+title: Analytics.js 2.0 (Beta)
+strat: ajs
+---
+Analytics.js is Segment's most popular library source. This new major version has been re-engineered to be more performant and provide greater extensibility. It is fully backwards compatible with the previous version of Analytics.js.
+
+## Benefits of Analytics.js 2.0
+
+The Analytics.js 2.0 Beta provides two key benefits over the previous version.
+
+### Performance
+
+Analytics.js 2.0 provides a reduction in page load time, which improves overall site performance. Its package size is **~70%** smaller than the previous Analytics.js.
+
+> info ""
+> There are many factors that impact page load time, including page weight, network conditions, and hosting locations.
+
+### Developer experience
+
+Analytics.js 2.0 introduces new ways for developers to augment events throughout the event timeline. This enables teams to support:
+
+- New privacy and consent controls before an event occurs
+- Enriching events with additional customer or page context in-flight using middleware
+- Collecting better metrics related to deliverability *after* a message is sent
+
+## Start using Analytics.js 2.0
+
+Analytics.js is released as a Public Beta, on an opt-in basis, *per source*. The updated code is delivered through your existing snippet, so there's no need to update code on your site.
+
+To opt in:
+
+1. Navigate to the **Settings** tab of the javascript source you want to enable.
+2. Enable the Analytics 2.0 toggle.
+
+Once enabled, after 5 minutes or less, the updated code is delivered.
+
+## Disable Analytics.js 2.0
+
+To revert back to the previous version of Analytics.js, disable the Analytics 2.0 toggle on any source you've enabled it.
