v9.0

In this release, the default theme has been almost completely rewritten, to improve accesibility, modernise the code, and remove unneeded libraries.

The loading mechanism has also been rewritten, so it's now possible to use a single copy of the Numbas runtime to load several questions or exams in a single page.

There are several breaking changes in this version and the minimum supported browser versions have changed.

There's more information about what's changed on the Numbas blog.
