rtmp: drop support 
- librtmp has no test cases, makes no proper releases and has not had a
  single commit within the last year

- librtmp parses the URL itself and requires non-compliant URLs for this

- we have no RTMP tests

- RTMP was used by 2.2% of curl users (self-identified in the 2025
  survey)

Closes #20673

Raw Blame History

Items to be removed from future curl releases

If any of these deprecated features is a cause for concern for you, please email the curl-library mailing list as soon as possible and explain to us why this is a problem for you and how your use case cannot be satisfied properly using a workaround.

c-ares 1.16.0

In March 2026, we drop support for all c-ares versions before 1.16.0.

TLS-SRP Authentication

Transport Layer Security Secure Remote Password is a TLS feature that does not work with TLS 1.3 or QUIC and is virtually unused by curl users and in general.

TLS-SRP support gets removed in August 2026.

SMB goes opt-in

The SMB protocol has weak security and is rarely used these days. After curl 8.19.0 SMB support becomes opt-in.

NTLM goes opt-in

The NTLM authentication method has weak security and is rarely used these days. It has been deprecated by Microsoft and does not work over HTTP/2 or HTTP/3.

After curl 8.19.0 NTLM support becomes opt-in.
