The dual-signal WS2812B. Each LED takes data from both its predecessor and the one before that, so one dead LED does not blank everything downstream - which is why it is the sensible choice for anything installed behind a wall.
The pinout here is the 6-pin arrangement; the exact pin numbering has not been verified against a WorldSemi datasheet. See DATA-QUALITY.md.
Variants

Protocol — WS2813
Timings shown from datasheet. Other sources disagree; see the protocol page.
Compatibility
-
near clone
WS2812B
Close enough that libraries drive it with WS2812 timings, but it needs a longer reset (300 us) and has a second data input, so it is a 5-pin part on strip. Not pin-compatible.
-
protocol compatible of this
WS2814
Same timing family and backup line, but four channels rather than three.
-
near clone of this
WS2815
Same backup-data-line concept, but 12 V and a different bit period. Do not assume WS2813 timings will drive it.
Dating evidence
Nobody announces these parts, so this records what we can actually cite rather than a release date. Library support proves only that the part existed by that date.
