Recently GitHub Pages upgraded to Jekyll 3.5.2, and we’ve now made it our default to match.
This update includes a few enhancements and bug fixes, most notably one which should dramatically speed up generation of your site! In testing jekyllrb.com, generation went from 18 seconds down to 8.
For a full list of revisions check out the release notes.
If you are still using Jekyll 3.4, here’s everything that’s new in 3.5 so far:
- Jekyll now uses Liquid 4, the latest! It comes with whitespace control, new filters
concatandcompact, loop performance improvements and many fixes. - Themes can specify dependencies and Jekyll will require those. This makes it easier for theme writers to use plugins.
- The
gemskey in the_config.ymlis nowplugins. This is backwards-compatible, as Jekyll will gracefully upgrade gems to plugins if you use the former. - Filters like sort now allow you to sort based on a subvalue, e.g.
{% assign sorted = site.posts | sort: "image.alt_text" %}. - You can now use tab-separated data files.
- Using
layout: nonewill now produce a file with no layout. Equivalent tolayout: null, with the exception that none is a truthy value and won’t be overwritten by front matter defaults. - Dramatically faster site generation!
- Lots more bug fixes.
For most sites, no action is required to take advantage of the latest version. As always, if you wish to use a different version of Jekyll for your site, you can define that in your Gemfile.
As a reminder, sites on our Team and higher plans can also use custom (non-approved) gems. See learn.siteleaf.com for all the details.
