 ## Unreleased
 
+* Add option to track GCLID (Google Click ID) as a user property (set `includeGclid` to `true` in the SDK configuration).
+* Add option to track new UTM parameters, referrer, and GCLID values during the same session. By default the SDK only saves the values once at the start of the session. You can remove this restriction by setting `saveParamsReferrerOncePerSession` to `false` in the SDK configuration. See the [Readme](https://github.com/amplitude/Amplitude-Javascript#tracking-utm-parameters-referrer-and-gclid) for more information.
+
 ### 3.2.0 (October 7, 2016)
 
 * Block event property and user property dictionaries that have more than 1000 items. This is to block properties that are set unintentionally (for example in a loop). A single call to `logEvent` should not have more than 1000 event properties. Similarly a single call to `setUserProperties` should not have more than 1000 user properties.

 # Advanced #
 This SDK automatically grabs useful data about the browser, including browser type and operating system version.
 
+### Tracking UTM Parameters, Referrer, and GCLID ###
+
+Amplitude supports automatically tracking:
+  * Standard UTM parameters from the user's cookie or URL parameters, just set configuration option `includeUtm` to `true` during initialization.
+  * The referring URL, just set configuration option `includeReferrer` to `true` during initialization.
+  * GCLID (Google Click ID) from URL params, just set configuration option `includeGclid` to `true` during initialization.
+
+If tracking is enabled, then the SDK will set the values as user properties, for example `referrer` or `utm_source`, once per session (this is last touch). The SDK will also save the initial values using a `setOnce` operation, for example `initial_referrer` or `initial_utm_source`, and once set that value will never change (this is first touch).
+
+**Note:** By default the SDK will only save the values at the start of the session. For example if a user lands on your site with an initial set of UTM parameters, triggers some flow that causes them to land on your site again with a different set of UTM parameters within the same Amplitude session, that second set will not be saved. You can set configuration option `saveParamsReferrerOncePerSession` to `false` to remove that restriction, so the SDK will always capture any new values from the user.
+
 ### Setting Groups ###
 
 Amplitude supports assigning users to groups, and performing queries such as Count by Distinct on those groups. An example would be if you want to group your users based on what organization they are in by using an orgId. You can designate Joe to be in orgId 10, while Sue is in orgId 15. When performing an event segmentation query, you can then select Count by Distinct orgIds to query the number of different orgIds that have performed a specific event. As long as at least one member of that group has performed the specific event, that group will be included in the count. See our help article on [Count By Distinct](https://amplitude.zendesk.com/hc/en-us/articles/218824237) for more information.
