+### 0.4.0
+- Buffer data type changed from u16 to u8
+    - **Public API**: `load_image_area`, `load_image`, and `memory_burst_write` functions are now using u8 as buffer type
+    - Memory usage is reduced by half (1kByte max. instead of 2kByte)
+- **Behavior** Calling `init` no longer clears the eink display. Instead call `reset` directly.
