Would it be more correct to say that **colcon** has been selected as build tool now for ROS2 and ROS1
[/quote]

No,not for both ROS versions. We only recommend `colcon` for ROS 2 at the moment.

the previously used **cakin_tools** build tool only for ROS1
[/quote]

For ROS 1 we still recommend using `catkin_make` / `catkin_make_isolated` (`catkin_tools` is also not the recommended tool even though many users are successfully using it), 

[quote="miguel_angel_rodrigu, post:3, topic:7319"]
And that where users in ROS1 one previously used **catkin_make** command now will use the **colcon build** command?
[/quote]

The following ticket contains some more context why we don't recommend using `colcon` for ROS 1 even though it should be perfectly able to do the job (and offer many more features than the currently recommeded tool): https://github.com/colcon/colcon-core/issues/149
