The main 'Threshold' branch of Windows 10 just got itself a big 'Patch Tuesday' update, for desktop/laptop/hybrid/phones, with the changelog quoted below. There's definitely some stuff below that's mobile-relevant. Build 10586.218 is now available as an update to all phones upgraded to Windows 10 Mobile, even if they're not officially approved, i.e. this is for both production W10 phones and all Insider-registered devices. Happy downloading!

You've got to love the huge number of apps and featured mentioned under 'Fixed additional issues with'... Build 10586.218 does seem like a significant update under the hood - and it also marks the point in time where we can expect 'Patch Tuesday' updates to our smartphones in the same way that we've become used to with our laptops etc.
