+### What's new in this version
+
+In this version, we mainly enhanced and tuned the APIs of font rendering.
+
+#### Tunning the logical font APIs
+
+The styles of LOGFONT changed.
+
+* Add new rendering style:
+  1. `FS_RENDER_ANY`: Not specified
+  1. `FS_RENDER_MONO`:
+  1. `FS_RENDER_GREY`:
+  1. `FS_RENDER_SUBPIXEL`:
+* Some old styles are deprecated:
+  1. `FS_WEIGHT_BOOK`; use `FS_RENDER_GREY` instead.
+  1. `FS_WEIGHT_SUBPIXEL`; use `FS_RENDER_SUBPIXEL` instead.
+* Introduced or redefined the weight styles to follow OpenType specification:
+  1. `FONT_WEIGHT_ANY`: Not specified
+  1. `FONT_WEIGHT_THIN`: Thin.
+  1. `FONT_WEIGHT_EXTRA_LIGHT`: Extra light (Ultra Light).
+  1. `FONT_WEIGHT_LIGHT`: Light.
+  1. `FONT_WEIGHT_REGULAR`: Regular (Normal).
+  1. `FONT_WEIGHT_MEDIUM`: Medium.
+  1. `FONT_WEIGHT_DEMIBOLD`: Demi Bold (Semi Bold)
+  1. `FONT_WEIGHT_BOLD`: Bold.
+  1. `FONT_WEIGHT_EXTRA_BOLD`: Extra Bold (Ultra Bold).
+  1. `FONT_WEIGHT_BLACK`: Black (Heavy).
+* Introduce the new decoration styles and replace 
+`FONT_UNDERLINE_LINE` and `FONT_STRUCKOUT_LINE` with them:
+  1. `FONT_DECORATE_ANY`: Not specified.
+  1. `FONT_DECORATE_NONE`: None.
+  1. `FONT_DECORATE_UNDERLINE`: glyphs are underscored.
+  1. `FONT_DECORATE_STRUCKOUT`: glyphs are overstruck.
+  1. `FONT_DECORATE_US`: Both `FONT_DECORATE_UNDERLINE` and `FONT_DECORATE_STRUCKOUT`.
+  1. `FONT_DECORATE_OUTLINE`: Outline (hollow) glyphs.
+  1. `FONT_DECORATE_REVERSE`: Reverved for future. Glyphs have their foreground and background reversed.
+* The following style are deprecated:
+  1. `FONT_OTHER_LCDPORTRAIT`
+  1. `FONT_OTHER_LCDPORTRAITKERN`
+
+For a new app, you should use the new function `CreateLogFontEx` to
+create a LOGFONT, and specify the weight and rendering method of the glyph.
+
+For the back-compatibility, you can still use `CreateLogFont` to create a new
+LOGFONT. However, `FS_WEIGHT_BOOK` will be treated `FS_WEIGHT_REGULAR` and
+`FS_RENDER_GREY`, while `FS_WEIGHT_SUBPIXEL` will be treated
+`FS_WEIGHT_REGULAR` and `FS_RENDER_SUBPIXEL`.
+
+You can still use `CreateLogFontByName` to create a new LOGFONT.
+But the style string in the font name changed from
+
+    <weight><slant><flipping><other><underline><struckout>
+
+to
+
+    <weight><slant><flipping><other><decoration><rendering>
+
+Note that `<underline>` and `<struckout>` are merged to `<decoration>`
+in order to keep the style string is still 6-character long.
+
+Consequently, if you want to use the rendering method SUPIXEL for a TTF font,
+please define the logical font name in the following way:
+
+    ttf-Courier-rrncns-*-16-UTF-8
+
+Moreover, the family name of a DEVFONT supports aliases since 3.4.0:
+
+    <fonttype>-<family[,aliase]*>-<styles>-<width>-<height>-<charset[,charset]*>
+
+for example:
+
+    ttf-Arial,Sans Serif-rrncnn-8-16-ISO8859-1,UTF-8
+    ttf-courier,monospace,serif-rrncnn-8-16-ISO8859-1,UTF-8
+
+Note that the length of one DEVFONT name can not exceed 255 bytes.
+
+#### Changed APIs
+
+* The fields `height` and `descent` have been removed from GLYPHINFO struct.
+One should get the font metrics information by calling `GetFontMetrics` function
+if you want to get the height and descent data of one font.
+
+* More fields added for GLYPHBITMAP struct in order to return the completed
+rasterized glyph bitmap information.
+
+* `GetGlyphInfo` now can return the basic glyph type and break type of a
+UNICODE character. If the glyph is an ASCII character, the old `MCHAR_TYPE`
+can also be returned.
+
+* Rename `mg_FT_LcdFilter` to `FT2LCDFilter` in order to follow MiniGUI naming
+rules.
+
+* Rename `UChar32` to `Uchar32` and `UChar16` to `Uchar16` in order to
+avoid the conflict with typedef of UChar32 in 'unicode/umachine.h'.
+
+* Redefine `Uchar32` and `Glyph32` as `Uint32` instead of `int`.
+
+#### New APIs
+
+* `GetGlyphsByRules` function calculates and allocates the glyph string from
+a multi-byte string under the specified white space rule and transformation
+rule.
+
+* `GetGlyphsExtentPointEx` function gets the visual extent information
+of a glyph string which can fit in a line with the specified maximal extent.
+
+* `DrawGlyphStringEx` function draws a glyph string to the specific
+positions of a DC.
+
+* `CreateLogFontIndirectEx` creates a new LOGFONT by using the value of
+an existed LOGFONT but with a new rotation value.
+
+#### Others
+
+* Support for FreeType1 removed.
+
+You should always use FreeType2 to support vector fonts, such as TrueType
+fonts (TTF), TrueType collections (TTC), OpenType fonts (OTF, both TrueType
+and CFF variants), OpenType collections (OTC), and Type 1 fonts (PFA and PFB).
+
+### Other Changes
+
+* A new BITMAP type: `BMP_TYPE_REPLACEKEY`. When `bmType` of a BITMAP object
+has this bit set, any pixel which is equal to `bmColorKey` will be replaced by
+`bmColorRep`.
