This is a changelog for Piwik platform developers. All changes for our HTTP API's, Plugins, Themes, etc will be listed here.
## Piwik 2.10.0
### New APIs
* New URL parameter `send_image=0` in the [HTTP Tracking API](http://developer.piwik.org/api-reference/tracking-api) to receive a HTTP 204 response code instead of a GIF image. This improves performance and can fix errors if images are not allowed to be obtained directly (eg Chrome Apps).
