...

• Ruby 2.x
• ElasticSearch will be upgraded, probably to 1.5 which is what we use in production.  This will coincide with changes to the forums service to support the newer version.
  • In addition to migration documentation, we should remind about "rake search:initialize" and "rake search:validate_index".
• Credentials Service
  • The service now requires Python 3.5
• E-Commerce Service
  • Django Oscar has been upgraded to 1.4. (The steps below only apply to existing installations, and can be ignored for new installations.)
    • This upgrade requires faking migrations for the thumbnail app: ./manage.py migrate thumbnail --fake

    • Site maintainers should be aware that one of the migrations includes a change on the guest_email column in the orders table. If your orders table is large 1M+ rows, this migration may lock the table for an extended amount of time. The E-Commerce Service does not normally use the guest_email column. If you have not modified your system to use this column, and wish to avoid the table lock, it is recommended that you fake this migration:
      ./manage.py migrate orders 0012

      ./manage.py migrate orders 0013 --fake

• Will devtack be docker based, or will we still need vagrant?
• Will native/fullstack require docker?
• Will catalog service be required?
• Are there required upgrades for Django, pip, ...
• Will there be a significant change to the asset pipeline in time for Ginkgo? (Probably not but something to keep an eye on) 
• Upgrade to RabbitMQ https://github.com/edx/configuration/pull/3297
  • 3.2.1 → 3.6.9 
  • Upgrading in place on devstacks may be fine (it appears rabbit will upgrade structures on disk when it starts back up)
  • Upgrading a cluster is more fun depending on downtime options https://www.rabbitmq.com/clustering.html 
  • We're using https://www.rabbitmq.com/shovel.html
