Thanks for the answers guys.
The github link is especially useful.
Ok, so just to make sure everything is working as intended.
On my BQ Aquaris E4.5 the latest update was performed on 18 June 2017.
Have I missed anything between now and then?
Or even better, where can I consult the latest releases so I don't have to pester you with these questions?
