I've been using it in production for svgbob. There have been a lot of breaking changes for the past month, but things are starting to stabilize[0] in the 0.43.x release. Hopefully the version stays at 0.43.x and no more breaking changes, due to using better, appropriate or more descriptive names in Struct and functions.
