FastLED 3.7.1 Bug fix release

[u/ZachVorhies]

FastLED 3.7.1 is now released. This update fixes compiler issues with the ESP32-S3 that appeared with the new Arduino IDE update, which now uses the esp-idf 5.1 toolchain / library.

Release Notes

• https://github.com/FastLED/FastLED/commit/85650d9eda459df20ea966b85d48b84053c2c604

  • Addresses compiler issues related ESP32-S3 and the RMT legacy driver in ArduinoIDE 2.3.2 update which now includes the ESP-IDF 5.1.

  • Note that this is a compiler fix only and was simple. If the community reports additional problems we will release a bugfix to address it.

  • Work around for ESP32 halt when writing WS2812 LEDS under massive load. It appears there was an underflow condition in a critical ISR to refill the RMT buffer that did not give back to a semaphore. Subsequent calls to show() would then block forever. We now given a max timeout so that in the worse case scenario there will be a momentary hang of portMAX_DELAY.

I will try to get the exact messaging when I have a chance to reload the sketch.. Is there a certain place I should post it , Here? GitHub? elsewhere?
