ESPHome 2026.6.4 released on 01-07-2026
ESPHome 2026.6.4 is out now. It brings targeted reliability fixes for RP2040 ADC VSYS handling, a restore of correct ES8388 DAC mute/unmute behaviour, and a number of stability improvements for MIPI‑SPI displays and wireless subsystems.
See the ESPHome GitHub release notes for full details and links to the individual fixes.
What’s in this release
- RP2040 ADC: ADC code only calls cyw43_thread_enter/exit for VSYS when Wi‑Fi is active, avoiding unnecessary thread/VSYS interactions when Wi‑Fi is off.
- ES8388 DAC: Fixed an issue where the ES8388 DAC could not be unmuted once muted, restoring reliable mute/unmute behaviour.
- MIPI‑SPI and wireless fixes: several mipi_spi transfer/timing fixes for improved panel reliability; espnow drops oversized received frames to prevent buffer overflows; bluetooth_proxy no longer triggers a -Wtype-limits warning with active: false; plus a multicast typo fix in config validation.
