Keeping up to date with an integration like ZiLink is critical to the performance of both Moodle and ZiLink. New features and fixes are produced regularly and so it pays to make sure that you're on the latest version.
So how do you receive notification of a new release?
The first thing to do is make sure that your Moodle version is supported by ZiLink. We always recommend that you should be using the latest stable version of Moodle or at least a stable version that is supported by Moodle.org for serious security patches. If you're unsure you can check our Knowledge Base at http://support.schoolsict.net/entries/25047303-Supported-Moodle-Installations.
Please refer to this page for information about configuring Moodle for your version. This link is for Moodle 2.7 http://docs.moodle.org/27/en/Automatic_updates_deployment. Potential issues regarding the updating process are also documented on that page.
SchoolsICT will publish all updates for ZiLink through this process.
Updates for ZiNET Connect will automatically occur through the existing process, ZiNET Pulse.
