+  - "Support for Ansible 2.9 and ansible-base 2.10 is deprecated, and will be removed in the next major release (community.network 4.0.0) this spring.
+     While most content will probably still work with ansible-base 2.10, we will remove symbolic links for modules and action plugins, which will make
+     it impossible to use them with Ansible 2.9 anymore. Please use community.network 3.x.y with Ansible 2.9 and ansible-base 2.10, as these releases
+     will continue to support Ansible 2.9 and ansible-base 2.10 even after they are End of Life
