Hugo 0.30 is the Race Car Edition. Hugo is already very very fast, but much wants more. So we added Fast Render Mode. It is hard to explain, so start the Hugo development server with hugo server and start editing. Live reloads just got so much faster! The “how and what” is discussed at length in other places, but the short version is that we now re-render only the parts of the site that you are working on.
The second performance-related feature is a follow-up to the Template Metrics added in Hugo 0.29. Now, if you add the flag --templateMetricsHints, we will calculate a score for how your partials can be cached (with the partialCached template func).
This release also more or less makes the really fast Chroma highlighter a complete alternative to Pygments. Most notable is the new table linenos support (7c30e2cb@bep#3915), which makes copy-and-paste code blocks much easier.
This release represents 31 contributions by 10 contributors to the main Hugo code base.
@bep leads the Hugo development with a significant amount of contribution, but also a big shoutout to @moorereason, @digitalcraftsman, and @bmon 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.
Running hugo server will now run with the new “Fast Render Mode” default on. To turn it off, run hugo server --disableFastRender or set disableFastRender=true in your site config.
There have been several fixes and enhancements in the Chroma highlighter. One is that it now creates Pygments compatible CSS classes, which means that you may want to re-generate the stylesheet. See the Syntax Highlighting Doc.
