Curl is removing support for the RTMP protocol suite after nearly 16 years, citing minimal user adoption (2.2% in a 2025 survey), no upstream testing in the librtmp library, and lack of developer maintenance. The curl project announced the removal six months prior and will ship the first RTMP-free version, 8.20.0, on April 29, 2026, while reducing supported URL schemes from 33 to 27.
