Yes, there's now been published a single poll which has him outside the MoE of zero. (Not outside the MoE of his polling average for any month since October, though, and statistically you'd expect with the number of polls at least one with him at 8% if he was just hovering at 3.5% for this long.)
While that's a landmark, I guess, it's a thin reed to ground a conclusion of any, much less rapid or exponential, progress.
