This patch disables `track` (aka `science`) endpoint, firebase tracking, fabric.io tracking and crashlytics.
As of 8.3.5g, it also removes various fields from `superProperties` that could be used to track your device. This was planned to be added all the way back in 8.3.2, but I apparently forgot to commit it. Bleh. Also as of 8.3.5, adjust and ganalytics are blocked as well. That should be all.
