Guile-SDL2 0.3.1 released

[Thompson, David]

Hello Guilers,

I'm happy to announce that Guile-SDL2 0.3.1 has been released!  This
is a simple maintenance release that adds support for the upcoming
Guile 3.0 featuring JIT compilation.  However, one new SDL2 binding
has snuck in.  Thanks to Eero Leno for wrapping the
SDL_SetRenderDrawColor function!

Happy hacking!
