These are the release notes for the v1.16.0 release of Backstage.

A huge thanks to the whole team of maintainers and contributors as well as the amazing Backstage Community for their hard work in getting this release developed and done. A little smaller release this time with the Summer Holidays, hope you’re all having some deserved time off also!


Continued support for Material-UI V5

There have been some more tweaks here or there to types and the theme system to ensure a smooth future migration toward Material-UI version 5.

BREAKING: @backstage/plugin-catalog-backend-module-incremental-ingestion

Incremental event handlers are now async by default, and their response shape has been changed to allow further extension.

Instead of returning null or undefined from an event handler to indicate no-oop, instead return the value { type: "ignored" }.

The configuration has been changed and the authentication property of confluence.auth is now an object instead to allow further evolution.
