Breaking Changes

• bootloader_support: The API bootloader_common_get_partition_description has now been made private, the alternative function esp_ota_get_partition_description should be used. (a2f028a)
• SDMMC/SDSPI: SD cards accept custom frequencies, not only fixed values 20 MHz or 40 MHz. See Storage migration guide for details (7d28aba)
• ESSL: The esp_serial_slave_link is removed from the esp-idf components. Now user should use the component manager to pull it in. See example examples/peripherals/sdio/host/main/idf_component.yml for more details (03d8059)
• Sleep: esp_light_sleep_start now returns two error num when sleep fails: ESP_ERR_SLEEP_REJECT and ESP_ERR_SLEEP_TOO_SHORT_SLEEP_DURATION (f191b2f)
• Storage: All the partition handling APIs and data-type definitions have been moved from the 'spi_flash' to the new component 'esp_partition'. See Storage 5.x migration guide for more details (b14116f)
• esp_chip_info() returns the chip version in the format = 100 * major eFuse version + minor eFuse version. (c546de8)
• Wi-Fi: Modified maximum SoftAP connection number and ESPNOW encrypted connection number. (d89a512)
• Wi-Fi: Changed ESP-NOW receive callback function type (esp_now_recv_cb_t). This change is made to fix potential security issues mentioned in #8574. (8223a59)
• ADC: No longer support ADC2 continuous (DMA) mode on ESP32-S3 and ESP32-C3, search for errata on Espressif website to know more details. Users can force use it by enabling ADC_CONTINUOUS_FORCE_USE_ADC2_ON_C3_S3 (6569be4)

• I2S STD: Enabled left_align in the default slot configuration. For the default and most used case, data_bit_width equals to slot_bit_width, which means left_align does not matter in this case.
  For the case that data_bit_width is shorter than slot_bit_width, enabling left_align is a quite typical usage for almost all the codecs. (190e9e7)
• NimBLE: Updated return type for nimble_port_init / nimble_port_deinit functions. (9916eb6)
• IDF: All dynamic memory allocated by FreeRTOS now defaults to internal memory. To allocate FreeRTOS objects in special memory (e.g., external memory), please use one of the CreateWithCaps() functions in #include "freertos/idf_additions.h. (daf4150)

Known Issues

• In ESP32-H2, the low performance of Thread and BlueTooth are observed on some chips, and the fix is included in a later commit(b0e2f33).
• In ESP32-C6, frequent start-stop wifi will make wifi unable to use.
• In ESP32-C6, there is a small chance of core dump when it acts as SoftAP and transmits packets.
• In ESP32-C6, there is a small chance of core dump when it sends advertisement and scanning.
• In ESP32-C6, DUT might crash or disconnect with AP when light sleep enabled.
• On all chips that support Bluetooth, there is a tiny chance of core dump when the BLE client accidentally disconnected from its server as the server is sending notifications.
