- {{% badge style="note" title=" " %}}Change{{% /badge %}} The way you [link to pages in a different language](configuration/content/linking#cross-language-links) has changed. Until now this was an undocumented feature.
Previously you could prepend an URL with the language code, e.g. `/pir/my-page` to link to pages of other languages. This could cause problems if you have a page with the same name as the language code on the top level of your page structure.
Now you have to set the query parameter `lang` to the language code, e.g. `/my-page?lang=pir`.
As this was previously undocumented, most projects will not be affected. If you still need the old behavior, you can set `enableLegacyLanguageLinks=true` in your `hugo.toml`.
- {{% badge style="note" title=" " %}}Change{{% /badge %}} The `target` parameter of the [`button` shortcode](shortcodes/button#parameter) was deprecated.
Use [link effects](authoring/markdown#link-effects) on the `href` parameter instead. You don't need to change anything as the old parameter still works but may generate warnings.
- {{% badge style="info" icon="plus-circle" title=" " %}}New{{% /badge %}} The theme now allows page references (given as `pageRef` of a [Hugo menu item](https://gohugo.io/content-management/menus/), `pageRef` parameter of a [`sidebarmenus` entry ](configuration/sidebar/menus#defining-sidebar-menus) and the `menuPageRef` in a [page's front matter](configuration/sidebar/menus/#displaying-arbitrary-links-in-a-page-menu)) to also be global resources from your `assets` directory.
- {{% badge style="info" icon="plus-circle" title=" " %}}New{{% /badge %}} If [`link.errorlevel` is configured](authoring/frontmatter/linking/#enabling-link-and-image-link-warnings), now also page references will be checked for existence.
- {{% badge style="info" icon="plus-circle" title=" " %}}New{{% /badge %}} It is now possible to add query parameter and an optional fragment part to all links. This is regardless whether it is a local or remote address and also applies to Hugo's internal path.
- {{% badge style="info" icon="plus-circle" title=" " %}}New{{% /badge %}} This release introduces [link effects](authoring/linkeffects) which work similar to [image effects](authoring/imageeffects) and can be set as query parameter on any link.
- that a link should result in a file download in your browser
- {{% badge style="info" icon="plus-circle" title=" " %}}New{{% /badge %}} You can now [configure an ignore list](authoring/frontmatter/linking/#ignoring-false-negatives) of addresses that should be ignored if an errorlevel test fails. This is configured by setting `errorignore=[]` globally in your `hugo.toml` for all errorlevel checks.
This helps to remove false negatives while still benefitting from the check for all other addresses.
- {{% badge style="info" icon="plus-circle" title=" " %}}New{{% /badge %}} The theme supports the new [`source` output format](configuration/sitemanagement/outputformats/#source-support) which behaves similar in configuration as the `markdown` output format but allows the original Markdown source including the front matter of a page to be viewed.
You can see this in action on the above linked page, accessible by clicking the {{% button style="transparent" icon="file-code" %}}{{% /button %}} topbar button.
- {{% badge style="info" icon="plus-circle" title=" " %}}New{{% /badge %}} If you haven't overridden `layouts/partials/custom-header.html` and `css/custom.css` and/or `js/custom.js` is present in your project, the theme now adds them to your pages.
This was done to be compatible with adding custom scripts in an older version of the Hugo documentation.
