Mar 17, 2020 8:45:39 PM / by Ivan Zhmud

python3-stable

I’m here to announce that today we are migrating our codebase to Python 3. Earlier, we announced Python 3 migration for Beta and there are some changes compared with the Beta release, namely, we have decided to keep the former name for the alt-python27-cllib package to provide backward compatibility and proper downgrade.

And now, all packages related to this release are scheduled for gradual rollout from our production repository and will be available for all customers within three weeks.

Rollout slot for CloudLinux 6/ 6 hybrid /7: 1

Rollout slot for CloudLinux 8: 2

Rolled out to: 1%

ETA for 100% rollout: March, 31st
