jsonrpc

• Set host header to URL hostname instead of resolved IP #578

• Add async support #558
• Update to use latest bitreq v0.3.5.
• This is a semver-breaking release because jsonrpc v0.19.0 was released against bitreq v0.2.0, and bitreq::Error is part of the public API via Error::Bitreq.

• Depend on bitreq 399
• Update MSRV to Rust v1.75.0 #405

• simple_http: throw a specific error when transfer encoding is chunked #114

• params field in Request changed to a generic RawValue instead of an array. #108

• Re-export the minreq crate when the feature is set #102
• Don't treat HTTP errors with no JSON as JSON parsing errors #103

• Add new transport that uses minreq #94
• Bump MSRV to rust 1.48.0 #91

• simple_http: fix "re-open socket on write failure" behavior #84 #86
• simple_http: add "host" header (required by HTTP 1.1) #85
• simple_http: add ability to replace URL/path; minor ergonomic improvements #89

This release significantly improves our simple_http client, though at the apparent cost of a performance regression when making repeated RPC calls to a local bitcoind. We are unsure what to make of this, since our code now uses fewer sockets, less memory and does less redundant processing.

The highlights are:

• Support JSON replies that span multiple lines #70
• Add feature-gated support for using a SOCKS proxy #70
• Fix resource exhaustive bug on MacOS by reusing sockets #72 #76

As well as improvements to our code quality and test infrastructure.

This release increases the MSRV to 1.41.1, bringing with it a bunch of new language features.

Some highlights:

• The MSRV bump #58
• Add IPv6 support #63
• Remove serder_derive dependency #61

Features

• A new set of transports were added for JSONRPC over raw TCP sockets (one using SocketAddr, and one UNIX-only using Unix Domain Sockets)

Bug fixes

• The Content-Type HTTP header is now correctly set to application/json
• The Connection: Close HTTP header is now sent for requests

• Remove http and hyper dependencies
• Implement our own simple HTTP transport for Bitcoin Core
• But allow use of generic transports

• Clean up the API
• [Set the content-type header to json]((https://github.com/apoelstra/rust-jsonrpc/pull/21)
• Allow no result field in responses
• Add batch request support
