Please note that on Wednesday 3rd April between 7am and 10am, moodle will be upgraded from the current 4.1.4 version to 4.1.9 and the STACK question plugin will be upgraded from the current 4.4.4 version to 4.4.6. These releases are all minor releases and will not result in any visual changes to the system, but they will apply security patches and fix some previously broken functionality. During part of this maintenance window the system will be unavailable to both students and teaching staff. We will aim to restore the service as soon as possible.
