**micro-ROS Humble release!**  
Congratulations for the release of ROS 2 Humble Hawksbill from micro-ROS!

We worked as fast as possible to get the small turtle ready, and are proud to announce the corresponding [micro-ROS Humble release](https://github.com/micro-ROS/micro_ros_setup/discussions/509). Careful, it just hatched.

Since last year a lot has happened in ROS 2 but not less in micro-ROS!  
First and foremost, [micro-ROS](https://micro.ros.org/) was able to drastically improve its overall performance, making the framework less memory-hungry, more reliable, more multi-thread capable and real-time ready.

Further important features included until this Humble release are:

- [new RCLC characteristics](http://discourse.ros.org/t/ros-2-humble-hawksbill-released/25729/14?u=katrin_kellner)
- new support for various boards: RENESAS RA Family, TI Tiva™ C Series,
- new support for numerous platforms: Platforms IO, St STMCube, Microsoft Azure RTOS, Espressif ESP-IDF
- new [embeddedRTPS experimental RMW](http://discourse.ros.org/t/embeddedrtps-the-new-experimental-middleware-for-micro-ros/22741)
- [Micro XRCE-DDS v2.1.1](https://github.com/eProsima/Micro-XRCE-DDS/releases/tag/v2.1.1)

All the details can be found in the [micro-ROS Humble release notes](https://github.com/micro-ROS/micro_ros_setup/releases/tag/3.0.0).  
Get creative!
