2.11.0
New
- The built-in
OptionalConverterFactory
is now public to allow installing it before other converters which consume all types (e.g., Moshi, Gson, Jackson, etc.).
Fixed
- Ensure that exceptions thrown from failure to parse method annotations can be observed by multiple threads/callers. Previously only the first caller would see the actual parsing exception and other callers would get a cryptic
ClassCastException
.
2.10.0
New
-
Support using
Unit
as a response type. This can be used for non-body HTTP methods likeHEAD
or body-containing HTTP methods likeGET
where the body will be discarded without deserialization. -
kotlinx.serialization converter!
This was imported from github.com/JakeWharton/retrofit2-kotlinx-serialization-converter/ and remains unchanged from its 1.0.0 release.
The Maven coordinates are
com.squareup.retrofit2:converter-kotlinx-serialization
. -
JAXB 3 converter!
The Maven coordinates are
com.squareup.retrofit2:converter-jaxb3
. -
@Header
,@Headers
, and@HeaderMap
can now set non-ASCII values through theallowUnsafeNonAsciiValues
annotation property. These are not technically compliant with the HTTP specification, but are often supported or required by services. -
Publish a BOM of all modules. The Maven coordinates are
com.squareup.retrofit2:retrofit-bom
. -
Invocation
now exposes the serviceClass<?>
and the instance on which the method was invoked. This disambiguates the source when service inheritence is used. -
A response type keeper annotation processor is now available for generating shrinker rules for all referenced types in your service interface. In some cases, it's impossible for static shrinker rules to keep the entirety of what Retrofit needs at runtime. This annotation processor generates those additional rules. For more info see its README.
Changed
- Add shrinker rules to retain the generic signatures of built-in types (
Call
,Response
, etc.) which are used via reflection at runtime. - Remove backpressure support from RxJava 2 and 3 adapters. Since we only deliver a single value and the Reactive Streams specification states that callers must request a non-zero subscription value, we never need to honor backpressure.
- Kotlin
Retrofit.create
function now has a non-null lower bound. Even if you specified a nullable type before this function would never return null. - Suspend functions now capture and defer all
Throwable
subtypes (not justException
subtypes) to avoid Java'sUndeclaredThrowableException
when thrown synchronously. - Eagerly reject
suspend fun
functions that returnCall<Body>
. These are never correct, and should declare a return type ofBody
directly. - Support for Java 14-specific and Java 16-specific reflection needed to invoke default methods on interfaces have been moved to separate versions of a class through a multi-release jar. This should have no observable impact other than the jar now contains classes which target Java 14 and Java 16 bytecode that might trip up some static analysis tools which are not aware of multi-release jars.
- Parameter names are now displayed in exception messages when available in the underlying Java bytecode.
- Jackson converter now supports binary formats by using byte streams rather than character streams in its implementation. Use the
create(ObjectMapper, MediaType)
overload to supply the value of theContent-Type
header for your format.
Fixed
- Do not include synthetic methods when doing eager validation.
- Use per-method rather than per-class locking when parsing annotations. This eliminates contention when multiple calls are made in quick succession at the beginning of the process lifetime.
