ureq 3.x release candidate 1

ureq is a lightweight, sync, HTTP/1.1 library. 3.x is rewritten from the ground up in a Sans-IO pattern with heavy use of type state variables. The library is now split in a protocol crate (hoot) and the client (ureq). I have just pushed the 3.x release candidate 1 to crates.io.

Some highlights:

• API based on the HTTP crate
• Bring your own transport (and bespoke resolvers).
• ![forbid(unsafe\_code)]
• Less allocations

Happy to answer any questions.
