Hugo 0.16
Releases
/0-16/

Hugo 0.16 is our best and biggest release ever. The Hugo community has outdone itself with continued performance improvements, beautiful themes for all types of sites from project sites to documentation to blogs to portfolios, and increased stability.

This release represents over 550 contributions by over 110 contributors to the main Hugo code base. Since last release Hugo has gained 3500 stars, 90 contributors and 23 additional themes.

This release celebrates 3 years since {{< gh "@spf13" >}} wrote the first lines of Hugo. During those 3 years Hugo has accomplished some major milestones including...

  • 10,000+ stars on GitHub
  • 320+ contributors
  • 90+ themes
  • 1000s of happy websites
  • Many subprojects like {{< gh "@spf13/cobra">}}, {{< gh "@spf13/viper">}} and {{< gh "@spf13/afero">}} which have experienced broad usage across the Go ecosystem.

{{< gh "@bep" >}} led the development of Hugo for the 3rd consecutive release with nearly half of the contributions to 0.16 in addition to his considerable contributions as lead maintainer. {{< gh "@anthonyfok" >}}, {{< gh "@DigitalCraftsman" >}}, {{< gh "@MooreReason" >}} all made significant contributions. A special thanks to {{< gh "@abourget" >}} for his considerable work on multilingual support. Due to its broad impact we wanted to spend more time testing it and it will be included in Hugo's next release.

Highlights

Partial Builds: Prior to this release Hugo would always reread and rebuild the entire site. This release introduces support for reactive site building while watching (hugo server). Hugo will watch the filesystem for changes and only re-read the changed files. Depending on the files change Hugo will intelligently re-render only the needed portion of the site. Performance gains depend on the operation performed and size of the site. In our testing build times decreased anywhere from 10% to 99%.

Template Improvements: Template improvements continue to be a mainstay of each Hugo release. Hugo 0.16 adds support for the new block keyword introduced in Go 1.6 -- think base templates with default sections -- as well as many new template functions.

Polish: As Hugo matures releases will inevitably contain fewer huge new features. This release represents hundreds of small improvements across ever facet of Hugo which will make for a much better experience for all of our users. Worth mentioning here is the curious bug where live reloading didn't work in some editors on OS X, including the popular TextMate 2. This is now fixed. Oh, and now any error will exit with an error code, a big thing for automated deployments.

0.15.0 November 25, 2015

The v0.15.0 Hugo release brings a lot of polish to Hugo. Exactly 6 months after the 0.14 release, Hugo has seen massive growth and changes. Most notably, this is Hugo's first release under the Apache 2.0 license. With this license change we hope to expand the great community around Hugo and make it easier for our many users to contribute. This release represents over 377 contributions by 87 contributors to the main Hugo repo and hundreds of improvements to the libraries Hugo uses. Hugo also launched a new theme showcase and participated in Hacktoberfest.

Hugo now has:

  • 6700 (+2700) stars on GitHub
  • 235 (+75) contributors
  • 65 (+30) themes

Template Improvements: This release takes Hugo to a new level of speed and usability. Considerable work has been done adding features and performance to the template system which now has full support of Ace, Amber and Go Templates.

Hugo Import: Have a Jekyll site, but dreaming of porting it to Hugo? This release introduces a new hugo import jekyllcommand that makes this easier than ever.

Performance Improvements: Just when you thought Hugo couldn't get any faster, Hugo continues to improve in speed while adding features. Notably Hugo 0.15 introduces the ability to render and serve directly from memory resulting in 30%+ lower render times.

Huge thanks to all who participated in this release. A special thanks to {{< gh "@bep" >}} who led the development of Hugo this release again, {{< gh "@anthonyfok" >}}, {{< gh "@eparis" >}}, {{< gh "@tatsushid" >}} and {{< gh "@DigitalCraftsman" >}}.

New features

  • new hugo import jekyll command. {{< gh 1469 >}}
  • The new Param convenience method on Page and Node can be used to get the most specific parameter value for a given key. {{< gh 1462 >}}
  • Several new information elements have been added to Page and Node:
    • RuneCount: The number of runes in the content, excluding any whitespace. This may be a good alternative to .WordCount for Japanese and other CJK languages where a word-split by spaces makes no sense. {{< gh 1266 >}}
    • RawContent: Raw Markdown as a string. One use case may be of embedding remarkjs.com slides.
    • IsHome: tells the truth about whether you're on the home page or not.

Improvements

  • Hugo now supports dynamic reloading of the config file when watching.
  • We now use a custom-built LazyFileReader for reading file contents, which means we don't read media files in /content into memory anymore -- and file reading is now performed in parallel on multicore PCs. {{< gh 1181 >}}

    • Several new Blackfriday options are added:
      • Option to disable Blackfriday's Smartypants.
      • Option for Blackfriday to open links in a new window/tab. {{< gh 1220 >}}
      • Option to disable Blackfriday's LaTeX style dashes {{< gh 1231 >}}
      • Definition lists extension support.
  • Scratch now has built-in map support.
  • We now fall back to link title for the default page sort. {{< gh 1299 >}}
  • Some notable new configuration options:
    • IgnoreFiles can be set with a list of Regular Expressions that matches files to be ignored during build. {{< gh 1189 >}}
    • PreserveTaxonomyNames, when set to true, will preserve what you type as the taxonomy name both in the folders created and the taxonomy key, but it will be normalized for the URL. {{< gh 1180 >}}
  • hugo gen can now generate man files, bash auto complete and markdown documentation
  • Hugo will now make suggestions when a command is mistyped
  • Shortcodes now have a boolean .IsNamedParams property. {{< gh 1597 >}}

New Template Features

    • The new pluralize and singularize template funcs.
    • The new base64Decode and base64Encode template funcs.
    • The sort template func now accepts field/key chaining arguments and pointer values. {{< gh 1330 >}}
    • Several fixes for slicestr and substr, most importantly, they now have full utf-8-support. {{< gh 1190 1333 1347 >}}
    • The new last template function allows the user to select the last N items of a slice. {{< gh 1148 >}}
    • The new after func allows the user to select the items after the Nth item. {{< gh 1200 >}}
    • Add time.Time type support to the where, ge, gt, le, and lt template functions.
    • It is now possible to use constructs like where Values ".Param.key" nil to filter pages that doesn't have a particular parameter. {{< gh 1232 >}}
    • getJSON/getCSV: Add retry on invalid content. {{< gh 1166 >}}
    • The new readDir func lists local files. {{< gh 1204 >}}
    • The new safeJS function allows the embedding of content into JavaScript contexts in Go templates.
    • Get the main site RSS link from any page by accessing the .Site.RSSLink property. {{< gh 1566 >}}
  • Ace templates:
    • Base templates now also works in themes. {{< gh 1215 >}}.
    • And now also on Windows. {{< gh 1178 >}}

  • page.HasMenuCurrent() and node.HasMenuCurrent() now work correctly in multi-level nested menus.
  • Support Fish and Chips style section titles. Previously, this would end up as Fish And Chips. Now, the first character is made toupper, but the rest are preserved as-is. {{< gh 1176 >}}
  • Hugo now removes superfluous p-tags around shortcodes. {{< gh 1148 >}}

Notices

  • hugo server will watch by default now.
  • Some fields and methods were deprecated in 0.14. These are now removed, so the error message isn't as friendly if you still use the old values. So please change:
    • getJson to getJSON, getCsv to getCSV, safeHtml to safeHTML, safeCss to safeCSS, safeUrl to safeURL, Url to URL, UrlPath to URLPath, BaseUrl to BaseURL, Recent to Pages.

Known Issues

Using the Hugo v0.15 32-bit Windows or ARM binary, running hugo server would crash or hang due to a memory alignment issue in Afero. The bug was discovered shortly after the v0.15.0 release and has since been fixed by {{< gh "@tpng" >}}. If you encounter this bug, you may either compile Hugo v0.16-DEV from source, or use the following solution/workaround:

  • 64-bit Windows users: Please use hugo_0.15_windows_amd64.zip (amd64 == x86-64). It is only the 32-bit hugo_0.15_windows_386.zip that crashes/hangs (see {{< gh 1621 >}} and {{< gh 1628 >}}).
  • 32-bit Windows and ARM users: Please run hugo server --renderToDisk as a workaround until Hugo v0.16 is released (see “hugo server” returns runtime error on armhf and {{< gh 1716 >}}).
You can’t perform that action at this time.
