9.1.0 (2026-09-13)

Hugo 0.165.0

  • 0.165.0 This release requires a newer Hugo version.

Change

  • Change Assets are now busted by their content instead of by the time of your build, so a visitor only refetches what actually changed.

    Formerly every build appended a new id to each asset’s URL, emptying a visitor’s cache on each deployment even when no asset was different. If you referenced assets from your own partials, assetbusting.gotmpl is replaced by asset.gotmpl, which takes a resource and returns it ready to be linked. It is still honored but now issues a deprecation warning and will be removed with a future update of the theme.

    ​
    {{ with resources.Get "/css/mine.css" }}
  {{ with partial "asset.gotmpl" . }}
<link href="{{ .RelPermalink }}" rel="stylesheet">
  {{ end }}
{{ end }}

    Below static this only concerns css/custom.css, js/custom.js and the favicon and logo images; everything else there is published as before. Those are published twice, once untouched and once processed - move them to assets to avoid the superfluous copy.

    As a busted name changes with its content, a build no longer overwrites the file its predecessor wrote and both remain. Purge your output directory, e.g. by building with Hugo’s --cleanDestinationDir, or it accumulates every version you ever built - which weighs most if you commit what you build, as publishing to a GitHub Pages branch does.

  • Change The Perfect Scrollbar library is no longer shipped with the theme. All scrollbars are the ones of your browser now, styled by the theme.

    The scrollbars colors come from new theme variant variables, four for each of the three areas, the main content, the menu and the topbar flyouts. MAIN-SCROLLBAR-THUMB-color, MENU-SCROLLBAR-THUMB-color and TOPBAR-SCROLLBAR-THUMB-color color the moving thumb, MAIN-SCROLLBAR-TRACK-color, MENU-SCROLLBAR-TRACK-color and TOPBAR-SCROLLBAR-TRACK-color the track it moves in. Each of them has a -HOVER counterpart - like MAIN-SCROLLBAR-THUMB-HOVER-color or MENU-SCROLLBAR-TRACK-HOVER-color - for the respective hovered area.

    How many of those twelve colors you see an effect from depends on the scrollbar model your browser implements, so don’t expect all of them to show everywhere. Where the theme draws the menus scrollbar itself, all four of its colors apply and the thumb reacts to being hovered on its own. A browser that offers only the standard styling has no state for the thumb, so there the -HOVER colors are taken while the surrounding area is hovered instead. And where a browser draws an overlay scrollbar for the content or the topbar flyouts, it keeps its own and the four colors of that area go unused.

  • Change The theme variant configuration has a new hidden parameter.

    If set to true, the variant will not be shown in the variant switcher but is still usable, e.g. as a sub-variant of an auto mode variant.

  • Change The title above a page sidebar menu is now taken from the root page’s linkTitle front matter.

    Formerly this was documented to use the menuTitle front matter, although that was already removed in 6.0.0 in favor of Hugo’s own linkTitle. It is still honored if no linkTitle is set but now issues a deprecation warning and will be removed with a future update of the theme.

  • Change Images now carry the dimensions of their resource, so a browser can reserve the space they will take before they have arrived.

    This avoids page reflows as each image loads and affects images that resolve to a resource Hugo can measure: a page resource or a file in your assets directory, in one of the common raster formats. An SVG, a remote address or a path in your static directory has no dimensions to give and is unchanged.

  • Change The Lunr Languages where updated to 1.21.0.

    Searching with the Lunr adapter now finds terms that consist of digits only, like part or standard numbers.

New

  • New The editURL option has a new macro ${BaseDir}, containing the directory ${FilePath} is resolved against.

    Joined, the two are the location of the displayed page on your disk during build, which lets the edit button open your local editor instead of a web service.

    ​
    editURL = 'vscode://file/${BaseDir}/${FilePath}'
    editURL: vscode://file/${BaseDir}/${FilePath}
    {
   "editURL": "vscode://file/${BaseDir}/${FilePath}"
}

    The macro is written the way a URL writes a path - with forward slashes and without a leading slash - so the same setting works on Windows and on Unix-like systems.

  • New The card shortcode has a new imagealt parameter, giving the card’s image a text alternative.

  • New The theme has updated its Mermaid dependency to 11.17.2. This adds support for swimlanes, Venn, Ishikawa, Wardley, Cynefin and TreeView.

  • New The translation for Portuguese was divided into European Portuguese and Brazilian Portuguese.

  • New The search now supports the Polish language.

9.0.0 (2026-01-01)

Hugo

  • Hugo When the theme introduced compatibility with Hugo 0.146.7 it had to remove a performance optimization due to a limitation in Hugo. This was later fixed in Hugo 0.149.0.

    This release reintroduces the performance optimization and will cause your page build to fail with the above mentioned Hugo versions. You either need to upgrade or downgrade Hugo to an unaffected version.

Breaking

  • Breaking The children shortcode has a new layout resembling the taxonomy and term pages by setting type=group.

    Sadly, introducing usage of the shortcode in the taxonomy and term pages (see below) caused necessary breaking changes

    • the shortcode now requires enabling block attributes in your hugo.toml by setting markup.goldmark.parser.attribute.block=true
    • the call syntax for type=card now is {{< children >}} instead of {{% children %}} if goldmark.unsafe=false is configured in your hugo.toml (which is the default)

    In addition the shortcode learned some new parameter for displaying breadcrumbs and setting a heading depth.

Change

  • Change This release comes with a new way to configure your logo image and title in the menu sidebar.

    With the new system you can

    • rely on auto detection for an image
    • remove the image completely
    • override the image for each variant
    • set color, sizes and fonts for title and image
    • let the image and title lay out vertically or horizontally
    • override the complete layout with your own partial (that’s the old way and still works)

    Nevertheless, this required massive changes to the CSS and most likely your logo will require tweaking of the CSS styles after an update.

    The easiest way to fix this is to remove a overridden layouts/partials/logo.html template in your installation and rely on the new configuration.

  • Change Font Awesome was updated to version 7.1.0 which results in slightly different icons.

  • Change The search results of the search box are now colored in the same way as the search results on the dedicated search page using color styles of the content area.

  • Change The expand shortcode has changed its default text of Expand me... to Details to be in sync with Hugo’s built-in details shortcode and the details HTML element.

New

  • New The taxonomy and term pages are now internally using the children shortcode. This makes it possible for you to set parameter of the children shortcode in your taxonomy/term pages front matter to change the layout.

    By that you can - for example - display the sub pages in a card layout. See the categories taxonomy for an example.

  • New The themes dark-mode support for the openapi shortcode was changed to the built-in implementation of the used Swagger library.
