5.2.0

• Make LogInterceptor prints in DEBUG mode (when the assertion is enabled) by default.
• Deprecate DioError in favor of DioException.
• Fix IOHttpClientAdapter.onHttpClientCreate Repeated calls

5.1.2

• Allow FormData to send a null entry value as an empty string.

5.1.1

• Revert changes to CancelToken.cancel() behavior, as a result the DioError provided by the CancelToken.cancelError does not contain useful information when the token was not used with a request.
• Fix wrong ListFormat being used for comparison during encoding of FormData and application/x-www-form-urlencoded, resulting in potential wrong output encoding for ListFormat.multi and ListFormat.multiCompatible since Dio 4.0.x.

• A platform independent HttpClientAdapter can now be instantiated by doing dio.httpClientAdapter = HttpClientAdapter();.

• Support Content-Disposition header case sensitivity.

Breaking Changes

• The default charset utf-8 in Headers content type constants has been removed.
• BaseOptions.setRequestContentTypeWhenNoPayload has been removed.
• Improve DioErrors. There are now more cases in which the inner original stacktrace is supplied.
• HttpClientAdapter must now be implemented instead of extended.

3.0.0

New features

• Support Flutter Web.
• Extract CookieManager into a separate package（No need for Flutter Web）.
• Provides HTTP/2.0 HttpClientAdapter.

Change List

• Options.cookies

• Options.connectionTimeout ；We should config connection timed out in BaseOptions. For keep-alive reasons, not every request requires a separate connection。

• Options.followRedirects、Options.maxRedirects、Response.redirects don't make sense in Flutter Web，because redirection can be automatically handled by browsers.

• FormData.from，use FormData.fromMap instead.

• Delete Formdata.asBytes()、Formdata.asBytesAsync() , use Formdata.readAsBytes() instead.

• Delete UploadFileInfo class， MultipartFile instead.

• The return type of Interceptor's callback changes from FutureOr<dynamic> to Future. The reason is here.

• The type of Response.headers changes from HttpHeaders to Headers, because HttpHeaders is in "dart:io" library which is not supported in Flutter Web.
