---

Hugo 0.57 brings **Cascading Front Matter**, **Alphabetical Sorting**, **Resources Loading from Assets with Wildcards**. And more.

**Cascading Front Matter**: We have added a new and powerful `cascade` keyword to Hugo's front matter. This can be added to any index node in `_index.md`. Any values in `cascade` will be merged into itself and all the descendants.

```yaml
title: "My Blog"
icon: "world.png"
cascade:
   icon: "flag.png"
   outputs: ["HTML"]
   type: "blog"
 ```
 
It's worth noting that the `cascade` element itself will also be merged. Also, to grasp the full value of this feature, remember that front matter in Hugo is both **data** and **behaviour**: You can tell Hugo how to process a subset of the pages (some example keywords are `layout`, `type`, `outputs`, `weight`) using the `cascade` keyword, e.g. _"I want this subsection to be rendered in both the `HTML` and `Calendar` Output Formats"_.
 
This feature is created by[@regisphilibert](https://github.com/regisphilibert) and [@bep](https://github.com/bep) See [#6041](https://github.com/gohugoio/hugo/issues/6041) for details.

**Resources Loading from Assets with Wildcards**: We have added two new sought after template functions to the `resources` namespace: `resources.Match` and `resources.GetMatch`. These behaves like their namesake methods on `Page` (with [super-asterisk wildcard support](https://github.com/gobwas/glob)), but searches in all the resources in Assets. E.g. `{{ $prettyImages := resources.Match "images/**pretty.jpg" }}` will give a slice of all "pretty pictures". Another relevant example: `{{ $js := resources.Match "libs/*.js" | resources.Concat "js/bundle.js" }}`.

**Performance:** In general, this version is slightly faster and more memory effective. In particular, we have fixed a performance issue with the replacer step that greatly improves the build speed of certain large and content-rich sites (thanks to [@vazrupe](https://github.com/vazrupe) for the fix).  

This release represents **46 contributions by 8 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 [@muesli](https://github.com/muesli), [@XhmikosR](https://github.com/XhmikosR), and [@vazrupe](https://github.com/vazrupe) 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 **13 contributions by 7 contributors**. A special thanks to [@regisphilibert](https://github.com/regisphilibert), [@bep](https://github.com/bep), [@kenberkeley](https://github.com/kenberkeley), and [@davidsneighbour](https://github.com/davidsneighbour) for their work on the documentation site.

Hugo now has:

* 37336+ [stars](https://github.com/gohugoio/hugo/stargazers)
* 440+ [contributors](https://github.com/gohugoio/hugo/graphs/contributors)
* 334+ [themes](http://themes.gohugo.io/)

## Notes

* All string sorting in Hugo is now alphabetical/lexicographical.
* `home.Pages` now only returns pages in the top level section. Before this release, it included _all regular pages in the site_. This made it easy to list all the pages on home page, but it also meant that you needed to take special care if you wanted to navigate the page tree from top to bottom. If you need _all regular pages_, use `.Site.RegularPages`.  Also see [#6153](https://github.com/gohugoio/hugo/issues/6153).
* `.Pages` now include sections. We have added `.RegularPages` as a convenience method if you want the old behaviour. See [#6154](https://github.com/gohugoio/hugo/issues/6154) for details.
* Hugo now only "auto create" sections for the home page and the top level folders. The other sections need a `_index.md` file. See [#6171](https://github.com/gohugoio/hugo/issues/6171) for details.
