I'm a bit late with this, as the latest data (up to September 30th) was released last week. To make up, here's Andy Lee Robinson's latest video showing the PIOMAS sea ice volume minimum long-term trend:
Sea ice volume stays relatively stable during September, with some years going up a bit, others still going down a bit. 2015 had a very small uptick of just 57 km3, similar to 2012's increase of 35 km3, so no changes there, this year still has 2000 km3 more ice than the 2012 record smasher. But with 2013 going up by 169 km3, the gap has become so small (289 km3) that this year is almost on a par with the first rebound year. And it's still 1087 km3 below last year's further rebound.
These differences are more visible on Wipneus' PIOMAS volume graph:
With 2015 ending as 5th on record, the trend hasn't gone back to the drastic decline of the 2007-2012 period, but neither has it confirmed any suspicions of recovery. It is simply continuing the downward linear trend, as can be seen on the PIOMAS sea ice volume anomaly graph:
