IDF Monitor follows the custom console baud-rate (:ref:`CONFIG_ESP_CONSOLE_UART_BAUDRATE`) by default instead of 115200. Setting a custom baud rate is not supported from menuconfig anymore. A custom baud-rate can be specified from command line with the ``idf.py monitor -b <baud>`` command or through setting environment variables. Please note that the baud-rate argument has been renamed from ``-B`` to ``-b`` in order to be consistent with the global baud-rate ``idf.py -b <baud>``. Run ``idf.py monitor --help`` for more information.
``idf.py`` sub-commands and ``cmake`` targets are unified to contain ``-`` instead of ``_``. The following changes have been made. Deprecated sub-commands and targets produce a warning. It is advised to migrate to the new ones.
