ESPHome 2026.4.0 is out — ESP32 runs 34% faster! 🚀
Heads up if you're running ESP32 with ESPHome — the new 2026.4.0 release brings serious performance improvements:
🔹 Default CPU frequency bumped to 240MHz (up from 160MHz)
🔹 API encryption handshake 29% faster (90ms → 64ms)
🔹 Protobuf encoding 34% faster
🔹 BLE ad encoding 20-33% faster
🔹 +40KB extra IRAM for smoother Wi-Fi, BLE & API ops
Basically your existing ESP32 hardware just got ~34% faster for free. No new board needed.
⚠️ Heads up:
- LVGL users: rotation settings must move into the lvgl: block
- Don't enable the 40KB IRAM option if you're on a bootloader older than v5.1 — it'll brick your device
💡 Smart home folks running ESP32 + Home Assistant — update now, you'll feel the difference.
