Removed or Deprecated Components
Components Moved to ESP-IDF Component Registry
Following components are removed from ESP-IDF and moved to ESP-IDF Component Registry:
Note
Please note that http parser functionality which was previously part of nghttp component is now part of http_parser component.
These components can be installed using idf.py add-dependency command.
For example, to install libsodium component with the 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.
Deprecated Components
The following components are removed since they were deprecated in ESP-IDF v4.x:
tcpip_adapter. Please use the ESP-NETIF component instead; you can follow the TCP/IP Adapter.
Note
OpenSSL-API component is no longer supported. It is not available in the IDF Component Registry, either. Please use ESP-TLS or mbedtls API directly.
Note
esp_adc_cal component is no longer supported. New adc calibration driver is in esp_adc component. Legacy adc calibration driver has been moved into esp_adc component. To use legacy esp_adc_cal driver APIs, you should add esp_adc component to the list of component requirements in CMakeLists.txt. Also check Peripherals Migration Guide for more details.
