Documentation for IDF v5.3.2 is available at https://docs.espressif.com/projects/esp-idf/en/v5.3.2/

ESP-IDF v5.3.2 is a bugfix update for ESP-IDF v5.3.

Obtaining v5.3.2

For full installation instructions, see the ESP-IDF Programming Guide.

The source files attached to this release will not work due to our use of git submodules. Use one of the following methods instead:

Using git

To get this release, use the following commands:

git clone -b v5.3.2 --recursive https://github.com/espressif/esp-idf.git esp-idf-v5.3.2
cd esp-idf-v5.3.2/

This is the recommended way of obtaining v5.3.2 of ESP-IDF.

Download an archive with submodules included

Attached to this release is an esp-idf-v5.3.2.zip archive. It includes .git directory and all the submodules, so can be used out of the box. This archive is provided for users who have connectivity issues preventing them from cloning from GitHub.

Major changes

This is the list of changes since release v5.3.1:

Thread: Supported Thread Radio Encapsulation Link (TREL) feature (47dc6f3)

Breaking Changes

MbedTLS option MBEDTLS_ECP_FIXED_POINT_OPTIM is disabled by default to save on significant (~27KB) flash footprint. This allows easier migration from IDF 4.x to 5.x release. If the performance is desired and ECC accelerator is not available then the config can be turned on.
MbedTLS Support for SHA3 operations is now configurable and disabled by default to save flash size. The config MBEDTLS_SHA3_C can be enabled if an application needs to perform SHA3 operations.

Known Issues

For ESP32-P4 chips, when ESP_SLEEP_KEEP_DCDC_ALWAYS_ON is not enabled (enabled by default), accessing external storage (Flash/ PSRAM) after waking up from light sleep may get incorrect data.

Known issues are planned to be fixed before the next v5.3 release.
