* include more than 40 pre-configured blocklist sources in a compressed
  json file (/etc/adblock/adblock.sources.gz)
* dynamic SafeSearch support for google, bing, duckduckgo,
  yandex, youtube and pixabay (CNAME (bind) & IP (dnsmaq, unbound))
* DNS backend autodetection
* Download Utility autodetection
* Report Interface autodetection
* Easy cron wrapper to set an adblock related auto-timer for
  automatic blocklist updates
* raw domain/blocklist support (e.g. for dnscrypt support)

* rework online doc
* Complete LuCI rewrite (migrated to client side JS)
