+## 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.
+
+## Version 5.0.5
+
+The MiniGUI development team announces the availability of MiniGUI 5.0.5,
+which is the bug fixing release of MiniGUI 5.0.x.
+
+### What's new in version 5.0.5
+
+In this version, we fixed some bugs and made some minor enhancements:
+
+* BUGFIXING:
+   - Adjust the constants for `WS_XXXX` macros to avoid duplicated values.
+
+Note that the binary backward-compatibility was broken. You should
+rebuild all MiniGUI applications.
+
+## Version 5.0.4
+
+The MiniGUI development team announces the availability of MiniGUI 5.0.4,
+which is the bug fixing release of MiniGUI 5.0.x.
+
+### What's new in version 5.0.4
+
+In this version, we fixed some bugs and made some minor enhancements:
+
+* BUGFIXING:
+   - Fix bugs in ServerGetWinZNodeRegion: must check for possible empty mask rect
+     and bad assignment of maskrect
+   - Fix a potential bug: only increase `nr_mask_rects` for not empty mask rectangle.
+   - Fix a bug: update surface of controls surface in `travel_children_with_priv_cdc`.
+* ENHANCEMENTS:
+  - New IAL engine: `--enable-singletouchkeyial` to build the IAL engine for
+    single touch screen and key buttons.
+
+## Version 5.0.3
+
+The MiniGUI development team announces the availability of MiniGUI 5.0.3,
+which is the bug fixing release of MiniGUI 5.0.x.
+
+### What's new in version 5.0.3
+
+In this version, we fixed some bugs and made some minor enhancements:
+
+* BUGFIXING:
+   - Always check expired timers even got `EINTR`.
+   - Add static modifier to `refresh_dirty_region` method of the fallback compositor.
+   - Fix a bug in `RegisterListenFD`.
+   - Fix a bug in `allocate_more_fd_slots`.
+* TUNING:
+  - Rebuild the private data for all visible z-nodes after selected a new compositor.
+* ENHANCEMENTS:
+  - New configuration option: `--enable-mgslicefallback` to build a fallback
+    implementation of mgslice.
+  - New API: `ServerGetTopmostZNodeOfType`.
+  - Merge some code by @ehello (<https://github.com/ehello>) for FreeRTOS.
