Distributions

What is a Distribution?

A ROS distribution is a versioned set of ROS packages. These are akin to Linux distributions (e.g. Ubuntu). The purpose of the ROS distributions is to let developers work against a relatively stable codebase until they are ready to roll everything forward. Therefore once a distribution is released, we try to limit changes to bug fixes and non-breaking improvements for the core packages (every thing under ros-desktop-full). That generally applies to the whole community, but for «higher» level packages, the rules are less strict, and so it falls to the maintainers of a given package to avoid breaking changes.

The expectation is to release new ROS 2 distributions once per year.

Rolling Distribution

The Rolling distribution of ROS 2 serves as a staging area for future stable distributions of ROS 2 and as a collection of the most recent development releases. Unlike most stable ROS 2 distributions which have an initial release, a support window during which they are updated, and a definite end of support (see List of Distributions above) the Rolling distribution is continuously updated and is subject to in-place updates which will at times include breaking changes.

Packages released into the Rolling distribution will be automatically released into future stable distributions of ROS 2. Releasing a ROS 2 package into the Rolling distribution follows the same procedures as all other ROS 2 distributions.

ROS 2 Rolling Ridley is the rolling development distribution of ROS 2 as proposed in REP 2002. It was first introduced in June 2020.

The Rolling distribution will receive frequent and possibly compatibility-breaking releases in core packages and we recommend most people use the most recent stable distribution instead. Since new stable distributions will be created from snapshots of the Rolling distribution, package maintainers who want to make their packages available in future ROS 2 distributions can do so by releasing their packages into the Rolling distribution.
