Here we have the first beta release. We're not planning on making API changes anymore, but please be aware that there was one change from the previous release (alpha4). When running with Aegir SaaS, the nid argument has been renamed to target. Everything else is the same (API-wise). See #2724403: Replace POST argument name "nid" with "target" for details.
And we are finally here! Weeks have gone by without major bug reports and there is a small issue that has popped up regarding the progress bar but nothing that should stop you from picking out your typography!
Quiz 5 is a large update with lots of new functionality and architectural changes. It reflects over 2 years of development and testing and brings the Quiz project up to date with many of Drupal's built-in technologies, and sets a good starting point for a D8 version.
For the full feature list, and upgrade instructions, see the project page.
Quiz 7.x-4.x will only receive critical bug or security fixes.
