ESPHome 2026.6.3 released on 29-06-2026

ESPHome 2026.6.3 is out now. It bumps several dependencies (including zeroconf and the bundled esphome-device-builder), fixes ESP32 toolchain and secure-boot handling, and brings a raft of networking, Wi‑Fi/ESP‑NOW and display-driver stability improvements.
See the project’s GitHub release page for the full changelog and upgrade instructions.
What’s in this release
- Dependency bumps and multiple esphome-device-builder patch updates (zeroconf to 0.150.0; esphome-device-builder up to 1.0.21) for incremental fixes and packaging improvements.
- ESP32 tooling and secure-boot fixes: framework checks ignore unrelated broken PATH tools, ESP-IDF refs accept ‘#’ separators, and secure-boot keys now use POSIX paths.
- Networking and stability fixes: IPv4 type tags applied across lwIP platforms, ESP8266 reports STA IP correctly, ESP-NOW RX no longer throttled with deep_sleep, and espnow.send() no longer crashes without a callback.
Upgrade notes
- Secure-boot signing/verification keys now use POSIX paths—if you manage secure-boot keys on non-POSIX hosts, adjust or test your key paths and signing/verification steps before upgrading.
- No breaking deprecations are listed in the release notes; if you need to revert, obtain the prior release from the project’s GitHub.
