CHANGELOG.md

Change Log

Version 2.8.1 (2020-03-25)

• Fix: Do not access MethodHandles.Lookup on Android API 24 and 25. The class is only available on Android API 26 and higher.

Version 2.8.0 (2020-03-23)

• New: Add Call.timeout() which returns the okio.Timeout of the full call.
• Fix: Change Call.awaitResponse() to accept a nullable response type.
• Fix: Support default methods on Java 14+. We had been working around a bug in earlier versions of Java. That bug was fixed in Java 14, and the fix broke our workaround.

Version 2.7.2 (2020-02-24)

• Fix: Update to OkHttp 3.14.7 for compatibility with Android R (API 30).

Version 2.7.1 (2020-01-02)

• Fix: Support 'suspend' functions in services interfaces when using 'retrofit-mock' artifact.

Version 2.7.0 (2019-12-09)

This release changes the minimum requirements to Java 8+ or Android 5+. See this blog post for more information on the change.

• New: Upgrade to OkHttp 3.14.4. Please see its changelog for 3.x.
• Fix: Allow service interfaces to extend other interfaces.
• Fix: Ensure a non-null body is returned by Response.error.

Version 2.6.4 (2020-01-02)

• Fix: Support 'suspend' functions in services interfaces when using 'retrofit-mock' artifact.

Version 2.6.3 (2019-12-09)

• Fix: Change mechanism for avoiding UndeclaredThrowableException in rare cases from using yield an explicit dispatch which ensures that it will work even on dispatchers which do not support yielding.

Version 2.6.2 (2019-09-23)

• Fix: Avoid IOExceptions being wrapped in UndeclaredThrowableException in rare cases when using Response<..> as a return type for Kotlin 'suspend' functions.

Version 2.6.1 (2019-07-31)

• Fix: Avoid IOExceptions being wrapped in UndeclaredThrowableException in rare cases.
• Fix: Include no-content ResponseBody for responses created by Response.error.
• Fix: Update embedded R8/ProGuard rules to not warn about nested classes used for Kotlin extensions.

Version 2.6.0 (2019-06-05)

• New: Support suspend modifier on functions for Kotlin! This allows you to express the asynchrony of HTTP requests in an idiomatic fashion for the language.

  @GET("users/{id}")
  suspend fun user(@Path("id") id: Long): User

  Behind the scenes this behaves as if defined as fun user(...): Call<User> and then invoked with Call.enqueue. You can also return Response<User> for access to the response metadata.

  Currently this integration only supports non-null response body types. Follow issue 3075 for nullable type support.

• New: @Tag parameter annotation for setting tags on the underlying OkHttp Request object. These can be read in CallAdapters or OkHttp Interceptors for tracing, analytics, varying behavior, and more.

• New: @SkipCallbackExecutor method annotation will result in your Call invoking its Callback on the background thread on which the HTTP call was made.

• New: Support OkHttp's Headers type for @HeaderMap parameters.

• New: Add Retrofit.Builder.baseUrl(URL) overload.

• Fix: Add embedded R8/ProGuard rule which retains Retrofit interfaces (while still allowing obfuscation). This is needed because R8 running in 'full mode' (i.e., not in ProGuard-compatibility mode) will see that there are no subtypes of these interfaces and rewrite any code which references instances to null.

• Fix: Mark HttpException.response() as @Nullable as serializing the exception does not retain this instance.

• Fix: Fatal errors (such as stack overflows, out of memory, etc.) now propagate to the OkHttp Dispatcher thread on which they are running.

• Fix: Ensure JAX-B converter closes the response body when an exception is thrown during deserialization.

• Fix: Ignore static methods when performing eager validation of interface methods.

• Fix: Ensure that calling source() twice on the ResponseBody passed to a Converter always returns the same instance. Prior to the fix, intermediate buffering would cause response data to be lost.

Version 2.5.0 (2018-11-18)

• New: Built-in support for Kotlin's Unit type. This behaves the same as Java's Void where the body content is ignored and immediately discarded.
• New: Built-in support for Java 8's Optional and CompletableFuture types. Previously the 'converter-java8' and 'adapter-java8' dependencies were needed and explicitly adding Java8OptionalConverterFactory and/or Java8CallAdapterFactory to your Retrofit.Builder in order to use these types. Support is now built-in and those types and their artifacts are marked as deprecated.
• New: Invocation class provides a reference to the invoked method and argument list as a tag on the underlying OkHttp Call. This can be accessed from an OkHttp interceptor for things like logging, analytics, or metrics aggregation.
• New: Kotlin extension for Retrofit which allows you call create passing the interface type only as a generic parameter (e.g., retrofit.create<MyService>()).
• New: Added Response.success overload which allows specifying a custom 2xx status code.
• New: Added Calls.failure overload which allows passing any Throwable subtype.
• New: Minimal R8 rules now ship inside the jar requiring no client configuration in the common case.
• Fix: Do not propagate fatal errors to the callback. They are sent to the thread's uncaught exception handler.
• Fix: Do not enqueue/execute an otherwise useless call when the RxJava type is disposed by onSubscribe.
• Fix: Call RxJavaPlugins assembly hook when creating an RxJava 2 type.
• Fix: Ensure both the Guava and Java 8 Optional converters delegate properly. This ensures that converters registered prior to the optional converter can be used for deserializing the body type.
• Fix: Prevent @Path values from participating in path-traversal. This ensures untrusted input passed as a path value cannot cause you to make a request to an un-intended relative URL.
• Fix: Simple XML converter (which is deprecated) no longer wraps subtypes of RuntimeException or IOException when it fails.
• Fix: Prevent JAXB converter from loading remote entities and DTDs.
• Fix: Correctly detect default methods in interfaces on Android (API 24+). These still do not work, but now a correct exception will be thrown when detected.
• Fix: Report more accurate exceptions when a @QueryName or @QueryMap precedes a @Url parameter.
• Update OkHttp dependency to 3.12.

Version 2.4.0 (2018-03-14)

• New: Retrofit.Builder exposes mutable lists of the added converter and call adapter factories.
• New: Call adapter added for Scala's Future.
• New: Converter for JAXB replaces the now-deprecated converter for Simple XML Framework.
• New: Add Java 9 automatic module names for each artifact corresponding to their root package.
• Fix: Do not swallow Errors from callbacks (usually OutOfMemoryError).
• Fix: Moshi and Gson converters now assert that the full response was consumed. This prevents hiding bugs in faulty adapters which might not have consumed the full JSON input which would then cause failures on the next request over that connection.
• Fix: Do not conflate OkHttp Call cancelation with RxJava unsubscription/disposal. Prior to this change, canceling of a Call would prevent a cancelation exception from propagating down the Rx stream.

Version 2.3.0 (2017-05-13)

• Retrofit now uses @Nullable to annotate all possibly-null values. We've added a compile-time dependency on the JSR 305 annotations. This is a provided dependency and does not need to be included in your build configuration, .jar file, or .apk. We use @ParametersAreNonnullByDefault and all parameters and return types are never null unless explicitly annotated @Nullable.

  Warning: this release is source-incompatible for Kotlin users. Nullability was previously ambiguous and lenient but now the compiler will enforce strict null checks.

• New: Converters added for Java 8's and Guava's Optional which wrap a potentially-nullable response body. These converters still rely on normal serialization library converters for parsing the response bytes into an object.

• New: String converters that return null for an @Query or @Field parameter are now skipped.

• New: The mock module's NetworkBehavior now throws a custom subclass of IOException to more clearly indicate the exception's source.

• RxJava 1.x converter updated to 1.3.0 which stabilizes the use of Completable.

• Fix: Add explicit handling for OnCompleteFailedException, OnErrorFailedException, and OnErrorNotImplementedException for RxJava 1.x to ensure they're correct delivered to the plugins/hooks for handling.

• Fix: NoSuchElementException thrown when unsubscribing from an RxJava 1.x Single.

Version 2.2.0 (2017-02-21)

• RxJava 2.x is now supported with a first-party 'adapter-rxjava2' artifact.
• New: @QueryName annotation allows creating a query parameter with no '=' separator or value.
• New: Support for messages generated by Protobuf 3.0 or newer when using the converter for Google's protobuf.
• New: RxJava 1.x call adapter now correctly handles broken subscribers whose methods throw exceptions.
• New: Add toString() implementations for Response and Result.
• New: The Moshi converter factory now offers methods for enabling null serialization and lenient parsing.
• New: Add createAsync() to RxJava 1.x call adapter factory which executes requests using Call.enqueue() using the underlying HTTP client's asynchronous support.
• New: NetworkBehavior now allows setting an error percentage and returns HTTP errors when triggered.
• HttpException has been moved into the main artifact and should be used instead of the versions embedded in each adapter (which have been deprecated).
• Promote the response body generic type on CallAdapter from the adapt method to the enclosing class. This is a source-incompatible but binary-compatible change which is only relevant if you are implementing your own CallAdapters.
• Remove explicit handling of the now-defunct RoboVM platform.
• Fix: Close response on HTTP 204 and 205 to avoid resource leak.
• Fix: Reflect the canceled state of the HTTP client's Call in Retrofit's Call.
• Fix: Use supplied string converters for the String type on non-body parameters. This allows user converters to handle cases such as when annotating string parameters instead of them always using the raw string.
• Fix: Skip a UTF-8 BOM (if present) when using the converter for Moshi.

Version 2.1.0 (2016-06-15)

• New: @HeaderMap annotation and support for supplying an arbitrary number of headers to an endpoint.
• New: @JsonAdapter annotations on the @Body parameter and on the method will be propagated to Moshi for creating the request and response adapters, respectively.
• Fix: Honor the Content-Type encoding of XML responses when deserializing response bodies.
• Fix: Remove the stacktrace from fake network exceptions created from retrofit-mock's NetworkBehavior. They had the potential to be misleading and look like a library issue.
• Fix: Eagerly catch malformed Content-Type headers supplied via @Header or @Headers.

Version 2.0.2 (2016-04-14)

• New: ProtoConverterFactory.createWithRegistry() method accepts an extension registry to be used when deserializing protos.
• Fix: Pass the correct Call instance to Callback's onResponse and onFailure methods such that calling clone() retains the correct threading behavior.
• Fix: Reduce the per-request allocation overhead for the RxJava call adapter.

Version 2.0.1 (2016-03-30)

• New: Support OkHttp's HttpUrl as a @Url parameter type.
• New: Support iterable and array @Part parameters using OkHttp's MultipartBody.Part.
• Fix: Honor backpressure in Observables created from the RxJavaCallAdapterFactory.

Version 2.0.0 (2016-03-11)

Retrofit 2 is a major release focused on extensibility. The API changes are numerous but solve shortcomings of the previous version and provide a path for future enhancement.

Because the release includes breaking API changes, we're changing the project's package name from retrofit to retrofit2. This should make it possible for large applications and libraries to migrate incrementally. The Maven group ID is now com.squareup.retrofit2. For an explanation of this strategy, see Jake Wharton's post, Java Interoperability Policy for Major Version Updates.

• Service methods return Call<T>. This allows them to be executed synchronously or asynchronously using the same method definition. A Call instance represents a single request/response pair so it can only be used once, but you can clone() it for re-use. Invoking cancel() will cancel in-flight requests or prevent the request from even being performed if it has not already.

• Multiple converters for multiple serialization formats. API calls returning different formats (like JSON, protocol buffers, and plain text) no longer need to be separated into separate service interfaces. Combine them together and add multiple converters. Converters are chosen based on the response type you declare. Gson is no longer included by default, so you will always need to add a converter for any serialization support. OkHttp's RequestBody and ResponseBody types can always be used without adding one, however.

• Call adapters allow different execution mechanisms. While Call is the built-in mechanism, support for additional ones can be added similar to how different converters can be added. RxJava's Observable support has moved into a separate artifact as a result, and support for Java 8's CompletableFuture and Guava's ListenableFuture are also provided as additional artifacts.

• Generic response type includes HTTP information and deserialized body. You no longer have to choose between the deserialized body and reading HTTP information. Every Call automatically receives both via the Response<T> type and the RxJava, Guava, and Java 8 call adapters also support it.

• @Url for hypermedia-like APIs. When your API returns links for pagination, additional resources, or updated content they can now be used with a service method whose first parameter is annotated with @Url.

Changes from beta 4:

• New: RxJavaCallAdapterFactory now supports service methods which return Completable which ignores and discards response bodies, if any.
• New: RxJavaCallAdapterFactory supports supplying a default Scheduler which will be used for subscribeOn on returned Observable, Single, and Completable instances.
• New: MoshiConverterFactory supports creating an instance which uses lenient parsing.
• New: @Part can omit the part name and use OkHttp's MultipartBody.Part type for supplying parts. This lets you customize the headers, name, and filename and provide the part body in a single argument.
• The BaseUrl interface and support for changeable base URLs was removed. This functionality can be done using an OkHttp interceptor and a sample showcasing it was added.
• Response.isSuccess() was renamed to Response.isSuccessful() for parity with the name of OkHttp's version of that method.
• Fix: Throw a more appropriate exception with a message when a resolved url (base URL + relative URL) is malformed.
• Fix: GsonConverterFactory now honors settings on the Gson instance (like leniency).
• Fix: ScalarsConverterFactory now supports primitive scalar types in addition to boxed for response body parsing.
• Fix: Retrofit.callbackExecutor() may now return an executor even when one was not explicitly provided. This allows custom CallAdapter.Factory implementations to use it when triggering callbacks to ensure they happen on the appropriate thread for the platform (e.g., Android).

Version 2.0.0-beta4 (2016-02-04)

• New: Call instance is now passed to both onResponse and onFailure methods of Callback. This aids in detecting when onFailure is called as a result of Call.cancel() by checking Call.isCanceled().
• New: Call.request() returns (optionally creating) the Request object for the call. Note: If this is called before Call.execute() or Call.enqueue() this will do relatively expensive work synchronously. Doing so in performance-critical sections (like on the Android main thread) should be avoided.
• New: Support for the release version of OkHttp 3.0 and newer.
• New: adapter-guava module provides a CallAdapter.Factory for Guava's ListenableFuture.
• New: adapter-java8 module provides a CallAdapter.Factory for Java 8's CompleteableFuture.
• New: ScalarsConverterFactory (from converter-scalars module) now supports parsing response bodies into either String, the 8 primitive types, or the 8 boxed primitive types.
• New: Automatic support for sending callbacks to the iOS main thread when running via RoboVM.
• New: Method annotations are now passed to the factory for request body converters. This allows converters to alter the structure of both request bodies and response bodies with a single method-level annotation.
• Each converter has been moved to its own package under retrofit2.converter.<name>. This prevents type collisions when many converters are simultaneously in use.
• Fix: Exceptions thrown when unable to locate a CallAdapter.Factory for a method return type now correctly list the CallAdapter.Factory instances checked.
• Fix: Ensure default methods on service interfaces can be invoked.
• Fix: Correctly resolve the generic parameter types of collection interfaces when subclasses of those collections are used as method parameters.
• Fix: Do not encode / characters in @Path replacements when encoded = true.

Version 2.0.0-beta3 (2016-01-05)

• New: All classes have been migrated to the retrofit2.* package name. The Maven groupId is now com.squareup.retrofit2. This is in accordance with the Java Interoperability Policy for Major Version Updates. With this change Retrofit 2.x can coexiest with Retrofit 1.x in the same project.
• New: Update to use the OkHttp 3 API and OkHttp 3.0.0-RC1 or newer is now required. Similar to the previous point, OkHttp has a new package name (okhttp3.*) and Maven groupId (com.squareup.okhttp3) which allow it to coexist with OkHttp 2.x in the same project.
• New: String converters allow for custom serialization of parameters that end up as strings (such as @Path, @Query, @Header, etc.). Converter.Factory has a new stringConverter method which receives the parameter type and annotations and can return a converter for that type. This allows providing custom rendering of types like Date, User, etc. to a string before being used for its purpose. A default converter will call toString() for any type which retains the mimics the previous behavior.
• New: OkHttp's Call.Factory type is now used as the HTTP client rather than using the OkHttpClient type directly (OkHttpClient does implement Call.Factory). A callFactory method has been added to both Retrofit.Builder and Retrofit to allow supplying alternate implementations of an HTTP client. The client(OkHttpClient) method on Retrofit.Builder still exists as a convenience.
• New: isExecuted() method returns whether a Call has been synchronously or asynchronously executed.
• New: isCanceled() method returns whether a Call has been canceled. Use this in onFailure to determine whether the callback was invoked from cancellation or actual transport failure.
• New: converter-scalars module provides a Converter.Factory for converting String, the 8 primitive types, and the 8 boxed primitive types as text/plain bodies. Install this before your normal converter to avoid passing these simple scalars through, for example, a JSON converter.
• New: Converter.Factory methods now receive a Retrofit instance which also now has methods for querying the next converter for a given type. This allows implementations to delegate to others and provide additional behavior without complete reimplementation.
• New: @OPTIONS annotation more easily allows for making OPTIONS requests.
• New: @Part annotation now supports List and array types.
• New: The @Url annotation now allows using java.net.URI or android.net.Uri (in addition to String) as parameter types for providing relative or absolute endpoint URLs dynamically.
• New: The retrofit-mock module has been rewritten with a new BehaviorDelegate class for implementing fake network behavior in a local mock implementation of your service endpoints. Documentation and more tests are forthcoming, but the SimpleMockService demonstrates its use for now.
• Fix: Forbid Retrofit's Response type and OkHttp's Response type as the response body type given to a Call (i.e., Call<Response>). OkHttp's ResponseBody type is the correct one to use when the raw body contents are desired.
• Fix: The Gson converter now respects settings on the supplied Gson instance (such as serializeNulls). This requires Gson 2.4 or newer.
• The Wire converter has been updated to the Wire 2.0 API.
• The change in 2.0.0-beta2 which provided the Retrofit instance to the onResponse callback of Callback has been reverted. There are too many edge cases around providing the Retrofit object in order to allow deserialization of the error body. To accommodate this use case, pass around the Retrofit response manually or implement a custom CallAdapter.Factory does so automatically.

Version 2.0.0-beta2 (2015-09-28)

• New: Using a response type of Void (e.g., Call<Void>) will ignore and discard the response body. This can be used when there will be no response body (such as in a 201 response) or whenever the body is not needed. @Head requests are now forced to use this as their response type.
• New: validateEagerly() method on Retrofit.Builder will verify the correctness of all service methods on calls to create() instead of lazily validating on first use.
• New: Converter is now parameterized over both 'from' and 'to' types with a single convert method. Converter.Factory is now an abstract class and has factory methods for both request body and response body.
• New: Converter.Factory and CallAdapter.Factory now receive the method annotations when being created for a return/response type and the parameter annotations when being created for a parameter type.
• New: callAdapter() method on Retrofit allows querying a CallAdapter for a given type. The nextCallAdapter() method allows delegating to another CallAdapter from within a CallAdapter.Factory. This is useful for composing call adapters to incrementally build up behavior.
• New: requestConverter() and responseConverter() methods on Retrofit allow querying a Converter for a given type.
• New: onResponse method in Callback now receives the Retrofit instance. Combined with the responseConverter() method on Retrofit, this provides a way of deserializing an error body on Response. See the DeserializeErrorBody sample for an example.
• New: The MoshiConverterFactory has been updated for its v1.0.0.
• Fix: Using ResponseBody for the response type or RequestBody for a parameter type is now correctly identified. Previously these types would erroneously be passed to the supplied converter.
• Fix: The encoding of @Path values has been corrected to conform to OkHttp's HttpUrl.
• Fix: Use form-data content disposition subtype for @Multipart.
• Fix: Observable and Single-based execution of requests now behave synchronously (and thus requires subscribeOn() for running in the background).
• Fix: Correct GsonConverterFactory to honor the configuration of the Gson instances (such as not serializing null values, the default).

Version 2.0.0-beta1 (2015-08-27)

• New: Call encapsulates a single request/response HTTP call. A call can by run synchronously via execute() or asynchronously via enqueue() and can be canceled with cancel().
• New: Response is now parameterized and includes the deserialized body object.
• New: @Url parameter annotation allows passing a complete URL for an endpoint.
• New: OkHttp is now required as a dependency. Types like TypedInput and TypedOutput (and its implementations), Request, and Header have been replaced with OkHttp types like RequestBody, ResponseBody, and Headers.
• New: CallAdapter (and Factory) provides extension point for supporting multiple execution mechanisms. An RxJava implementation is provided by a sibling module.
• New: Converter (and Factory) provides extension point for supporting multiple serialization mechanisms. Gson, Jackson, Moshi, Protobuf, Wire, and SimpleXml implementations are provided by sibling modules.
• Fix: A lot of things.
• Hello Droidcon NYC 2015!

Version 1.9.0 (2015-01-07)

• Update to OkHttp 2.x's native API. If you are using OkHttp you must use version 2.0 or newer (the latest is 2.2 at time of writing) and you no longer need to use the okhttp-urlconnection shim.
• New: Allow disabling Simple XML Framework's strict parsing.
• New: @Header now accepts a List or array for a type.
• New: @Field and @FieldMap now have options for enabling or disabling URL encoding of names and values.
• Fix: Remove query parameters from thread name when running background requests for asynchronous use.

Version 1.8.0 (2014-11-18)

• Update to RxJava 1.0. This comes with the project's 'groupId' change from com.netflix.rxjava to io.reactivex which is why the minor version was bumped.

Version 1.7.1 (2014-10-23)

• Fix: Correctly log null request arguments for HEADERS_AND_ARGS log level.

Version 1.7.0 (2014-10-08)

• New: RetrofitError's getKind() now disambiguates the type of error represented.
• New: HEADERS_AND_ARGS log level displays parameters passed to method invocation along with normal header list.
• New: @Part and @PartMap now support specifying the Content-Transfer-Encoding of their respective values.
• New: @Path, @Query, and @QueryMap now have options for enabling or disabling URL encoding on names (where appropriate) and values.
• @Header now accepts all object types, invoking String.valueOf when neccesary.
• Attempting to use a @Path replacement block ({name}) in a query parameter now suggested @Query in the exception message.
• Fix: Correct NPE when Content-Type override is specified on requests without a body.

• Fix: MockRestAdapter's RxJava support now correctly schedules work on the HTTP executor, specifically when chaining multiple requests together.
• Experimental RxJava support updated for v0.20.

Version 1.6.1 (2014-07-02)

• Fix: Add any explicitly-specified 'Content-Type' header (via annotation or param) to the request even if there is no request body (e.g., DELETE).
• Fix: Include trailing CRLF in multi-part uploads to work around a bug in .NET MVC 4 parsing.
• Fix: Allow null mock exception bodies and use the success type from the declared service interface.

Version 1.6.0 (2014-06-06)

• New: @Streaming on a Response type will skip buffering the body to a byte[] before delivering.
• When using OkHttp, version 1.6.0 or newer (including 2.0.0+) is now required.
• The absence of a response body and an empty body are now differentiated in the log messages.
• Fix: If set, the RequestInterceptor is now applied at the time of Observable subscription rather than at the time of its creation.
• Fix: Callback subtypes are now supported when using MockRestAdapter.
• Fix: RetrofitError now contains a useful message indicating the reason for the failure.

• Fix: Calling Response#getBody when null body now correctly returns instead of throwing an NPE.
• Experimental RxJava support updated for v0.19.
• The Content-Type and Content-Length headers are no longer automatically added to the header list on the Request object. This reverts erroneous behavior added in v1.5.0. Custom Client implementations should revert to adding these headers based on the TypedInput body of the Request.

Version 1.5.1 (2014-05-08)

• New: @PartMap annotation accepts a Map of key/value pairs for multi-part.
• Fix: MockRestAdpater uses the ErrorHandler from its parent RestAdapter.
• Experimental RxJava support updated for v0.18 and is now lazily initialized.

Version 1.5.0 (2014-03-20)

• New: Support for AppEngine's URL Fetch HTTP client.
• New: Multipart requests of unknown length are now supported.
• New: HTTP Content-Type can be overridden with a method-level or paramter header annotation.
• New: Exceptions from malformed interface methods now include detailed information.
• Fix: Support empty HTTP response status reason.
• If an ErrorHandler is supplied it will be invoked for Callback and Observable methods.
• HTTP PATCH method using HttpUrlConnection is no longer supported. Add the OkHttp jar to your project if you need this behavior.
• Custom Client implementations should no longer set Content-Type or Content-Length headers based on the TypedInput body of the Request. These headers will now be added automatically as part of the standard Request header list.

Version 1.4.1 (2014-02-01)

• Fix: @QueryMap, @EncodedFieldMap, and @FieldMap now correctly detect Map-based parameter types.

Version 1.4.0 (2014-01-31)

• New: @Field now accepts List or arrays for multiple values.
• New: @FieldMap accepts a Map of name/value pairs for form URL-encoded request bodies.
• New: Endpoint replaces Server as the representation of the remote API root. The Endpoints utility class contains factories methods for creating instances. Server and ChangeableServer are now deprecated.
• SimpleXmlConverter and JacksonConverter now have a default constructor.
• Response now includes the URL.
• Fix: Hide references to optional classes to prevent over-eager class verifiers from complaining (e.g., Dalvik).
• Fix: Properly detect and reject interfaces which extend from other interfaces.

Version 1.3.0 (2013-11-25)

• New: Converter module for SimpleXML.
• New: Mock module which allows simulating real network behavior for local service interface implementations. See 'mock-github-client' example for a demo.
• New: RxJava Observable support! Declare a return type of Observable<Foo> on your service interfaces to automatically get an observable for that request. (Experimental API)
• Fix: Use ObjectMapper's type factory when deserializing (Jackson converter).

• Fix: Ensure connection is closed on non-200 responses.

Version 1.2.1 (2013-08-30)

• New: Converter for Wire protocol buffers!

Version 1.2.0 (2013-08-23)

• New: Additional first-party converters for Jackson and Protocol Buffers! These are provided as separate modules that you can include and pass to RestAdapter.Builder's setConverter.
• New: @EncodedPath and @EncodedQuery annotations allow provided path and query params that are already URL-encoded.
• New: @PATCH HTTP method annotation.
• Fix: Properly support custom HTTP method annotations in UrlConnectionClient.
• Fix: Apply RequestInterceptor during method invocation rather than at request execution time.
• Change setDebug to setLogLevel on RestAdapter and RestAdapter.Builder and provide two levels of logging via LogLevel.

Version 1.1.1 (2013-06-25)

• Fix: Ensure @Headers-defined headers are correctly added to requests.
• Fix: Supply reasonable connection and read timeouts for default clients.
• Fix: Allow passing null for a @Part-annotated argument to remove it from the multipart request body.

Version 1.1.0 (2013-06-20)

• Add ErrorHandler for customizing the exceptions which are thrown when synchronous methods return non-200 error codes.
• Properly parse responses which erroneously omit the "Content-Type" header.

Version 1.0.2 (2013-05-23)

  • @Body - Forbidden
  • @Header - Allowed

Version 1.0.1 (2013-05-13)
