guile-json 4.0.0 released

[Aleix Conchillo Flaqué]

Hi!

I'm super excited to announce guile-json 4.0.0. This new version comes with
a couple of small breaking changes and huge performance improvements (up to
6x faster).

Huge thanks to Linus Björnstam who brought up the performance issues plus a
bunch of suggestions of how to improve them and followed along all the way.
