1964445 - New Tab 140 has tight coupling to getEnrollmentMetadata, which only exists from 140 onwards

Status: RESOLVED WONTFIX

(Firefox :: New Tab Page, defect, P1)

Description

[Mike Conley (:mconley) (:⚙️)]

This API only got landed in https://hg-edge.mozilla.org/mozilla-central/rev/c2e89f5ddf10, which is in 140.

This prevents the 140 version of New Tab from train-hopping to Beta 139.

Attachment: Bug 1964445 - Make DiscoveryStreamFeed use both the old and new forms of talking to the Nimbus experiment metadata utility. r?beth!

This will allow us to train-hop the New Tab code from 140 (which uses the new form
of talking to NimbusFeatures.pocketNewtab.getEnrollmentMetadata()) to 139
(which does not yet have the getEnrollmentMetadata API).

We effectively feature-detect and fallback to the old mechanism here.
