v0.15.0

[v0.15.0] - 2022-07-20

v0.15.0 is a breaking release. The main changes are:

• It's now possible to apply resource limits to subscriptions as well as regular calls.
• We now allow trait bounds to be overridden in the proc macros. See examples/examples/proc_macro_bounds.rs for examples.
• We've tidied up the subscription API, removing the PendingSink concept (you can still manually accept or reject a sink, but otherwise it'll be accepted automatically if you send a message down it) (#799).
• Our logging Middleware trait has been split into HttpMiddleware and WsMiddleware to better capture the differences between the two. if you use custom middleware, you'll need to implement one or the other trait on it depending on your used transport method (#793). We also provide params and the method type to middleware calls now, too (#820).
• We've consistified the API for setting headers across HTTP and WS clients (#799).
