Cookies, bugfixes, and more!

A surprisingly feature-focused patch release with a couple notable bugfixes. This October Isahc opted-in to Hacktoberfest, and we received a couple additions from new contributors. Thanks!

Added

• Add HttpClientBuilder::connection_cache_ttl for configuring how long to keep connections open in the cache. (#93, #237) @gsquire
• Make cookie jar API more useful by adding several new methods, including HttpClient::cookie_jar, Configurable::cookie_jar, CookieJar::get_by_name, Cookie::value, and more! An example of how to use some of these have been added to examples/cookies.rs. (#215, #233) @sagebind
• Add a "Why not use" section to readme. (#234) @sagebind

Fixed

• Fix timeouts and other mid-transfer errors causing unexplained EOFs instead of returning a proper io::Error. (#154, #246) @sagebind
• Fix improper cookie behavior when automatically following redirects, such as not sending any cookies in subsequent requests. (#232, #240) @sagebind

Changed

• Make HttpClient cloneable. This makes it much more convenient to share a client instance between threads or tasks. (#241, #244) @braunse
• Replace middleware API with interceptors API. The middleware-preview crate feature has been removed and the unstable-interceptors feature has been added. The API is still unstable, but addresses a number of problems with the old proposed middleware API. (#42, #206) @sagebind
• Update integration tests to use new testserver (#230) @sagebind

New dialer API with Unix socket support

Init fix and experimental HTTP/3 support

Fixed

• Upgrade curl to 0.4.30 to mitigate potential init-on-non-main-thread with certain TLS engines on certain platforms. (#189) @sagebind

Added

• Allow for experimental HTTP/3 support in libcurl. (This does not enable HTTP/3 support, it just merely allows it if libcurl is compiled with it.) (#185) @sagebind

Fix user agent default headers

Fixed

• Fix built-in user agent overriding client default headers. (#191) @sagebind
• Fix incorrectly named function parameter. (#188) @DBLouis

Changed

• Emit all logs as tracing events, maintaining backward compatability with log records. This has the benefit of optionally providing better diagnostics of HTTP requests when using a tracing subscriber. (#170) @sagebind

Client default headers

Added

• Add the ability to set default outgoing header values to include on all requests when building a custom client. Headers set on a request always take precedence over defaults. (#180, #181, #186) @ansrivas

Dependency Updates

• Update Public Suffix List to c1d5b3c (#184) @sagebind
