Django 2.2
What is this?
Most of our production services had been using Django 1.11, a long-term support release which reached end of life in April 2020. We switched them to use Django 2.2, the next LTS release which is supported until April 2022.
What do I do?
Report any remaining usage of Django < 2.2 you find to the arch-bom team.
Where are we now?
Essentially all of our services are now upgraded.
Mongo 3.6
Joe Mulloy (Deactivated) and the DevOps team upgraded Mongo to 3.6 in March 2020.
Where are we now?
We are using Mongo 3.6 and hosting our own databases, in the future we may want to upgrade to Mongo 4 and use AWS DocumentDB
Python 3.5
What is this?
Most of our production services were using Python 2.7, which reached end of life in January 2020.
What do I do?
Report any remaining usage of Python 2 you find to the arch-bom team.
Where are we now?
Essentially all services are now on some still-supported version of Python 3. One or two stragglers are in the process of being deprecated and shut down, and the last remaining usage of 2.7 in the configuration repo for deployments is being cleaned up.
