ESPHome

I installed the ESPHome 2023.6 update this morning. During update of the ESP devices, a warning appeared for three of four devices during code compile. This is the first time a warning occurred when updating the devices. The warning is shown below.

The three problematic devices are used for door open/closed detection, water level and salt level warnings. This warning noted above never occurred during past updates. Why now?
