To meet Google's August 2019 deadline requiring 64-bit apps in the Google Play Store, we must ship ARM64 Fennec to the Release channel no later than Fennec 68 (2019-07-09). Thus, ARM64 Fennec will need to ride the trains no later than Fennec 68 Beta (2019-05-13).

- Fennec 67 Nightly's top crashes for ARMv7 vs ARM64
M1: ARM64 Baseline Nightly
Publish ARM64 Fennec and GeckoView Nightly builds in the Google Play Store with ARM64 Baseline (but not Ion). We don't want these ARM64 Baseline-only ride to Beta or Release, but getting ARM64 Baseline stable is a prerequisite for ARM64 Ion and we'd like to get some dogfood testing of ARM64 builds. We need to fix all ARM64 Baseline JIT test failures before publishing ARM64 Fennec and GeckoView Nightly builds in the Google Play Store.
Bugs with the [arm64:m1] whiteboard tag:

M2: ARM64 Ion Nightly
Enable ARM64 Ion in Fennec and GeckoView Nightly builds. We need to fix all ARM64 Ion JIT test failures before enabling Ion for ARM64 Fennec and GeckoView Nightly users.
Bugs with the [arm64:m2] whiteboard tag:
No results.
0 Total; 0 Open (0%); 0 Resolved (0%); 0 Verified (0%);
M3: ARM64 Ion Beta
Let ARM64 Ion in Fennec and GeckoView ride to Beta and Release. We should fix as many Nightly crash reports and fuzz bugs as time permits before letting Ion ride the trains.
To meet Google's deadline, ARM64 Fennec will need to ride the trains no later than Fennec 68 Beta (2019-05-13).
