..note:: Please note that http parser functionality which was previously part of ``nghttp`` component is now part of :component:`http_parser <http_parser>` component.
These components can be installed using ``idf.py add-dependency`` command.
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 <https://semver.org/>`_ 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 </api-reference/network/esp_netif>` component instead; you can follow the `Migration guide to ESP-NETIF<tcpip-adapter>`
..note:: OpenSSL-API component is no longer supported. It is not available in the IDF Component Registry, either. Please use :doc:`ESP-TLS </api-reference/protocols/esp_tls>` or :component:`mbedtls` API directly.
