 ## Caveats
 
-### ALPN support
-
-ALPN negotiation is required for "auto" HTTP/2 "https" requests. This is available in ruby since version 2.3 .
-
-### Known bugs
-
-* Doesn't work with ruby 2.4.0 for Windows (see [#36](https://gitlab.com/os85/httpx/issues/36)).
-* Using `total_timeout` along with the `:persistent` plugin [does not work as you might expect](https://gitlab.com/os85/httpx/-/wikis/Timeouts#total_timeout).
-
 ## Versioning Policy
 
 Although 0.x software, `httpx` is considered API-stable and production-ready, i.e. current API or options may be subject to deprecation and emit log warnings, but can only effectively be removed in a major version change.

+# 1.0.0
+
+## Breaking changes
+
+* the minimum supported ruby version is 2.7.0 .
+* The default support for IDNA 2003 has been removed. If you require this feature, install the [idnx gem](https://github.com/HoneyryderChuck/idnx), which `httpx` automatically integrates with when available.
+* `:total_timeout` option has been removed (no session-wide timeout supported, use `:request_timeout`).
+* `:read_timeout` and `:write_timeout` are now set to 60 seconds by default, and preferred over `:operation_timeout`;
+  * the exception being in the `:stream` plugin, as the response is theoretically endless (so `:read_timeout` is unset).
+* The `:multipart` plugin is removed, as its functionality and API are now loaded by default.
+* The `:compression` plugin is removed, as its functionality and API are now loaded by default.
+  * `:compression_threshold_size` was removed (formats in `"content-encoding"` request header will always encode the request body).
+  * the new `:compress_request_body` and `:decompress_response_body` can be set to `false` to (respectively) auto-compress passed input body, or decompress the response body.
+* `:retries` plugin: the `:retry_on` condition will **not** replace default retriable error checks, it will now instead be triggered only if the retriable error checks do not find anything.
+
+### plugins
+
+* `:authentication` plugin becomes `:auth`.
+  * `.authentication` helper becomes `.authorization`.
+* `:basic_authentication` plugin becomes `:basic_auth`.
+  * `:basic_authentication` helper is removed.
+* `:digest_authentication` plugin becomes `:digest_auth`.
+  * `:digest_authentication` helper is removed.
+* `:ntlm_authentication` plugin becomes `:ntlm_auth`.
+  * `:ntlm_authentication` helper is removed.
+* OAuth plugin: `:oauth_authentication` helper is rename to `:oauth_auth`.
+* `:compression/brotli` plugin becomes `:brotli`.
+
+### Support removed for deprecated APIs
+
+* The deprecated `HTTPX::Client` constant lookup has been removed (use `HTTPX::Session` instead).
+* The deprecated `HTTPX.timeout({...})` function has been removed (use `HTTPX.with(timeout: {...})` instead).
+* The deprecated `HTTPX.headers({...})` function has been removed (use `HTTPX.with(headers: {...})` instead).
+* The deprecated `HTTPX.plugins(...)` function has been removed (use `HTTPX.plugin(...).plugin(...)...` instead).
+* The deprecated `:transport_options` option, which was only valid for UNIX connections, has been removed (use `:addresses` instead).
+* The deprecated `def_option(...)` function, previously used to define additional options in plugins, has been removed (use `def option_$new_option)` instead).
+* The deprecated `:loop_timeout` timeout option has been removed.
+* `:stream` plugin: the deprecated `HTTPX::InstanceMethods::StreamResponse` has been removed (use `HTTPX::StreamResponse` instead).
+* The deprecated usage of symbols to indicate HTTP verbs (i.e. `HTTPX.request(:get, ...)` or `HTTPX.build_request(:get, ...)`) is not supported anymore (use the upcase string always, i.e. `HTTPX.request("GET", ...)` or `HTTPX.build_request("GET", ...)`, instead).
+* The deprecated `HTTPX::ErrorResponse#status` method has been removed (use `HTTPX::ErrorResponse#error` instead).
+
+### dependencies
+
+* `:datadog` adapter only supports `ddtrace` gem 1.x or higher.
+* `:faraday` adapter only supports `faraday` gem 1.x or higher.
+
+### chore
+
+* `:grpc` plugin: connection won't buffer requests before HTTP/2 handshake is commpleted, i.e. works the same as plain `httpx` HTTP/2 connection establishment.
+  * if you are relying on this, you can keep the old behavior this way: `HTTPX.plugin(:grpc, http2_settings: { wait_for_handshake: false })`.
