Distribution Details

For details on the distributions see each release page. For the supported platforms and versions of common dependencies and other considerations, see the official ROS 2 Target Platforms REP 2000.

未來散佈版

For details on upcoming features see the roadmap.

Currently there is a new ROS 2 distribution roughly every 6 months. The following information is a best estimate and is subject to change.

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

滾動散佈版

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 散佈版列表 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.
