Back in December was word that cURL would be dropping its "Hyper" Rust HTTP back-end due to little demand and lack of developer interest for that experimental code. The cURL 8.12 release is out today with Hyper stripped out.

Hyper had been a Rust-based HTTP back-end for cURL to provide memory safety guarantees while the rest of cURL remains in C code. While Hyper was initially written as sponsored work, there was little end-user and developer interest over the years for this experimental back-end. As such cURL lead developer Daniel Stenberg decided it best to just drop this back-end.

With today's cURL 8.12 release that Hyper code is stripped away. Plus cURL 8.12 has other improvements like OpenSSL support to use keys and certificates from PKCS#11 provider, ssls-export for SSL session import/export, build system updates, and many bug fixes.
