 Most previous deployments of the Amplitude Segment destination used the device-mode connection to use the `session_id` tracking feature. The new Actions-framework Amplitude destination, includes session ID tracking by default. When connected to the Analytics.js 2.0 source, Segment automatically loads a plugin on your website for session tracking and enrichment as an alternative to the Amplitude SDK.

It also means that you can use more of the Segment platform features on data going to Amplitude, such as Protocols filtering and transformations, and Profiles Identity Resolution.
