New features

The Royal Arms has been updated

The Royal Arms in the GOV.UK footer has been updated to reflect the version introduced by King Charles III.

If your service does not use the image directly from the Frontend package, you should ensure the new image is being copied to your service’s image assets folder. By default this folder is located at /assets/images.

If you’re using Nunjucks, the asset path may have been changed by the assetPath global variable or assetsPath parameter on the header component.

Copy the govuk-crest.svg file from /dist/assets/images into your assets folder.

You can safely delete the old image files, named govuk-crest.png and govuk-crest@2x.png.

We introduced this change in pull request #​5376: Update the Royal Arms graphic in footer (v5.x).

Components will not longer initialise twice on the same element

GOV.UK Frontend components now throw an error if they've already been initialised on the DOM Element they're receiving for initialisation.
This prevents components from being initialised more than once and therefore not working properly.

We introduced this change in pull request #​5272: Prevent multiple initialisations of a single component instance

Respond to initialisation errors when using createAll and initAll

We've added a new onError option for createAll and initAll that lets you respond to initialisation errors.
The functions will continue catching errors and initialising components further down the page if one component fails to initialise,
but this option will let you react to a component failing to initialise. For example, to allow reporting to an error monitoring service.

We introduced this change in:

• pull request #​5252: Add onError to createAll
• pull request #​5276: Add onError to initAll

Check if GOV.UK Frontend is supported

We've added the isSupported function to let you check if GOV.UK Frontend is supported in the browser running your script.
GOV.UK Frontend components check this automatically, but you may want to use the isSupported function to avoid running some code when GOV.UK Frontend is not supported.

We introduced this change in pull request #​5250: Add isSupported to all.mjs

Use our base component to build your own components

We've added a Component class to help you build your own components. It allows you to focus on your components' specific features by handling these shared behaviours across components:

• checking that GOV.UK Frontend is supported
• checking that the component is not already initialised on its root element
• checking the type of the root element and storing it for access within the component as this.$root

We introduced this change in:

• pull request #​5350: Export a base Component class.
• pull request #​5354: Refactor the root type check in GOVUKFrontendComponent

New brand colour

We've added a brand colour for the Serious Fraud Office in pull request #​5389.
