Binaries need updating
I meet some problems like other issues, and I guess the reason is:

- ##  API have updated
According to [CHANGELOG](https://github.com/kitao/pyxel/blob/master/CHANGELOG.md), APIs already updated 4 days ago. It did.

- ## Binaries have not updated
I found that "libpyxelcore.dll" didn't change since 10s days.
Maybe some new features have no update in it.
