v1.20.0

These are the release notes for the v1.20.0 release of Backstage.

A huge thanks to the whole team of maintainers and contributors as well as the amazing Backstage Community for the hard work in getting this release developed and done.

Highlights​

Support for experimental type build has been removed​

The --experimental-type-build option is no longer supported by any commands in the Backstage CLI. Existing usage should be migrated to using subpath exports instead.

Experimental support for Vite ⚡​

Due to some concerns about performance in larger monorepo setups and hot-reloading times, we’re looking to replace Webpack with Vite longer term, and in this release we’re shipping experimental support for Vite behind an EXPERIMENTAL_VITE environment variable flag when running yarn start in the frontend.

Please reach out by creating a GitHub issue with any problems that you might be running into when using this experimental feature.

Scaffolder: react-jsonschema-form@v5 + Design tweaks 💅​

It’s finally here. We’ve shipped support for react-jsonschema-form@v5 which should be a completely non-breaking change for end users. We’ve also tweaked some of the designs for some of the new Scaffolder Pages. You can read more in the relevant migration docs

Catalog Presentation API​

The Catalog plugin now uses the EntityPresentationApi to decide how entities are rendered in the UI. This includes fetching catalog data in the background in order to show entities using their metadata.title. For more information, including how to customize the presentation, see the PR, (documentation is in the works!).

Security Fixes​

This release does not contain any security fixes.
