Target platforms for future releases are speculative and are based on
consulting Ubuntu's release and end-of-life schedule [1]_.

The approximate formula for choosing target platforms is:
The following rules are used for choosing the target platforms. They
aim to limit the number of supported Ubuntu version for each ROS
distribution to a small number (<= 3) as well as provide a reasonable
upgrade path for users as well as maintainers of packages.

1st after LTS, e.g. C Turtle:
LTS +/- 1
* The latest Ubuntu version (released around the same time as the ROS
distribution).

2nd after LTS, e.g. Diamondback:
LTS +2
* The current Ubuntu LTS version.

3rd after LTS, e.g. Electric:
LTS +3
* The previous Ubuntu version.

4th after LTS, 1st before next LTS:
Rebase: target platforms selected to enable migration to next LTS
* At least one Ubuntu version which is common with the two previous
ROS distributions.

Any "formula" requires making assumptions about future Ubuntu library
choices and other crystal-ball projections. While we will do our best

Our intent with Python support is to track the minimum Python version
provided in the supported Ubuntu platforms, as well as survey other

While we still support Ubuntu versions which ship with Python 2 by default
all Python scripts should provide dual compatibility with Python
2.7+ and Python 3.3+.
