Changes

API Deprecations

Developer note: Additional API deprecation advisories and guidance have been added in each of the 0.41.X releases. Please build your application with the latest 0.41.X release and carefully review the deprecation warnings reported and associated suggestions. Changes to applications may be required for compatibility with future versions of ServiceTalk beyond the API compatible 0.41.X series. While there are many deprecations for planned future API changes, most applications should require few changes as the most significant changes are to internal or specialized APIs. If you have concerns or expect problems related to any of the API deprecations please report these as an issue.

0.42.11

Changes

This is a minor maintenance release appropriate for all ServiceTalk users that contains several useful improvements and bug fixes. This release is expected to be a "drop-in" replacement for all prior 0.42.X releases.

The 0.41.x branch is now EOL. Please plan your migrations accordingly, and let us know if you have any questions. The recommended path is:

1. Update to the latest version of 0.41.x (https://github.com/apple/servicetalk/releases/tag/0.41.16)
2. Resolve all deprecations. All deprecations include javadocs explaining the recommended replacement approach. The javadocs can pulled by your IDE and also viewable on the 0.41 docs website.
3. Update to latest version of 0.42.x (see https://github.com/apple/servicetalk/releases - currently this release, 0.42.11)

API Deprecations

• 5565f32 - Add default implementations for deprecated methods (#2235) - this helps users to start migrating off interface methods that was marked as @Deprecated in previous releases

New Features

• bff3378 - Add dependencies BOM (#2210)
  • ServiceTalk now provides two BOM (Bill of Materials) files each with slightly different purposes; servicetalk-bom and servicetalk-dependencies. BOM files allow separation of dependency management and version management; a BOM specifies only component versions, not dependencies. Centralizing the management of versions to a single file greatly reduces the maintenance burden for updating to new versions and improves consistency because all references to a dependency will use the same version. The BOM files define the versions of modules which might be included as dependencies, but do not
    include the module as a dependency. Later when the module is included as a dependency, the dependency is specified without including a version and the version specified in the BOM is used.
    The servicetalk-bom BOM includes version information all ServiceTalk modules; version selection for external non-ServiceTalk dependencies is done in individual modules. The servicetalk-dependencies BOM extends the servicetalk-bom by also defining specific versions to be used for the external modules ServiceTalk depends upon. Unless your application requires different versions of these same dependencies then using the servicetalk-dependencies BOM is the most convenient way to ensure that a tested and supported set of modules is used or building and running the application. The servicetalk-dependencies BOM should be preferred whenever possible. Using the servicetalk-bom may be easier when your application wishes to do more complete management of external dependencies, or you wish to include ServiceTalk as an enforcedPlatform, but do not want the external dependencies to be included in that constraint.
    To override a specific dependency version with your application's required version you can use something like the following in your build.gradle:

implementation(platform("io.servicetalk:servicetalk-dependencies:$servicetalkVersion"))

// Overrides the default Netty BOM version imported by ServiceTalk with a specific version
implementation(enforcedPlatform("io.netty:netty-bom")) {
    version {
        strictly '4.1.76.Final'
    }
}
// Overrides the default Jackson databind version with a specific version
implementation ("com.fasterxml.jackson.core:jackson-databind") {
    version {
        strictly '2.13.2.1'
    }
}

0.42.8

Changes

This is a minor maintenance release appropriate for all ServiceTalk users that contains several bug fixes and improvements.

API deprecation

• b92caff - Deprecate HttpClients.forMultiAddressUrl(ServiceDiscoverer) (#2132)
  • Instead, MultiAddressHttpClientBuilder#initializer(SingleAddressInitializer) should be used to override ServiceDiscoverer using SingleAddressHttpClientBuilder#serviceDiscoverer(ServiceDiscoverer).
• a452927 - Deprecated PartitionedHttpClientBuilder and partition client APIs (#2131)
  • PartitionedHttpClientBuilder is hard to use because it requires implementation of a special ServiceDiscoverer that we do not provide OOTB. We are unaware of anyone using this feature, but if there are any users they should consider ClientGroup as an alternative or reach out to us to provide more context why the PartitionedHttpClientBuilder is required.
• 9c3ed5a - grpc-protoc ServiceFactory.Builder #addService(BlockingService) -> #addBlockingService(BlockingService) (#2143)
  • The existing overloaded method required casting to disambiguate calls or implied compiler warnings when the argument was a lambda. We added a specific method for the blocking service argument to improve the API.

New features
