Upgrading Major Versions and Breaking Changes


The cookie format has been changed to be more compact. If you use the same Amplitude project(API key) across multiple applications, and you track anonymous users across those applications, you will want to update amplitude across all those applications at the same time. Otherwise these anonymous users will have a different device id in your different applications.

If you do not have multiple installations of amplitude, or if you do not track anonymous users across different installations of amplitude, this change should not affect you.
