Hi everyone, as some of you have noticed already, the preview004 of v14 with Bellissima is now out on MyGet on the "prereleases" feed. You can find and install it as always with nuget and the Umbraco.Templates package: https://docs.umbraco.com/umbraco-backoffice/getting-started/installing-preview-builds A few things have changed frontend-wise; since Vite is now by default using Lit 3 when installing its template presets, we had to add a

--force

parameter to our recommendations in the tutorials to ensure you can use Lit 3 while the backoffice itself still uses Lit 2. We are planning to upgrade to Lit 3 for the next preview release, but until then you can certainly build your own extensions with Lit 3. The tutorial for creating your first extension has been mended as a result of this: https://docs.umbraco.com/umbraco-backoffice/tutorials/creating-your-first-extension Also for general recommendations on using Vite as a bundler regardless of Lit, we have updated the "Vite Package Setup" article with the latest commands and configs: https://docs.umbraco.com/umbraco-backoffice/extending/development-flow/vite-package-setup Be aware that you will now find the

@umbraco-cms/backoffice

preview package on MyGet as well, unlike other previews which were released directly on npmjs.org. The tutorials and commands have been updated accordingly - the main difference is to specify the

--registry

when running the command, e.g.

npm install --force --registry https://www.myget.org/F/umbracoprereleases/npm/ -D @umbraco-cms/backoffice@14.0.0--preview004
