Hugo 0.25 is the Kinder Surprise: It automatically opens the page you're working on in the browser, it adds full AND and OR support in page queries, and you can now have templates per language.

If you start with hugo server --navigateToChanged, Hugo will navigate to the relevant page on save (see animated GIF). This is extremely useful for site-wide edits. Another very useful feature in this version is the added support for AND (intersect) and OR (union) filters when combined with where.

Example:

{{ $pages := where .Site.RegularPages "Type" "not in" (slice "page" "about") }}
{{ $pages := $pages | union (where .Site.RegularPages "Params.pinned" true) }}
{{ $pages := $pages | intersect (where .Site.RegularPages "Params.images" "!=" nil) }}

The above fetches regular pages not of page or about type unless they are pinned. And finally, we exclude all pages with no images set in Page params.

This release represents 36 contributions by 12 contributors to the main Hugo code base. @bep still leads the Hugo development with his witty Norwegian humor, and once again contributed a significant amount of additions. But also a big shoutout to @yihui, @anthonyfok, and @kropp for their ongoing contributions. And as always a big thanks to @digitalcraftsman for his relentless work on keeping the documentation and the themes site in pristine condition.

Hugo now has:

• 18209+ stars
• 455+ contributors
• 168+ themes
