bootstrap-vue toast component missing?

[monokal]

Hey guys, great work and thank you for making this freely available.

I'm trying to use this component exactly as documented:
https://bootstrap-vue.js.org/docs/components/toast/

However, my browser console shows "TypeError: Cannot read property 'toast' of undefined" and as far as I can see the toast component is missing.

Is this expected? Are some bootstrap-vue removed from the free version?

Thanks.
