Announcement: RealSense ROS wrapper 4.55.1 now available

[MartyG-RealSense]

Hi everyone,

Version 4.55.1 of the RealSense ROS wrapper is now available.

https://github.com/IntelRealSense/realsense-ros/releases/tag/4.55.1

[tonynajjar]

It doesn't specify the "Supported RealSense SDK" and "Supported Devices", could you specify? Thanks

[MartyG-RealSense]

Typically, the naming of the wrapper reflects the librealsense version it is designed to work with. For example, wrapper 4.54.1 = SDK 2.54.1. So wrapper 4.55.1 will be for SDK 2.55.1.

The wrapper supports RealSense 400 Series cameras (such as D415, D435, D435i, D435f, D435if, D455, D455f, D456, D457). From SDK 2.55.1 onwards though, the L515 and SR300 camera models are no longer supported.

Thanks for the answer, this practically means that librealsense and realsense-ros always have to be upgraded together? It isn't possible e.g. to use librealsense 2.54.2 with realsenes-ros 4.55.1?

[MartyG-RealSense]

As a general rule, if a new SDK version only has a small number of changes from the previous version then you can risk using the new version with a wrapper meant for the previous one. For example, 2.54.2 was mostly bug-fixes rather than new features and so it still works with wrapper 4.54.1.

However, 2.55.1 has extensive feature and API changes and so a new wrapper designed specifically for it is the best choice.

Is it now availablevia apt-get install? Keeps giving me the 4.54 on Ubuntu 22.04 LTS jammy amd64

@jesusramondovale The wrapper repository lists the current package version as 2.55.1.

https://index.ros.org/p/realsense2_camera/

The latest version of the wrapper should always be able to be built from source code with colcon build if problems with the package version are experienced.

Hello,

One more piece of feedback, it would be nice if in the release notes, the breaking changes would be documented + what action the users should take. As an example, in this PR, the parameter rgb_camera.profile was renamed to rgb_camera.color_profile which breaks the user configuration set for the previous version silently.

I found this one but I don't know what else I'm missing which might cause silent bugs in the future.

Hi @tonynajjar The ROS wrapper release notes are usually meticulous in their detail. Whilst it is possible for omissions to occur on rare occasions, in general their documentation of changes is highly reliable. I appreciate you raising the point.

[tonynajjar]

I agree they are detailed, the PR i mentioned was not ommited, it is in fact mentioned here, my point is not that the Release Notes are lacking, just that it would be helpful to have a Migration Guide i.e. understand which changes in the release notes require a change from the user's configuration. See Nav2's migration guides as an example.

I will pass your feedback about breaking issues to the RealSense ROS development team.
