• The old bullet point is still present (and using -- instead of -) which duplicates the updated line below. Remove this outdated entry to avoid confusion.

-- `version` (optional) - the version to test the uuid for. Supported version are `3`, `4` and `5`. Defaults to test for `all` three if omitted.

test/asserts/uuid-assert.test.js:73

• Consider adding negative test cases for the new v7, nil, and max UUID formats to verify that invalid strings are correctly rejected.
