Two breaking changes banked for ESPHome 2026.10.0
External components touching remote_base, select options or light effects will need edits when the stable drops — it's not out yet, beta 4 is the newest tag.
Also today: Supervisor 2026.10.2 shipped yesterday but stable.json still pins 2026.09.3 — and Hue lamp firmware 1.164.2 lets mains-powered bulbs run Zigbee and Matter at once, bridgeless.
Production ESPHome devices stay on 2026.9.0 until the .0 drops — and four betas in seven days says that's close.
