+It's Eeaster, a time for mysteries and puzzles. And at first glance, this Hugo release looks a little mysterious. The core of if is a mind-twister:
+
+```go-html-template
+{{ $css := resources.Get "css/main.css" }}
+{{ $css = $css | resources.PostCSS }}
+{{ if hugo.IsProduction }}
+{{ $css = $css | minify | fingerprint | resources.PostProcess }}
+{{ end }}
+<link href="{{ $css.RelPermalink }}" rel="stylesheet" />
+```
+
+The above uses the new [resources.PostProcess](https://gohugo.io/hugo-pipes/postprocess/) template function which tells Hugo to postpone the transformation of the Hugo Pipes chain to _after the build_, allowing the build steps to use the build output in `/public` as part of its processing.
+
+The prime current use case for the above is CSS pruning in PostCSS. In simple cases you can use the templates as a base for the content filters, but that has its limitations and can be very hard to setup, especially in themed configurations. So we have added a new [writeStats](https://gohugo.io/getting-started/configuration/#configure-build) configuration that, when enabled, will write a file named `hugo_stats.json` to your project root with some aggregated data about the build, e.g. list of HTML entities published, to be used to do [CSS pruning](https://gohugo.io/hugo-pipes/postprocess/#css-purging-with-postcss). 
+
 This release represents **20 contributions by 10 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), [@jaywilliams](https://github.com/jaywilliams), and [@satotake](https://github.com/satotake) 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 [@davidsneighbour](https://github.com/davidsneighbour) and [@kaushalmodi](https://github.com/kaushalmodi) for all the great work on the documentation site.
