	The last Hugo release of the year brings a new [images.Overlay](https://gohugo.io/functions/images/#overlay) filter to overlay an image on top of another, e.g. for watermarking, and [Dart Sass](https://gohugo.io/hugo-pipes/scss-sass/#options) support.

This release represents **29 contributions by 12 contributors** to the main Hugo code base. [@bep](https://github.com/bep) leads the Hugo development with a significant amount of contributions, but also a big shoutout to [@moorereason](https://github.com/moorereason), and [@davidsneighbour](https://github.com/davidsneighbour) for their ongoing contributions.
And a big thanks to [@digitalcraftsman](https://github.com/digitalcraftsman) for his relentless work on keeping the themes site in pristine condition and to [@davidsneighbour](https://github.com/davidsneighbour), [@coliff](https://github.com/coliff) and [@kaushalmodi](https://github.com/kaushalmodi) for all the great work on the documentation site.

Many have also been busy writing and fixing the documentation in [hugoDocs](https://github.com/gohugoio/hugoDocs), 
which has received **22 contributions by 6 contributors**. A special thanks to [@bep](https://github.com/bep), [@D4D3VD4V3](https://github.com/D4D3VD4V3), [@chrischute](https://github.com/chrischute), and [@azenk](https://github.com/azenk) for their work on the documentation site.
