If the installer script linked from [this page]([https://getcomposer.org/doc/faqs/how-to-install-composer-programmatically.md](https://getcomposer.org/doc/faqs/how-to-install-composer-programmatically.md)) is run using PHP 8, it generates the following deprecation notice. ``` Deprecated: Function openssl_free_key() is deprecated since 8.0, as OpenSSLAsymmetricKey objects are freed automatically in Standard input code on line 982 ``` This issue was [fixed in the installer script]([composer/getcomposer.org#159](https://github.com/composer/getcomposer.org/pull/159)), but the documentation was not updated to link to the version of it that includes the fix.
