+# Release Notes
+
+## Zenoh in gz-transport
+
+Gazebo now supports Zenoh as an alternative transport implementation, offering
+improved discovery, interoperability, and performance. To enable Zenoh, set the
+environment variable `export GZ_TRANSPORT_IMPLEMENTATION=zenoh`. This allows
+Gazebo to leverage Zenoh's features and potentially integrate more seamlessly
+with ROS 2 and other systems utilizing Zenoh.
+
+See the [tracking issue](https://github.com/gazebosim/gz-transport/issues/559)
+and the implementation pull request
+<https://github.com/gazebosim/gz-transport/pull/665> for more details.
+
+## Remove major version from package names
+
+We have refactored package naming to remove major version numbers, simplifying
+dependency management and reducing maintenance overhead. This change impacts how
+Gazebo packages are identified in CMake builds, package installations, and
+import statements.
+
+See the
+[tracking issue](https://github.com/gazebo-tooling/release-tools/issues/1244)
+for more details.
+
+## Migrate from Qt5 to Qt6
+
+With Qt5 reaching
+[end of life](https://www.qt.io/blog/extended-security-maintenance-for-qt-5.15-begins-may-2025),
+Gazebo has been migrated to Qt6. While there are no major changes to end-users
+of the Gazebo GUI, `gz-gui` plugin authors will need to make changes to ensure
+compatibility with Qt6. Make sure to check out the
+[migration guide](https://gazebosim.org/api/gui/10/migration_qt6.html).
+
+See the [tracking issue](https://github.com/gazebosim/gz-gui/issues/586) and the
+implementation pull requests <https://github.com/gazebosim/gz-gui/pull/666> and
+<https://github.com/gazebosim/gz-sim/pull/2832> for more details
+
+## Implement ROS standard simulation interfaces
+
+Gazebo now supports the standard ROS 2
+[simulation interfaces](https://github.com/ros-simulation/simulation_interfaces),
+enabling seamless integration with ROS 2 ecosystems and providing access to
+features for controlling and querying the simulation state. Documentation has
+also been added to guide users on utilizing these new interfaces.
+
+See the [tracking issue](https://github.com/gazebosim/ros_gz/issues/732) and the
+implementation pull requests <https://github.com/gazebosim/ros_gz/pull/790> and
+<https://github.com/gazebosim/docs/pull/601> for more details
+
+## Resolve auto inertia based on input mass
+
+Automatically computed inertial can now use the `mass` specified in the SDF file
+and no longer requires setting the density of collision objects. When both mass
+and density are set, Gazebo now correctly scales the auto-computed inertia based
+on the specified mass, respecting the density ratios between collisions.
+
+See the [tracking issue](https://github.com/gazebosim/sdformat/issues/1482) and
+the implementation pull request
+<https://github.com/gazebosim/sdformat/pull/1513> for more details
+
+## Improve Gazebo APIs for Reinforcement Learning
+
+Several APIs have been improved to streamline reinforcement learning pipelines.
+We have also added an [example integration with StableBaselines3](https://github.com/gazebosim/gz-sim/tree/gz-sim10/examples/scripts/reinforcement_learning/simple_cart_pole)
+for reinforcement learning, enabling users to experiment with RL algorithms within
+Gazebo. The example provides a starting point for developing and testing robotic
+control policies.

+and <https://github.com/gazebosim/gz-sim/pull/2647> for more details
+
+## Standalone executables for the `gz` tool
+
+Previously, the `gz` tool, a Ruby-based CLI interface, offered subcommands by
+loading shared libraries provided by each of the Gazebo libraries. This approach
+had several downsides including difficulty with debugging with `gdb`,
+portability issues when running on Windows or macOS. With the new approach each
+of the libraries provide standalone executables that are spawn by the `gz` tool.
+The standalone executables can be executed directly if desired, making it
+significantly easier to run under `gdb`. Unlike loading shared libraries,
+running executables is much more straightforward and does not have any of the
+portability issues of the previous approach.
+
+See the [tracking issue](https://github.com/gazebosim/gz-tools/issues/7) and one
+of the implementation pull requests
+<https://github.com/gazebosim/gz-sim/pull/2849> for more details
+
+## Parallel asset download
+
+This enhancement significantly improves Gazebo's startup time and responsiveness
+when loading worlds with many assets. Assets are now downloaded in parallel,
+allowing the GUI to remain interactive during the loading process and enabling
+users to close the window if needed.
+
+See the [tracking issue](https://github.com/gazebosim/gz-sim/issues/1260) and
+one of the implementation pull requests
+<https://github.com/gazebosim/gz-sim/pull/2992> for more details
+
+## Occupancy Grid Export
+
+This enhancement adds a plugin that enables end users to directly export occupancy
+grids for use with Nav2 or other mobile robotics software. 
+
+See the pull request <https://github.com/gazebosim/gz-sim/pull/2958> for more details.
