A minor build migration is needed when updating to Kalix JVM SDK 1.5.0. See the migration guide here.

Some deprecated APIs have been removed in Kalix JVM SDKs 1.5.0. Please refer to the migration guide here for more details.

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.

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.
