OpenSSL 1.0.2 (LTS) has been end-of-life since 31 Dec 2019, and OpenSSL 1.1.0 since 11 Sep 2019, and now OpenSSL 1.1.1 (LTS) has also reached end-of-life (OpenSSL 1.1.1 End of Life - OpenSSL Blog).
Erlang OTP 24.3 (Erlang OTP 24.3 is released - Erlang/OTP) was released 10 Mar 2023 with the crypto app updated to allow being “compiled, linked, and used with OpenSSL 3.0 cryptlib”.
When might confd-8.0.x get updated to use the updated Erlang OTP to continue to support OpenSSL usage with the OpenSSL 3.x now being the only active codebase, before it gets to the EOM milestone. The 8.0.4 was packaged with Erlang/OTP version: 22.3.4.17.
