6. STACK now has an [API](../Installation/API.md) to provide STACK questions as a web service.
7. Improve the display of floats. Numbers of decimal places are now respected in all parts of expressions, and floats such as `1.7E-9` are displayed at \(1.7 \times 10^{-9}\). There is a new question option to choose between \(1.7 \times 10^{-9}\) and \(1.7E-9\).

It's easier to create a question within Moodle and export XML than create a question within a test. The question then
needs to be converted into a format useable by the tests, however, and put in the helper.php file.
