 In comparison to the original [esp32-arduino-lib-builder](https://github.com/espressif/esp32-arduino-lib-builder), this repository is used for recompiling specific versions of the SDK in `arduino-esp32` and has the following branches:
 
 * `release/*` is used to recompile the original SDK for a specified version.
-* `debug/*` is used to recompile debug versions based on a specified SDK version.
 * `high_perf/*` is used to recompile high performance versions based on a specified SDK version. It changes some configurations (as below) and can achieve higher performance in some cases, especially for avoiding [screen drifting](https://docs.espressif.com/projects/esp-faq/en/latest/software-framework/peripherals/lcd.html#why-do-i-get-drift-overall-drift-of-the-display-when-esp32-s3-is-driving-an-rgb-lcd-screen) when using RGB LCDs.

-### Debug Versions
-
-Due to the support of specifying the LOG level when compiling v3.x and above versions in esp32-arduino-lib-builder, the branches here are only used to compile debug versions of v2.x.

-* [debug/v2.0.13](https://github.com/esp-arduino-libs/esp32-arduino-lib-builder/tree/debug/v2.0.13)
-* [debug/v3.0.0](https://github.com/esp-arduino-libs/esp32-arduino-lib-builder/tree/debug/v3.0.0)

 ### High Performance Versions
 
 As only v3.x and above versions support the required high-performance configurations, the branches here are only used for compiling the high_perf version of v3.x.
