Release Notes

Kalix JVM SDKs 1.4.0 Adds support for workflows in Java and Scala Protobuf SDKs, see here. Additionally, this version extends View component to support multiple queries to the same table.

Deprecations introduced in Kalix JVM SDKs 1.4.0

Java and Scala Protobuf SDKs:

Old annotations are deprecated and will be removed in the next major release.

Java SDK:

Kalix JVM SDKs 1.3.8 Adds support for on-startup hook in Java SDK, see here. Introduces ability to require multiple values for a JWT static claim and defining it with a regex pattern, see here. General fixes and improvements.

Kalix JVM SDKs 1.3.7 Fixes and improves the broken Maven Archetypes.

Kalix JVM SDKs 1.3.6 Views' enhancements for when doing aggregations. Ability to declare an on-startup hook which will be triggered automatically on instance startup (currently available for Java/Scala Protobuf SDKs, see here). Support for JWT static claims (see docs).

The kalix container-registry commands have been added to assist in managing your assets in the Kalix Container Registry.

HTTP/1.1 support for kalix commands. The kalix CLI uses gRPC to communicate with many backend Kalix services, which requires HTTP/2. In some corporate environments, decrypting transparent proxies are used which don’t support HTTP/2, preventing the kalix CLI from working. This adds a new option to tell kalix to use grpc-web when communicating with backend services, which works over HTTP/1.1.

Kalix JVM SDKs 1.3.5 Support for JUnit 5. Fix regression introduced in v1.3.4 affecting the use of KalixClient and ComponentClient. General documentation improvements.

kalix local command has been added to assist in running and managing Kalix services locally.

Route validations can now be configured. Routes can be protected by HTTP Basic authentication, and, when using client certificates, client certificate subjects can be validated.

Google Cloud logs and metrics exporters can now be configured. This replaces the old Stackdriver log aggregator support.

Kalix JVM SDKs 1.3.4 Support for mocked Service-to-Service and View subscriptions in Integrations tests (make sure to update your current test kit configuration). New service-level JWT configuration that reduces boilerplate and allows for a deny-by-default policy.

Kalix JVM SDKs 1.3.3 Support for JSON Schema Evolution in Java SDK. Improvements in Workflows and TestKit Mocked Topic.
