Login as the Super User in Piwik, go to Administration > General Settings. Next to “When checking for new version of Piwik, always get”, select “The latest beta release”. Click Save at the bottom of the page. You are now using the beta release channel!
If you want to update to the latest beta version, go to Administration, then click on the “Check for updates” box in the top right of the screen. In this box, click “Check for updates”. If a new beta is available, the “About Piwik” box will turn orange. You can then update Piwik in one click.
We do only release beta versions that are supposed to be stable (when our thousands of automated tests were successful), but please note that beta versions have a risk of containing bugs (which in some very rare cases could lead to data loss). If you find and report a bug in a beta version, we will aim to fix it as quickly as possible.
Thank you so much for using the beta channel!
