+
+    The following Bluedroid API have been removed:
+
+    - :component_file:`bt/host/bluedroid/api/include/api/esp_bt_main.h`
+
+        - Remove ``esp_err_t esp_bluedroid_init(void)``
+
+            - Bluedroid stack initialization API has been replaced by ``esp_err_t esp_bluedroid_init_with_cfg(esp_bluedroid_config_t *cfg)``. Macro ``BT_BLUEDROID_INIT_CONFIG_DEFAULT()`` provides the default configuration for the initialization. The original function can be deleted directly.
