+# Changelog
+## :carrot: v0.3.0
+  - ### :bulb: Features
+    Refactor the boot strapping code to support `Aarch32` and `Aarch64` build target architectures.
+    
+    The boot strapping code is run at the very first moment the Raspberry Pi boots up and the GPU
+    hands over execution to the CPU. The boot strapper could be built to run in `singlecore` mode.
+    
+    The boot strapping switches all cores into exception level EL1(aarch64)/SVC(aarch32) and
+    initializes the MMU with a default 1:1 mapping accross the whole available memory.
+
+    The boot strapping also sets up exception handling and provides a generic default exception
+    handler that is ready to be implemented by the user of this crate.
+
+    The miniUart of the Raspberry Pi is initialized and attached to the global CONSOLE which enables
+    users of this crate to use the macros `print!`and `println!` to conviniently write to the uart console. The feature
+    set of both macros is equivalent to the `rust_std` versions.
