# 2.0.0

 * Remove the "synthetic error" concept. Methods that formerly returned
   Response now return Result<Response, Error>.
 * Rewrite Error type. Instead of an enum, it's now a struct with an
   ErrorKind. This allows us to store the source error when appropriate,
   as well as the URL that caused an error.
 * Move more configuration to Agent. Timeouts, TLS config, and proxy config
   now require building an Agent.
 * Create AgentBuilder to separate the process of building an agent from using
   the resulting agent.
 * Rewrite README and top-level documentation.
 * Add ureq::request_url and Agent::request_url, to send requests with
   already-parsed URLs.
 * Remove native_tls support.
 * Remove convenience methods `options(url)`, `trace(url)`, and `patch(url)`.
   To send requests with those verbs use `request(method, url)`.
 * Remove Agent::set_cookie.
 * Remove Header from the public API. The type wasn't used by any public
   methods.
 * Remove into_json_deserialize. Now into_json handles both serde_json::Value
   and other types that implement serde::Deserialize. If you were using
   serde_json before, you will probably have to explicitly annotate a type,
   like: `let v: serde_json::Value = response.into_json();`.

# 1.5.2

 * Remove 'static constraint on Request.send(), allowing a wider variety of
   types to be passed. Also eliminate some copying. (#205).
 * Allow turning a Response into an Error (#214).
 * Update env_logger to 0.8.1 (#195).
 * Remove convenience method for CONNECT verb (#177).
 * Fix bugs in handling of timeout_read (#197 and #198).

# 1.5.1

 * Use cookie_store crate for correct cookie handling (#169).
 * Fix bug in picking wrong host for redirects introduced in 1.5.0 (#180).
 * Allow proxy settings on Agent (#178).

# 1.5.0

 * Add pluggable name resolution. Users can now override the IP addresses for
   hostnames of their choice (#148).
 * bugfix: Don't re-pool streams on drop. This would occur if the user called
   `response.into_reader()` and dropped the resulting `Read` before reading all
   the way to EOF. The result would be a BadStatus error on the next request to
   the same hostname. This only affected users using an explicit Agent (#160).
 * Automatically set Transfer-Encoding: chunked when using `send` (#86).
 * `into_reader()` now returns `impl Read + Send` instead of `impl Read` (#156).
 * Add support for log crate (#170).
 * Retry broken connections in more cases (should reduce BadStatus errors; #168).

# 1.4.1

 * Use buffer to avoid byte-by-byte parsing result in multiple syscalls.
 * Allow pooling multiple connections per host.
 * Put version in user agent "ureq/1.4.1".

# 1.4.0

  * Propagate WouldBlock in io:Error for Response::to_json.
  * Merge multiple cookies into one header to be spec compliant.
  * Allow setting TLSConnector for native-tls.
  * Remove brackets against TLS lib when IPv6 addr is used as hostname.
  * Include proxy in connection pool keys.
  * Stop assuming localhost for URLs without host part.
  * Error if body length is less than content-length.
  * Validate header names.
