Matomo 0.5

The Piwik development team is releasing Piwik 0.5 to address issues with performance, PHP 5.3.1 compatibility, and a potential security vulnerability in earlier versions of Piwik. We strongly encourage all Piwik users to update. In addition, users will also benefit from new features and bug fixes in this release.

Automated update
The automated update was inadvertently broken in 0.4.4 and 0.4.5. If you are running either of these versions, please update manually to 0.5 (see How to update Piwik manually?), preferably by installing Piwik in a fresh folder. Our apologies for the inconvenience.

Security
In disclosing this security risk, we urge all Piwik users to update to this release as soon as possible. If you are unable to update at this time, you should make the following changes immediately to secure your Piwik installation:

  • In « core/Cookie.php« , apply this patch
  • Remove the third-party file « libs/open-flash-chart/php-ofc-library/ofc_upload_image.php » (if it exists). (Reference: SA37078 advisory)

A special thanks to security researcher, Stefan Esser of SektionEins, for his assistance.

New report

This release adds a new report to « Actions | Pages » which displays the page Title.  There are now two page reports, Page URLs and Page Titles. The page title can be set via setDocumentTitle(). (Refer to Piwik’s JavaScript tracking API for more info.) In addition, this release addresses a significant table index bottleneck experienced by the largest Piwik instances. As a result of this performance enhancement, this release contains a schema update. If you have a large Piwik database, updates might take too long to run in the browser. If this situation applies to you, you can execute the updates from the shell (command line), e.g.,: $ php path/to/piwik/index.php.

Live! plugin

The « alpha » version of the « Live! » visitor plugin has also been updated, thanks to jr-ewing. To activate this plugin, go to « Settings | Plugins » and click on the « Activate » link. This will allow you to add a live visitor widget to the dashboard, and access the « Visitor Log » report from the menu. Please test-drive this plugin and provide feedback on the forum for further improvement. This is a beta release only.
