• CLI: Fix TAP compliance for early errors (e.g. syntax error in test file). 01f7780bd8
• Core: Add memory to late error event listeners, to improve reporting of early errors. 7c2f871ac3

2.24.0

FYI:

• 📗 There are new Guides, Support, and Chat sections on qunitjs.com. Including best practices and examples for async tests, callbacks, and event-based code.

Added

• CLI: Add .mjs and .cjs to the default file extensions when reading a test directory.

  These have been monitored by watch mode since QUnit 2.18, but were not loaded or executed unless you passed them as individual files, or used your own glob like test/*.{js,mjs,cjs}.

  If you currently pass a directory to the QUnit CLI and have matching .mjs or .cjs files that should not be executed, you can opt-out by passing test/*.js or test/**/*.js explicitly instead of test/.

• CLI: Add stacktrace cleaning by omitting or greying out internal QUnit and Node.js frames in TAP reporter. #1795. #1789
