v21.0.0

21.0.0 (2025-11-22)

As always we recommend that you update your existing workspaces by using ng update as we provide some helpful schematics to help migrate your workspaces to the latest and greatest. Running the following will update Angular, the Angular CLI and angular-eslint together:

ng update @angular/core @angular/cli angular-eslint

🚀 Features

• ⚠️ update Angular dependencies to v21 (6a6b671e)
• ⚠️ eslint-plugin: formally deprecate [no-conflicting-lifecycle] and remove from "all" config (5d845924)
• ⚠️ eslint-plugin-template: add prefer-control-flow to recommended config (77cd24d3)
• ⚠️ eslint-plugin-template: add textContent to default allowList (f112c169)
• schematics: generate new projects using eslint defineConfig (5aa8171b)

🩹 Fixes

• ⚠️ builder: align formatter invocation with eslint CLI by always passing all files, even if quiet (bceaa80e)
• ⚠️ eslint-plugin: make component-selector and directive-selector configurations strict and clear (938362cb)

⚠️ Breaking Changes

• eslint-plugin: formally deprecate [no-conflicting-lifecycle] and remove from "all" config (5d845924)
• eslint-plugin-template: add textContent to default allowList (f112c169)
• builder: align formatter invocation with eslint CLI by always passing all files, even if quiet (bceaa80e)
• eslint-plugin: make component-selector and directive-selector configurations strict and clear (938362cb) The selector validation logic has been updated to be more strict and predictable: Default Prefix Change:
  • Both component-selector and directive-selector now default to prefix: 'app' to match Angular CLI defaults
  • This means selectors without the 'app' prefix will now fail validation unless a different prefix is explicitly configured Style and Prefix Validation Changes:
  • Single-word selectors (e.g., 'appselector') are now appropriately considered valid for both camelCase and kebab-case styles
