This document shows you what’s new in the latest release. For a detailed list of changes, see the history page.
Breaking: A change that requires action by you after upgrading to assure the site is still functional.
Change: A change in default behavior. This may requires action by you / may or may not be revertable by configuration.
New: Marks new behavior you might find interesting or comes configurable.
Breaking: We made changes to the menu footer. If you have your
menu-footer.htmlpartial overridden, you may have to provide additional styling in your partial. For a reference take a look into the
menu-footer.htmlpartial that is coming with the exampleSite.
This change was made to allow your own menu footer to be placed right after the so called prefooter that comes with the theme (containing the language switch and Clear history functionality).
Breaking: We have changed the default colors from the original Learn theme (the purple menu header) to the Relearn defaults (the light greem menu header) as used in the official documentation.
This change will only affect your installation if you’ve not set the
themeVariantparameter in your
config.toml. If you still want to use the Learn color variant, you have to explicitly set
Note, that this will also affect your site if viewed with Internet Explorer 11 and can not be reconfigured as it does not support CSS variables.
Change: Due to a bug, that we couldn’t fix in a general manner for color variants, we decided to remove
New: With this release you are now capable to define your own dark mode variants.
To make this possible, we have introduced a lot more color variables you can use in your color variants. Your old variants will still work and don’t need to be changed as apropriate fallback values are used by the theme. Nevertheless, the new colors allow for much more customization.
To see what’s now possible, see the new variants
neonthat are coming with this release.
New: You can now configure multiple color variants in your
config.toml. In this case, the first variant is the default chosen on first view and a theme switch will be shown in the menu footer. See the documentation for configuration.
Note, that the new theme switch will not work with Internet Explorer 11 as it does not support CSS variables.
Breaking: This release removes the themes implementation of
relrefin favor for Hugos standard implementation. This is because of inconsistencies with the themes implementation. In advantage, your project becomes standard complient and exchanging this theme in your project to some other theme will be effortless.
In a standard complient form you must not link to the
*.mdfile but to its logical name. You’ll see, referencing other pages becomes much easier. All three types result in the same reference:
Type Non-Standard Standard Branch bundle
If you’ve linked from a page of one language to a page of another language, conversion is a bit more difficult but Hugo got you covered as well.
Also, the old themes implementation allowed refs to non-existing content. This will cause Hugos implementation to show the error below and abort the generation. If your project relies on this old behavior, you can reconfigure the error handling of Hugos implementation.
In the best case your usage of the old implementation is already standard complient and you don’t need to change anything. You’ll notice this very easily once you’ve started
hugo serverafter an upgrade and no errors are written to the console.
You may see errors on the console after the update in the form:
ERROR 2021/11/19 22:29:10 [en] REF_NOT_FOUND: Ref "basics/configuration/_index.md": "hugo-theme-relearn\exampleSite\content\_index.en.md:19:22": page not found
In this case, you must apply one of two options:
Copy the old implementation files
theme/hugo-theme-relearn/layouts/shortcode/relref.htmlto your own projects
layouts/shortcode/relref.htmlrespectively. This is not recommended as your project will still rely on non-standard behavior afterwards.
Start up a text editor with regular expression support for search and replace. Apply the following conversions in the given order on all
*.mdfiles. This is the recommended choice.
Type Search Replace by Branch bundle
Change: Although never officially documented, this release removes the font
Novecento. If you use it in an overwritten CSS please replace it with
Work Sans. This change was necessary as Novacento did not provide all Latin special characters and lead to mixed styled character text eg. for czech.
New: The theme now supports favicons served from
logoin SVG, PNG or ICO format out of the box. An overridden partial
layouts/partials/favicon.htmlmay not be necessary anymore in most cases.
New: You can hide the table of contents menu for the whole site by setting the
disableTocoption in your
config.toml. For an example see the example configuration.
- New: Optional second parameter for
noticeshortcode to set title in box header.
- New: Your site can now be served from a subfolder if you set
config.toml. See the documentation for a detailed example.
- Change: New colors
--CODE-BLOCK-BG-colorwere added to provide a fallback for Hugos syntax highlightning in case
guessSyntax=trueis set. Ideally the colors are set to the same values as the ones from your chosen chroma style.
Change: Creation of customized stylesheets was simplified down to only contain the CSS variables. Everything else can and should be deleted from your custom stylesheet to assure everything works fine. For the predefined stylesheet variants, this change is already included. The documentation was adjusted accordingly.
New: Hidden pages are displayed by default in their according tags page. You can now turn off this behavior by setting
New: You can define the expansion state of your menus for the whole site by setting the
alwaysopenoption in your
config.toml. Please see further documentation for possible values and default behavior.
New: New frontmatter

childrenshortcode. Possible values are
New: Alternate content of a page is now advertised in the HTML meta tags. See Hugo documentation.
- New: Hidden pages are displayed by default in the sitemap generated by Hugo and are therefore visible for search engine indexing. You can now turn off this behavior by setting
Change: In case the site’s structure contains addional *.md files not part of the site (eg files that are meant to be included by site pages - see
CHANGELOG.mdin the exampleSite), they will now be ignored by the search.
New: Hidden pages are indexed for the site search by default. You can now turn off this behavior by setting
New: If a search term is found in an
expandshortcode, the expand will be opened.
New: The menu will scroll the active item into view on load.
Change: Syntaxhighlightning was switched to the built in Hugo mechanism. You may need to configure a new stylesheet or decide to roll you own as described on in the Hugo documentation
Change: In the predefined stylesheets there was a typo and
--MENU-HOME-LINK-HOVERED-colormust be changed to
--MENU-HOME-LINK-HOVER-colorwere missing in the documentation. You should add them to your custom stylesheets.
Change: Arrow navigation and
childrenshortcode were ignoring setting for
ordersectionsby. This is now changed and may result in different sorting order of your sub pages.
Change: If hidden pages are accessed directly by typing their URL, they will be exposed in the menu.
Change: A page without a
titlewill be treated as
