New feature:

- Now we are ready for i18n.
- The setting dialogue has been refined. Very controllable, clearly displayed disabled items, and ready to i18n.
Fixed:
- Many memory leaks have been rescued.
- Chunk caches now work well.
- Many trivial but potential bugs are fixed.
- No longer error messages will be shown on retrieving checkpoint or server information.
- Now we can check and correct tweak mismatch during the setup
Improved:
- Customisation synchronisation has got more smoother.
Tidied
- Practically unused functions have been removed or are being prepared for removal.
- Many of the type-errors and lint errors have been corrected.
- Unused files have been removed.
Note:
- From this version, some test files have been included. However, they are not enabled and released in the release build.
