+Tested with the Ansible 2.11, 2.12, and 2.13 releases, and the current development version of Ansible. Ansible-core versions before 2.11.0 are not supported. In particular, ansible-base 2.10 and Ansible 2.9 are not supported. Use community.network 3.x.y if you are using Ansible 2.9 or ansible-base 2.10.
 
 ### Supported connections
 The community network collection supports `network_cli`  and `httpapi` connections.

+  - The community.network collection no longer supports Ansible 2.9 and ansible-base 2.10. While we take no active measures to prevent usage, we will remove compatibility code and other compatility measures that will effectively prevent using most content from this collection with Ansible 2.9, and some content of this collection with ansible-base 2.10. Both Ansible 2.9 and ansible-base 2.10 will very soon be End of Life and if you are still using them, you should consider upgrading to ansible-core 2.11 or later as soon as possible (https://github.com/ansible-collections/community.network/pull/426).
