 ### Builds after release 0.12.0
 
+#### Build 2202210
+
+-   Fixed HTTP API commands not applying to all selected segments if called from JSON
+-   Improved Stream effects, no longer rely on LED state and won't fade out at low brightness
+
 #### Build 2202200
 
 -   Added `info.leds.seglc` per-segment light capability info (PR #2552)

-PCCOOLER | Moonlight 5-pack Fans | Uses WS2812B, includes Data-out connector to keep each fan uniquely addressable if wired in series like traditional LED strips
-Any | 5v 3-pin ARGB for PC | Any PC RGB device that supports the 5v 3-pin ARGB motherboard header should work fine with WLED. All the major motherboard vendors support the Corsair HD120 and PCCOOLER fans listed, so we can safely assume any device that supports motherboard ARGB 5V 3-Pin standard will work with WLED.
