21.0.0 (2025-11-22)

🚀 Features

• ⚠️ eslint-plugin-template: add textContent to default allowList (f112c169)
• ⚠️ eslint-plugin-template: add prefer-control-flow to recommended config (77cd24d3)

🩹 Fixes

• ⚠️ eslint-plugin: make component-selector and directive-selector configurations strict and clear (938362cb)

⚠️ Breaking Changes

• ⚠️ eslint-plugin-template: add textContent to default allowList (f112c169)
• 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
  • Style validation is now completely independent from prefix validation
  • When a prefix is defined and found in a selector, the rule now correctly validates whether the prefix is properly separated according to the style:
    • For kebab-case: prefix must be followed by a hyphen (e.g., 'app-selector' ✓, 'appselector' ✗)
    • For camelCase: prefix must be followed by an uppercase letter (e.g., 'appSelector' ✓, 'appselector' ✗) Changes to error reporting:
  • Selectors that have valid style but improper prefix usage now report 'prefixFailure' instead of 'styleAndPrefixFailure'
