+## I. Overview
+Openvela has been dedicated to introducing support for more chips, enhancing system real-time communication capabilities, and significantly improving system robustness, storage functionality, and debuggability. This release focuses on enhancements around the following core themes:
+- Hardware Ecosystem Expansion: **Added support for [Infineon AURIX™ TC4](../quickstart/development_board/tc4d9_evb_guide.md), [Flagchip MCU](../quickstart/development_board/fc7300f8m_evb_guide.md), and QEMU-R52 SIL platforms**, broadening the scope of platform applicability.
+- System Kernel Hardening: **Achieved collaborative operation of SMP and PM, introduced MPU-based thread stack protection and RPC framework refactoring**, making the system safer and more stable.
+- Key Capabilities Integration: **Added SocketCAN and Ethernet protocol stacks; introduced the highly reliable NVS2 storage solution**.
+- Developer Experience Optimization: Provided low-overhead FDX real-time tracing tools and multiple LVGL application examples, lowering the barrier for development and debugging.
+
+## II. Major New Features & Enhancements
+### **1. Platform Support**
+- Added support for <text underline="true">Infineon</text> AURIX™ TriCore™ TC4 chips
+- Added support for <text underline="true">Flagchip</text> MCUs
+- Added Cortex-R52 core support under QEMU platform, supporting Vector SIL platform
+- Resolved compilation issues for nuttx boards, better supporting native nuttx boards platforms
+### **2. Kernel & Security**
+- Power Management (PM) & Symmetric Multi-Processing (SMP):
+  - Achieved simultaneous enablement of SMP and PM functions, and completed functional verification on the `qemu-armv8a` platform, covering basic PM functions and `ostest` base cases.
+- RPC
+  - Framework Refactoring: Refactored the RPC framework to possess greater versatility, enabling cross-core communication capabilities for other VirtIO devices.
+  - Functional Enhancements for Rptun/Rpmsg: Introduced a multi-priority mechanism to meet the real-time needs of automotive scenarios, and fixed issues from functional safety code scans.
+- Memory Management Enhancements: Implemented Task-independent Heap space, now supported by libraries like `libdbus`.
+- Binder Message Mechanism: Integrated Binder server/client fds into the `libuv` event loop, handling messages via callbacks, achieving unified management with other modules.
+- Added Rpmsg Battery & Gauge drivers.
+- Inter-thread Isolation Protection Mechanism
+  The kernel now supports thread stack protection based on the hardware Memory Protection Unit (MPU). When a thread experiences a stack overflow, this mechanism triggers a hardware exception, preventing it from corrupting other threads' stack spaces or critical data.
+- Code Quality:
+  - Completed multiple static code issue fixes, improving the overall quality of the code base.
+### **3. Communication**
+- Added SocketCAN and Ethernet Support
+  Introduced a CAN communication framework following standard Socket APIs. Users can now use standard interfaces like `socket()`, `bind()`, `send()`, `recv()` for CAN message transmission and filtering.
+- WebSocket Function Enhancement
+  Added default certificate support for the WebSocket Feature, simplifying the secure connection establishment process.
+### **4. Storage**
+- Added NVS2 (Non-Volatile Storage v2)
+  Integrated a brand-new, highly reliable NVS2 storage solution. This storage solution is deeply optimized for embedded Flash media, supporting wear leveling, power-loss safety, and data encryption.
+### **5. Debugging & Diagnostics**
+- Added FDX-based Real-time Trace Function
+  Implemented a low-intrusion real-time tracing tool based on the FDX (Fast Debug eXchange) protocol. It can capture and export high-precision system events, such as task switching, interrupt response, semaphore operations, etc., with extremely low system overhead.
+## **6. Application Examples**
+- Added [Breakout Game](./../../../../../packages_demos/blob/trunk-5.4/breakout/Readme.md): A touchscreen breakout game developed based on openvela and LVGL, which has implemented basic game logic, added image assets, and implemented impact sound effects.
+- Added [Virtual Pet](./../../../../../packages_demos/blob/trunk-5.4/pet/README.md) application: An interactive demo program based on the LVGL graphics library, simulating the process of raising a digital pet. Users can care for the virtual pet through operations like feeding, giving water, exercise, and rest to improve its mood and level.
+- [Snake Game](./../../../../../packages_demos/blob/trunk-5.4/snake_game/Readme.md): An automatic Snake game implemented using the LVGL graphics library.
+- [Electronic Wooden Fish](./../../../../../packages_demos/blob/trunk-5.4//wooden_fish/README_zh-cn.md): Based on the openvela `nxaudio` service and the upper-layer LVGL UI framework, implementing a complete interaction link containing responsive layout and secure resource management, realizing an application showcase with smooth animation effects, secure resource management, and a good user experience.
