Piwik 1.5 was released yesterday. The new version includes a fix for a security vulnerability that would allow Piwik installations that allow anonymous user access to reports, which they are not by default, to be “compromised using arbitrary code execution”. The new version also includes analytics for ecommerce, the replacement of flash based graphs, refined control over anonymization of visitor’s IP addresses, and bug fixes.
More information is available in the release announcement.
