title: "Hugo 0.51: The 30K Stars Edition!"
description: "Bug fixes, new template functions and more error improvements."
categories: ["Releases"]
---
Hugo reached [30 000 stars on GitHub](https://github.com/gohugoio/hugo/stargazers) this week, which is a good occasion to do a follow-up release of the great Hugo `0.50`. This is mostly a bug fix release, but it also adds some useful new functionality, two examples are the new template funcs [complement](https://gohugo.io/functions/complement/) and [symdiff](https://gohugo.io/functions/symdiff/). This release also continues the work on improving Hugo's error messages. And with `.Position` now available on shortcodes, you can also improve your own error messages inside your custom shortcodes:
```bash
{{ with .Get "name" }}
{{ else }}
{{ errorf "missing value for param 'name': %s" .Position }}
{{ end }}
```
When the above fails, you will see an `ERROR` log similar to the below:
```bash
ERROR 2018/11/07 10:05:55 missing value for param name: "/sites/hugoDocs/content/en/variables/shortcodes.md:32:1"
```
This release represents **31 contributions by 5 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 [@krisbudhram](https://github.com/krisbudhram), [@LorenzCK](https://github.com/LorenzCK), and [@coliff](https://github.com/coliff) for their ongoing contributions.
And a big thanks to [@digitalcraftsman](https://github.com/digitalcraftsman) and [@onedrawingperday](https://github.com/onedrawingperday) for their relentless work on keeping the themes site in pristine condition and to [@kaushalmodi](https://github.com/kaushalmodi) for his 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 **6 contributions by 5 contributors**. A special thanks to [@ikemo3](https://github.com/ikemo3), [@maiki](https://github.com/maiki), [@morya](https://github.com/morya), and [@regisphilibert](https://github.com/regisphilibert) for their work on the documentation site.
