Almost ready! Latest Controller, Notifications, Firmware Upgrader

[Federico Capoano]

On the master branch of ansible-openwisp2, several improvements are now available:

- latest version of openwisp-controller (0.8.x, see change log to know what changed)

- a new module installed by default: openwisp-notifications

- latest version of openwisp-network-topology (0.8.x, see change log to know what changed)

- latest version of openwisp-users (0.5.x, see change log from 0.4.x to 0.5.x to know what changed)

- a new optional module openwisp-firmware-upgrader

I encourage anyone who has time or needs these modules to help us test these changes, the goal is to release all the work we've been doing in the last months so that the whole community can benefit from it.

After this work is completed, we'll focus our next iterations on releasing and packaging openwisp-monitoring, openwisp-radius and openwisp-wifi-login-pages.

Best regards
