IDF Monitor
IDF Monitor makes the following changes regarding baud-rate:
- IDF monitor now uses the custom console baud-rate (CONFIG_ESP_CONSOLE_UART_BAUDRATE) by default instead of 115200. 
- Setting a custom baud from menuconfig is no longer supported. 
- 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 - -Bto- -bin order to be consistent with the global baud-rate- idf.py -b <baud>. Run- idf.py monitor --helpfor more information.
Deprecated Commands
idf.py sub-commands and cmake target names have been unified to use hyphens (-) instead of underscores (_). Using a deprecated sub-command or target name will produce a warning. Users are advised to migrate to using the new sub-commands and target names. The following changes have been made:
| Old Name | New Name | 
|---|---|
| efuse_common_table | efuse-common-table | 
| efuse_custom_table | efuse-custom-table | 
| erase_flash | erase-flash | 
| partition_table | partition-table | 
| partition_table-flash | partition-table-flash | 
| post_debug | post-debug | 
| show_efuse_table | show-efuse-table | 
| erase_otadata | erase-otadata | 
| read_otadata | read-otadata | 
Esptool
The CONFIG_ESPTOOLPY_FLASHSIZE_DETECT option has been renamed to CONFIG_ESPTOOLPY_HEADER_FLASHSIZE_UPDATE and has been disabled by default. New and existing projects migrated to ESP-IDF v5.0 will have to set CONFIG_ESPTOOLPY_FLASHSIZE. If this is not possible due to an unknown flash size at build time, then CONFIG_ESPTOOLPY_HEADER_FLASHSIZE_UPDATE can be enabled. However, once enabled, to keep the digest valid, a SHA256 digest will no longer be appended to the image when updating the binary header with the flash size during flashing.
Windows Environment
The Msys/Mingw-based Windows environment support got deprecated in ESP-IDF v4.0 and was entirely removed in v5.0. Please use ESP-IDF Tools Installer to set up a compatible environment. The options include Windows Command Line, Power Shell and the graphical user interface based on Eclipse IDE. In addition, a VS Code-based environment can be set up with the supported plugin: https://github.com/espressif/vscode-esp-idf-extension.
