Release Notes

hexojs/hexo

v4.2.1

Compare Source

Fix

• Fix compatibility with Node 14 [#​4285]

v4.2.0

Compare Source

Features

• Caching is disabled by default in hexo-server [#​3963]
  • It's disabled so that any changes (particularly to the theme's layout) can be previewed in real-time.
  • If you use hexo-server in production environment to serve your website, it can be enabled by,

  _config.yml
  server:
    cache: true

• Add min_depth: option to toc() helper [#​3997]
  • Example usage:

  <%- toc(page.content, { min_depth: 2 }) %>
  // table of content would only include <h2>, <h3> and above

Fixes

• Merges similar theme configs in main config and theme's config [#​3967]

  • For example:

  _config.yml
  theme_config:
    a:
      b: 'foo'

  • Plus,

  _config.yml of theme
  a:
    c: 'bar'

  • theme variable should have,

  a: {
    b: 'foo',
    c: 'bar'
  }
  

• Fixes some caching issue [#​3985]

• Open Graph now applies all pretty_urls options to og:url tag [#​3983]

Refactor

• No longer uses lodash [#​3969], [#​3987], [#​3753]

  • Lodash _ is still available as a global variable, usually utilized in theme layout.
  • However, we plan to completely drop it in the coming Hexo 5.0.0
  • This project page includes all the relevant pull requests which you may find useful

• Completely drops cheerio [#​3850], [#​3677]

  • This means Hexo no longer includes cheerio as part of its production dependencies (it's still a development dependency)
  • This also means the following initialization methods no longer work,

  const cheerio = require('./node_modules/hexo/node_modules/cheerio/index')
  const cheerio = require('./node_modules/cheerio/index')

  • To use cheerio,

  $ npm install --save cheerio

  const cheerio = require('cheerio')

v4.1.1

Compare Source

Feature

• Add trailing_html: to pretty_urls: option to remove ".html" from url [#​3917]
  • Use the following config to remove the trailing ".html" from permalink variables

  _config.yml
  pretty_urls:
    trailing_html: false

  • Example: https://yoursite.com/page/about.html -> https://yoursite.com/page/about

Fixes

• Set default locales (in "language_TERRITORY" format) for og:locale Open Graph tag [#​3921]
  • Previously og:locale was inserted only if language: is configured in "language-TERRITORY" format
  • With this fix, if the language is "en", og:locale will default to "en_US". Refer to the pull request for the full list.
• meta_generator() helper should output the correct Hexo version [#​3925]
• permalink_defaults: option should be parsed, not replaced [#​3926]
• "node_modules/" and ".git/" folders in themes/ are now always ignored [#​3918]

Refactor

• Further reduces lodash usage [#​3880]

v4.1.0

Compare Source

Breaking change

• Requires Node 8.10 or above [#​3778]
  • Node 8 is going to be deprecated in less than a month, we strongly urge to upgrade to Node 10 or newer
• og:locale Open Graph tag won't be inserted if language: (in config, front-matter of post/page or open_graph() helper) is not in language-TERRITORY format [#​3808]
  • en is invalid
  • en-GB is valid
  • Not all locales are supported (e.g. en-AU is not valid), see official list
  • Dash (e.g. "en-GB") must be used for multilingual support, dash is automatically transformed to underscore (e.g. "en_GB") in og:locale
  • Verify the corresponding file exists in the languages/ folder of installed theme before changing the language: config

Features

• Support adding hour and minute to post permalink [#​3629]
  • Example usage:

  _config.yml
  permalink: :year/:month/:day/:hour/:minute/:title/

  • Results in https://yoursite.com/2019/12/09/23/59/a-post/
• Insert article:published_time [#​3674] article:author [#​3805] Open Graph tags
• Enable lazyload in iframe-related tag plugins [#​3798]
  • Affects iframe, jsfiddle, vimeo, youtube tag plugins
  • Requires supported browsers to benefit from this feature
  • Unsupported browsers would simply ignore the attribute, thus it is safe to use and always enabled
• meta_generator helper to insert metadata element tag [#​3782]
  • Example usage:
  • Insert the following snippet (if EJS is used) inside <head> element of your theme layout,

  <%- meta_generator() %>

  • would output <meta name="generator" content="Hexo 4.1.0">
  • Hexo 3.9.0+ inserts the tag automatically; to get the performance benefit (of the meta_generator helper), meta_generator: option should be disabled,

  _config.yml
  meta_generator: false

• Support custom attributes in js() [#​3681] and css() [#​3690] helpers
  • Example usage:

  <%- js({ src: 'script.js', integrity: 'foo', async: true }) %>
  // <script src="/script.js" integrity="foo" async></script>
  
  <%- css({ href: 'style.css', integrity: 'foo' }) %>
  // <link rel="stylesheet" href="/style.css" integrity="foo">

• Support wrap: option to enable/disable wrapping backtick codeblock in <table> element [#​3827]
  • Enabled by default, enabling line_number also enables it
  • Configure in highlight:

  _config.yml
  highlight:
    line_number: false # must be disabled to disable wrap:
    wrap: false

  • This option also can be passed to codeblock() tag plugin [#​3848]

  {% codeblock lang:js wrap:false %}
  const foo = (bar) => {
    return bar;
  };
  {% endcodeblock %}

Fixes

• Retain blank lines in a codeblock attached in blockquote [#​3770]
• Replaced deprecated og_updated_time Open Graph tag with article:modified_time [#​3674]
• Replaced deprecated keywords Open Graph tag with article:tag [#​3805]
• meta_generator tag should be inserted into <head> that spans multiple lines [#​3778]
• No longer clear database db.json when running hexo new or hexo --help [#​3793]
• Completely ignore files/folders specified in ignore: option [#​3797]
  • If you're using Webpack or related tools in your theme, the node_modules folder could cause some issues
  • A temporary workaround is to configure Hexo to ignore that folder,

  _config.yml
  ignore: '**/themes/*/node_modules/**'

  • The workaround will no longer be necessary in future version
• jsfiddle, vimeo and youtube tag plugins now use https only [#​3806]
• external_link filter should not process data URLs (e.g. mailto: & javascript:) [#​3812] and <article> element [#​3895]
• Prevent unnecessary insertion of front-matter when using alias in Hexo CLI [#​3830]
  • -p is alias of --path
  • -s is alias of --slug
  • -r is alias of --replace
• Applies include: and exclude: options to post's asset folder [#​3882]
• ignore: option should work for files, in addition to folders [#​3878]

Housekeeping

• Add FOSSA license analyzer for open-source software license compliance [#​3779]
• Run benchmark in CI to catch regression [#​3776]
• Further reduces lodash usage [#​3786], [#​3788], [#​3790], [#​3785], [#​3809], [#​3791], [#​3810], [#​3826], [#​3867], [#​3845]
• Remove unnecessary file at the end of unit test [#​3792]
• Add funding source to npm [#​3851]
