Congrats to the Open Robotics team and everyone who contributed to this release!
Calling out a couple changes I'm excited about that we (Foxglove) helped contribute to:
- MCAP is now the default logging format in Rosbag2[0]. This is a much more performant and configurable format than the previous default (SQLite-based). SQLite is still a fully supported alternative.
- Message type definitions (schemas) can now be exchanged at runtime[1]. This means that tools such as rosbag2, or visualization tools such as Foxglove Studio[2] can now communicate with a ROS system over the network without needing a copy of the source code or complete ROS workspace.
