  - Remove country/region flags since the original filename have encoding issue which can cause a build failure, and also to avoid some potential regional internationalization issues. (216e1a9)
  - Resolution display as -1x-1 for some images with unregular filename (e.g. `2IGYT%BD]SYY77Q7R041(WD.jpg` and `G9E@W$_Y4GYMWJY)%R24X~2.jpg`): Recompile under newer Qt version should works. Original Caesium official binary comes with Qt 5.1.0, Recompiled and tested under Qt 5.15.2.
  - Click "Auto preview" checkbox and then click any image item will lead a crash. (0e3d5c5)
+ - Rework the language selection part, no longer depends on language filename and no longer have encoding issue. (c641be3)
+ - Port away from deprecated Qt APIs. (53a7ee1)
+ - Update zh_CN translations, align translation locale code to the one descripted inside the ts file. (1074ddd)
 
+### Non-issue changes
+
+ - UI tweaks: Hi-DPI-aware window size and text, use Qt logo from Qt built-in resource.
+ - (temporary) disable update checker (since this is a forked version and the update checker request the orginal version url for checking updates).
