clang doesn't know: -mpreferred-stack-boundary=2 and -mmanual-endbr.
-These should be removed from the compile_commands.json so clang-tidy won't throw errors for every file.
+- Removed the Input.h/Input.cc files
+- Made device classes singletons
+- Changed the multitasking assembly (use stack instead of thread_state)
+- Extensive changes to the scheduling:
+  - Merged dispatcher into the scheduler
+  - Scheduler no longer uses queue but vector
+  - Scheduler owns threads
+  - Threads are addressed by tid
+  - Threads are deallocated automatically when killed/exited
+  - Retrieve threads from the scheduler without deallocation
+  - Scheduler manages blocked threads
+
+Additions
+======================================
+- Some stream manipulators for CGA_Stream (color) and OutStream (fixed width)
+- Logging class with support for colored serial port output
+- Main menu to start demo
+- A very basic system to broadcast keyboard events to threads
+- Basic implementation of vector with iterator support
+- Basic implementation of unique_ptr
+- Basic implementation of fixed size array
+
+Bugs
+======================================
+- Can't exit the PCSPKdemo
+- Random bluescreens that are hard to pinpoint
+- Tree Allocator (uses a red black tree to find best-fit blocks) crashes when freelist root is removed
