Update, February 4, 2016: Microsoft announces that is making available Windows 10 Mobile Insider Preview build 10586.71 to the Slow ring of updates.

While the company hasn’t shared any new details, getting a new build in the Slow ring means that the code is stable enough for daily use, but not yet quite ready for primetime. As such, if you have been skipping previous flights because of bugs and things not working correctly, this might be the one build you may be feel a little more comfortable installing on your phone.
