As a person interested in having the most stable builds possible, I would like to control the contents of the build container more than I currently can.
- As you update the build containers, give a unique version to each new image.
- Allow me to specify in the circle.yml file which version I want to build with, eg. ‘Trusty 2016.3’
- Offer a generic version like ‘Trusty’ meaning ‘the youngest image in the Trusty line’.
