Release new version

[jirutka]

Could you please release a new version? It's almost a year since the last release. I have problem with outdated source-map dependency that does't work well with Rollup, so I have to hack it somehow.

Sorry for the delay. When I wanted to release in the weekend, I noticed several security warnings when running "npm install". I'll try to do the release today.

Tonight, that is. In about 7 hours

Thanks!
