For example, to install libsodium component with exact version X.Y, run: ``idf.py add-dependency libsodium==X.Y``. To install libsodium component with the latest version compatible to X.Y according to `semver `_ rules, run: ``idf.py add-dependency libsodium~X.Y``. To find out which versions of each component are available, open https://components.espressif.com, search for the component by its name and check the versions listed on the component page. Following components are removed since they were deprecated in IDF v4.x * ``tcpip_adapter`` Please use the :doc:`ESP-NETIF ` component instead; you can follow the `Migration guide to ESP-NETIF` .. note:: OpenSSL-API component is no longer supported. It is not available in the IDF Component Registry, either. Please use :doc:`ESP-TLS ` or :component:`mbedtls` API directly.
