New chip in latest Neopixel strips?
We've bought a few meters of Neopixel strips this week and FastLED isn't behaving with them as it did before. Has the controller changed? Neopixel strandtest works fine.

There is a "B" version of the WS2812. We have been getting the B version for a while now and all the new strips are shipping with that. The WS2812A is a 6-pin chip and the WS2812B has 4 pins.

Thanks Bill,
One of the other Resistors used a Saelae analyzer to find out we needed to slow the timings in the WS2811_800Khz class when using the Flora with it by ~83%
Here's a quick diff since I'm about out of energy for today:
root@blackbook:~/sketchbook/libraries/FastLED# diff chipsets.h chipsets.h.bak
279c279
< class WS2811Controller800Khz : public ClocklessController<DATA_PIN, NS(333), NS(333), NS(375), RGB_ORDER> {};
---
> class WS2811Controller800Khz : public ClocklessController<DATA_PIN, NS(400), NS(400), NS(450), RGB_ORDER> {};
