Walkthrough

The ESP32 IDF V5 environment now uses a newer Tasmota platform with Arduino Core 3.3.8 and IDF 5.5.4. Compatibility guards were updated for __unreachable, mbedTLS SHA1 support, and time_t declarations.

Changes

ESP32 IDF V5 compatibility

Layer / File(s)	Summary
ESP32 IDF V5 platform update platformio.ini	The ESP32 IDF V5 platform changed to Tasmota 2026.05.50. The environment now defines __unreachable as __builtin_unreachable.
Library compatibility guards wled00/mbedtls_sha1_shim.cpp, wled00/src/dependencies/time/TimeLib.h	The SHA1 shim uses MBEDTLS_SHA1_C. The fallback time_t definition also checks _TIME_T_DECLARED.

Estimated code review effort: 2 (Simple) | ~10 minutes
