Features

Added support for the new DSA bridge syntax to the OpenWrt backend
Added support for Wireguard and Wireguard/VXLAN
Added support for Wireguard interfaces in OpenWrt backend
Added support for VXLAN interfaces in OpenWrt backend
Added auth_nocache proprety to the OpenVpn backend
Added support for OpenVPN tls-auth option, the OpenVPN backend will
automatically create a file for the key present in "tls_auth"
field and update the value of the "tls-auth" parameter
Added proto to remote setting of the OpenVpn backend
Added support for IEEE 802.11w configurations to the OpenWrt
backend
Added support for Wifi6 / IEEE 802.11ax to the OpenWrt backend
Added support for basic IEEE 802.11r options to the OpenWrt
backend
Added support for WPA3 to the OpenWrt backend
Added support for EAP-PEAP as auth method in WPA2 enterprise wifi
client configuration of OpenWrt backend
Removed option of 2.4GHz radio for 802.11ac from the OpenWrt
backend

Changes

By default, the OpenWrt backend now generates bridge syntax in the
new DSA compatible format, to override this, dsa=False must be
passed during the initialization of the backend

Dropped support for Python 3.6
Added support for Python 3.8 and 3.9
Upgraded Jinja to 3.0
Upgraded jsonschema to 3.2.x
Upgraded to openwisp-utils 1.0.x and reformatted code with latest
version of the black formatter

Simplified bridging of wifi interfaces in the OpenWrt backend: users
can now simply add a wifi interface to a bridge and forget about
having to update also the attached networks of the OpenWrt
configuration

Ensured values are always deep copied when using merge_config,
without this change the different schemas remain interwined and a
dynamic change to one part which is reused by other schemas will
affect different backends inadvertently
The file path is not allowed to be an empty string anymore
Ignored duplicate list elements when merging templates: detect
identical elements present in both lists to avoid adding the
duplicate to the result; this is needed because some templates may
share one or multiple common files and these do not not have to be
duplicated
Fixed typo in EAP TTLS protocol enum_title of OpenWrt backend:
it was showing EAP-PEAP even though TTLS was set
Fixed madwifi driver for legacy systems
Fixed comp-lzo option for legacy OpenVPN in OpenWisp1 backend
Fixed UCI format backward compatibility with OpenWISP 1 This fix is
needed to allow workarounds in the code of OpenWISP-Firmware to keep
working also with OpenWISP 2
