Back in 2017, we released D8, a new faster dexing compiler to replace DX, producing smaller APKs. In April 2018, we announced D8 as the default option in Android Studio 3.1.
In that announcement, we laid out 3 phases to deprecate DX and we are now entering phase 2:
“Once we've seen a six month window without major regressions from DX to D8, we'll enter the second phase. This phase will last for a year, and is intended to ensure that even complex projects have lots of time to migrate. During this phase, we'll keep DX available, but we'll treat it as fully deprecated; we won't be fixing any issues.”
On Feb 1st, 2021, we’ll move to step 3, removing DX fully from Android Studio and any other build environments.
Note: This post is about DX only (and does not include shrinking tools)
