SPI Flash: Now HPM-DC (Quad Flash > 80MHz on some flash models) is no longer enabled by default because it needs bootloader support. Without this support, some flash chips are not able to run > 80 MHz.

WIFI_REASON_NO_AP_FOUND_IN_RSSI_THRESHOLD (2fa1e2b)

Known Issues

No Docker images have been published for v5.2-beta1 release on Docker Hub.
The ESP32-C3 and ESP32-S3 may experience a system crash with a low probability during the BLE connection update or channel map update procedure.
There is a possibility of unintended memory writes due to an issue in the NimBLE host when handling bonded peers.
Chips fail to connect to AP with WEP encryption.This has been fixed in 83d9e817

Known issues are planned to be fixed before the final v5.2 release.
