v0.18

0.18.0 December 19th 2016

Today, we’re excited to release the much-anticipated Hugo 0.18!

We’re heading towards the end of the year 2016, and we can look back on three releases and a steady growing community around the project. This release includes over 220 contributions by nearly 50 contributors to the main codebase. Since the last release, Hugo has gained 1750 stars and 27 additional themes.

Hugo now has:

• 13750+ stars
• 408+ contributors
• 137+ themes

@bep once again took the lead of Hugo and contributed a significant amount of additions. Also a big shoutout to @digitalcraftsman for his relentless work on keeping the documentation and the themes site in pristine condition, and also a big thanks to @moorereason and @bogem for their contributions.

We wish you all a Merry Christmas and a Happy New Year.
The Hugo team

Highlights

The primary new feature in Hugo 0.18 is that every piece of content is now a Page ( #2297 ). This means that every page, including the home page, can have a content file with frontmatter. Not only is this a much simpler model to understand, it is also faster and paved the way for several important new features:

• Enable proper titles for Nodes #1051
• Sitemap.xml should include nodes, as well as pages #1303
• Document homepage content workaround #2240
• Allow home page to be easily authored in markdown #720
• Minimalist website with homepage as content #330

Hugo again continues its trend of each release being faster than the last. It’s quite a challenge to consistently add significant new functionality and simultaneously dramatically improve performance. Running this benchmark with these sites (renders to memory) shows about 60% reduction in time spent and 30% reduction in memory usage compared to Hugo 0.17.

Other New Features

• Every Page now has a Kind property. Since everything is a Page now, the Kind is used to differentiate different kinds of pages. Possible values are page, home, section, taxonomy, and taxonomyTerm. (Internally, we also define RSS, sitemap, robotsTXT, and 404, but those have no practical use for end users at the moment since they are not included in any collections.)
• Add a GitInfo object to Page if enableGitInfo is set. It then also sets Lastmod for the given Page to the author date provided by Git. #2291
• Implement support for alias templates #2533
• New template functions:
• Add imageConfig function #2677
• Add sha256 function #2762
• Add partialCached template function #1368
• Add shortcode to display Instagram images #2690
• Add noChmod option to disable perm sync #2749
• Add quiet build mode #1218

Notices

• .Site.Pages will now contain several kinds of pages, including regular pages, sections, taxonomies, and the home page. If you want a specific kind of page, you can filter it with where and Kind. .Site.RegularPages is a shortcut to the page collection you have been used to getting.
• RSSlink is now deprecated. Use RSSLink instead. Note that in Hugo 0.17 both of them existed, so there is a fifty-fifty chance you will not have to do anything (if you use a theme, the chance is close to 0), and RSSlink will still work for two Hugo versions.

Fixes

• Revise the base template lookup logic so it now better matches the behavior of regular templates, making it easier to override the master templates from the theme #2783
• Add workaround for block template crash. Block templates are very useful, but there is a bug in Go 1.6 and 1.7 which makes the template rendering crash if you use the block template in more complex scenarios. This is fixed in the upcoming Go 1.8, but Hugo adds a temporary workaround in Hugo 0.18. #2549
• All the Params configurations are now case insensitive #1129 #2590 #2615
• Make RawContent raw again #2601
• Fix archetype title and date handling #2750
• Fix TOML archetype parsing in hugo new #2745
• Fix page sorting when weight is zero #2673
• Fix page names that contain dot #2555
• Fix RSS Title regression #2645
• Handle ToC before handling shortcodes #2433
• Only watch relevant themes dir #2602
• Hugo new content creates TOML slices with closing bracket on new line #2800

Improvements

• Add page information to error logging in rendering #2570
• Deprecate RSSlink in favor of RSSLink
• Make benchmark command more useful #2432
• Consolidate the Param methods #2590
• Allow to set cache dir in config file
• Performance improvements:
• Avoid repeated Viper loads of sectionPagesMenu #2728
• Avoid reading from Viper for path and URL funcs #2495
• Add partialCached template function. This can be a significant performance boost if you have complex partials that does not need to be rerendered for every page. #1368

Documentation Updates

• Update roadmap #2666
• Update multilingual example #2417
• Add a “Deployment with rsync” tutorial page #2658
• Refactor /docs to use the block keyword #2226

v0.17

Hugo is going global with our 0.17 release. We put a lot of thought into how we could extend Hugo to support multilingual websites with the most simple and elegant experience. Hugo’s multilingual capabilities rival the best web and documentation software, but Hugo’s experience is unmatched. If you have a single language website, the simple Hugo experience you already love is unchanged. Adding additional languages to your website is simple and straightforward. Hugo has been completely internally rewritten to be multilingual aware with translation and internationalization features embedded throughout Hugo.

Hugo continues its trend of each release being faster than the last. It’s quite a challenge to consistently add significant new functionality and simultaneously dramatically improve performance. @bep has made it his personal mission to apply the Go mantra of “Enable more. Do less” to Hugo. Hugo’s consistent improvement is a testament to his brilliance and his dedication to his craft. Hugo additionally benefits from the performance improvements from the Go team in the Go 1.7 release.

This release represents over 300 contributions by over 70 contributors to the main Hugo code base. Since last release Hugo has gained 2000 stars, 50 new contributors and 20 additional themes.

Hugo now has:

• 12,000 stars on GitHub
• 370+ contributors
• 110+ themes

@bep continues to lead the project with the lionshare of contributions and reviews. A special thanks to @bep and @abourget for their considerable work on multilingual support.

A big welcome to newcomers @MarkDBlackwell , @bogem and @g3wanghc for their critical contributions.

Highlights

Multilingual Support: Hugo now supports multiple languages side-by-side. A single site can now have multiple languages rendered with full support for translation and i18n.

Performance: Hugo is faster than ever! Hugo 0.17 is not only our fastest release, it’s also the most efficient. Hugo 0.17 is nearly twice as fast as Hugo 0.16 and uses about 10% less memory. This means that the same site will build in nearly half the time it took with Hugo 0.16. For the first time Hugo sites are averaging well under 1ms per rendered content.

Docs overhaul: This release really focused on improving the documentation. Gohugo.io is more accurate and complete than ever.

v0.16

0.16.0 June 6th 2016

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 codebase. Since last release Hugo has gained 3500 stars, 90 contributors and 23 additional themes.

This release celebrates 3 years since @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 @spf13/cobra , @spf13/viper and @spf13/afero which have experienced broad usage across the Go ecosystem.

@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. @anthonyfok , @DigitalCraftsman , @MooreReason all made significant contributions. A special thanks to @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.

@jdoss has kindly uploaded and built the Hugo .rpm pack�ages to the Fedora Copr.¹ Please visit https://copr.f...

v0.15

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 @bep who led the development of Hugo this release again, @anthonyfok, @eparis, @tatsushid and @DigitalCraftsman.

New features

• new hugo import jekyll command. #1469
• The new Param convenience method on Page and Node can be used to get the most specific parameter value for a given key. #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. #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 server now builds ~30%+ faster by rendering to memory instead of disk. To get the old behavior, start the server with --renderToDisk=true.
• 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. #1181
• Hugo is now built with Go 1.5 which, among many other improvements, have fixed the last known data race in Hugo. #917
• Paginator now also supports page groups. #1274
• Markdown improvements:
  • Hugo now supports GitHub-flavoured markdown code fences for highlighting for md-files (Blackfriday rendered markdown) and mmark files (MMark rendered markdown). #362 #1258
  • Several new Blackfriday options are added:
    • Option to disable Blackfriday's Smartypants.
    • Option for Blackfriday to open links in a new window/tab. #1220
    • Option to disable Blackfriday's LaTeX style dashes #1231
    • Definition lists extension support.
• Scratch now has built-in map support.
• We now fall back to link title for the default page sort. #1299
• Some notable new configuration options:
  • IgnoreFiles can be set with a list of Regular Expressions that matches files to be ignored during build. #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. #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. #1597

New Template Features

• All template engines:
  • The new dict function that could be used to pass maps into a template. #1463
  • 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. #1330
  • Several fixes for slicestr and substr, most importantly, they now have full utf-8-support. #1190 #1333 #1347
  • The new last template function allows the user to select the last N items of a slice. #1148
  • The new after func allows the user to select the items after the Nth item. #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. #1232
  • getJSON/getCSV: Add retry on invalid content. #1166
  • The new readDir func lists local files. #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. #1566
• Ace templates:
  • Base templates now also works in themes. #1215.
  • And now also on Windows. #1178
• Full support for Amber templates including all template functions.
• A built-in template for Google Analytics. #1505
• Hugo is now shipped with new built-in shortcodes: #1576
  • youtube for YouTube videos
  • vimeo for Vimeo videos
  • gist for GitHub gists
  • tweet for Twitter Tweets
  • speakerdeck for Speakerdeck slides

Bugfixes

• Fix data races in page sorting and page reversal. These operations are now also cached. #1293
• 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. #1176
• Hugo now removes superfluous p-tags around shortcodes. #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 @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 #1621 and #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 #1716).

v0.14

The v0.14.0 Hugo release brings of the most demanded features to Hugo. The foundation of Hugo is stabilizing nicely and a lot of polish has been added. We’ve expanded support for additional content types with support for AsciiDoc, Restructured Text, HTML and Markdown. Some of these types depend on external libraries as there does not currently exist native support in Go. We’ve tried to make the experience as seamless as possible. Look for more improvements here in upcoming releases.

A lot of work has been done to improve the user experience, with extra polish to the Windows experience. Hugo errors are more helpful overall and Hugo now can detect if it’s being run in Windows Explorer and provide additional instructions to run it via the command prompt.

The Hugo community continues to grow. Hugo has over 4000 stars on github, 165 contributors, 35 themes and 1000s of happy users. It is now the 5th most popular static site generator (by Stars) and has the 3rd largest contributor community.

This release represents over 240 contributions by 36 contributors to the main Hugo codebase.

Big shout out to @bep who led the development of Hugo this release, @anthonyfok, @eparis, @SchumacherFM, @RickCogley & @mdhender for their significant contributions and @tatsushid for his continuous improvements to the templates. Also a big thanks to all the theme creators. 11 new themes have been added since last release and the hugoThemes repo now has previews of all of them.

Hugo also depends on a lot of other great projects. A big thanks to all of our dependencies inclding:
cobra, viper, blackfriday, pflag, HugoThemes, BurntSushi/Toml, goYaml, and the Go standard library.

New features

• Support for all file types in content directory.
  • If dedicated file type handler isn’t found it will be copied to the destination.
• Add AsciiDoc support using external helpers.
• Add experimental support for Mmark markdown processor
• Bash autocomplete support via genautocomplete command
• Add section menu support for a Section Menu for "the Lazy Blogger"
• Add support for Ace base templates
• Adding RelativeURLs = true to site config will now make all the relative URLs relative to the content root.
• New template functions:
  • getenv
  • The string functions substr and slicestr
    *seq, a sequence generator very similar to its Gnu countepart
  • absURL and relURL, both of which takes the BaseURL setting into account

Improvements

• Fix crossrefs on Windows.
• Fix eq and ne template functions when used with a raw number combined with the result of add, sub etc.
• Fix paginator with uglyurls
• Fix #998, supporting UTF8 characters in Permalinks.

Notices

• To get variable and function names in line with the rest of the Go community, a set of variable and function names has been deprecated: These will still work in 0.14, but will be removed in 0.15. What to do should be obvious by the build log; 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, Indexes to Taxonomies.

v0.13

The v0.13.0 release is the largest Hugo release to date. The release introduced
some long sought after features (pagination, sequencing, data loading, tons of
template improvements) as well as major internal improvements. In addition to
the code changes, the Hugo community has grown significantly and now has over
3000 stars on github, 134 contributors, 24 themes and 1000s of happy users.

This release represents 448 contributions by 65 contributors

A special shout out to @bep and
@anthonyfok for their new role as Hugo
maintainers and their tremendous contributions this release.

New major features

• Support for data files in YAML,
  JSON, or TOML
  located in the data directory (#885)

  from remote sources via GetJson and GetCsv in short codes or other layout
  files (#748)
• Pagination support for home page, sections and
  taxonomies (#750)
• Universal sequencing support
  • A new, generic Next/Prev functionality is added to all lists of pages
    (sections, taxonomies, etc.)
  • Add in-section Next/Prev content pointers
