+## Version 5.0.9
+
+On Jan. 14 2022, FMSoft announces the availability of MiniGUI 5.0.9,
+which is a bug fixing release with minor enhancements of MiniGUI 5.0.x.
+
+### What's new in version 5.0.9
+
+In this version, we fixed some bugs:
+
+* BUGFIXING:
+   - Fix a crash bug in `InitSubDC()` of `src/newgdi/gdi.c`.
+* ENHANCEMENTS:
+* OPTIMIZATIONS:
+* TUNING:
+   - Change copyright year to 2022.
+
+## Version 5.0.8
+
+The MiniGUI development team announces the availability of MiniGUI 5.0.8,
+which is a bug fixing release with minor enhancements of MiniGUI 5.0.x.
+
+### What's new in version 5.0.8
+
+In this version, we fixed some bugs and made some optimizations and enhancements:
+
+* BUGFIXING:
+* ENHANCEMENTS:
+   - Support for WebP image format based on `libwebp`.
+   - Support for two ARM64-based hardware platforms: PX30 and R818.
+   - New surface pixel format for main window: `ST_PIXEL_XRGB565` under compositing schema.
+* OPTIMIZATIONS:
+   - Shrink heap size for fixed string.
+   - Optimize the memory use of blitting context.
+* TUNING:
+   - Tune code of fbcon video engine for compositing schema.
+   - Fix warnings and errors for conditional compilation.
+
+## Version 5.0.6
+
+The MiniGUI development team announces the availability of MiniGUI 5.0.6,
+which is the bug fixing release of MiniGUI 5.0.x.
+
+### What's new in version 5.0.6
+
+In this version, we fixed some bugs and made some optimizations and enhancements:
+
+* BUGFIXING:
+   - Fix bugs of switching layers under MiniGUI-Processes.
+   - Fix bugs of `FBCon` and `PC_XVFB` engines: the dirty rectangles are
+     not set empty after calling `SyncUpdate`.
+   - Fix memory leaks when using block heap.
+   - Fix a bug in ServerGetWinZNodeRegion.
+* ENHANCEMENTS:
+   - Enhance `GetGlyphInfo` to return the FreeType face, font file path, and glyph
+     index.
+   - NEW API `StretchBltEx` to support different scaling filters and rotation.
+   - Use Pixman to support color blending methods for `BitBlt` and `StretchBlt`.
+   - Enhance fallback compositor to support animation when switching among layers.
+   - New API `SetMainWindowGestureFlags` and `MSG_GESTURETEST` message for
+     gesture test and setting the gesture flags of a specific main window.
+   - Tune implementation of Tooltip window.
+* OPTIMIZATIONS:
+   - Optimize the fallback compositor for lucent windows.
+   - Use Pixman to optimize `FillBox`, `BitBlt`, and `StretchBlt`.
+   - Optimize the management of BLOCKHEAP.
+   - Optimize the `__mg_lookfor_unused_slot`.
+
+Note that the binary backward-compatibility was broken, two operations added to
+`CompositorOps`. You should rebuild all MiniGUI applications.
+
+Also note that the compositing schema is now enabled by default.
