  What’s new in Piwik 2.10.0 ?

  Since our last release Piwik 2.9.1 one month ago, over 100 issues have been closed. We’ve focused on fixing bugs, improving performance, and we created a new plugin that will let you better scale Piwik to very high traffic websites using Redis.

  Much improved Log Analytics

  Log Analytics is the powerful little-known feature of Piwik that lets you import dozens of different server logs into Piwik. In Piwik 2.10.0 you can now import Netscaler logs, IIS Advanced Logging Module logs, W3C extended logs and AWS CloudFront logs. Piwik will also automatically track the username as the User ID and/or the Page Generation Time when it is found in the server logs.

  Better scalability using Redis (advanced users)

  At Piwik PRO we are working on making Piwik scale when tracking millions of requests per month. In this release we have revamped the Tracking API. By using the new QueuedTracking plugin you can now queue tracking requests in a Redis database, which lets you scale the Piwik tracking service. The plugin is included as Free/libre software in the core Piwik platform. More information in the QueuedTracking user guide.

  Better performance

  A few performance challenges have been fixed in this release.

  The Visitor Log and the Live API will render much faster on very high traffic websites. Any custom date ranges that you have selected as default in your User Settings (eg. ‘Last 7 days’ or ‘Previous 30 days’) will now be pre-processed so that your analytics dashboard will always load quickly.

  For users on shared hosting, the real time widgets could be use a lot of server resource as they are refreshed every ten seconds. We’ve improved this by only requesting data when the Browser Tab containing the Real time widgets is active.

  Other changes

  We packed in many other changes in this release such as compatibility with Mysql 5.6 and Geo location support for IPv6 addresses. A community member made Piwik compatible with Internet Explorer 9 when running in compatibility mode (which is still used in several companies).

  The Tracker algorithm has been updated : when an existing visit uses a new Campaign then it will force creating a new visit (same behavior as Google Analytics).

  If you need professional support or guidance, get in touch with Piwik PRO.

  Changelog for Piwik 2.10.0 – we plan to release Piwik 2.10.0 around 2015 Jan 5th.

  Happy Analytics, and we wish you a nice holiday season !
