+<!-- TODO(rsanchez15): Remove this before releasing v3.0.0 -->
+> [!WARNING]
+> **In preparation for Fast DDS v3.0.0, eProsima/dev-utils' master branch is undergoing major changes entailing API breaks.**
+> **Until Fast DDS v3.0.0 is released, it is strongly advisable to use the latest stable branch, [0.x](https://github.com/eProsima/dev-utils/tree/0.x), which uses Fast DDS 2.14.x**.

 The packages that conform this repository are:
 
 * **CMake utils**: `cmake_utils` CMake utilities to build packages.
