v0.1.1-alpha.19

@backstage/backend-common

• Allow listen host and port to be configured separately, in order to support PORT environment variables. #1950

@backstage/core

• Added new DiscoveryApi for discovering backend endpoint in the frontend, and use in most plugins. See packages/app/src/apis.ts for how to register in your app. #2074

@backstage/create-app

• Added catalog and scaffolder frontend plugins to the template along with the sidebar. #1942, #2084
• Many plugins have been added to the catalog and will for now be required to be added to separate apps as well. This will be solved as #1536 gets sorted out, but for now you may need to install some plugins just to get pages to work.

@backstage/catalog-backend

• Added the possibility to add static locations via app-config.yaml. This changed the signature of new LocationReaders(logger) inside packages/backend/src/plugins/catalog.ts to new LocationReaders({config, logger}). #1890

@backstage/theme

• Changed the type signature of the palette, removing sidebar: string and adding navigation: { background: string; indicator: string}. #1880
