BREAKING: Upgrading to Kotlin 2.0.0

[lauzadis]

An upcoming release of the AWS SDK for Kotlin will upgrade our dependency on Kotlin to v2.0.0. This version contains a number of binary compatibility breakages and earlier versions of the SDK are not compatible with it.

Release date

This feature will ship with the v1.3.0 release planned for no earlier than 7/29/2024.

What's changing

The Kotlin SDK will be upgrading its dependency on Kotlin to v2.0.0. If you don't depend on different versions of the AWS SDK for Kotlin in the same project, this change should not affect you.

If you do depend on different versions of the AWS SDK for Kotlin in the same project, you will need to make sure they are all upgraded to v1.3.0 together. Versions of the SDK prior to v1.3.0 will no longer be compatible with newer versions.

If you depend on versions of smithy-kotlin separately from the SDK, you will also need to upgrade all of those versions to v1.3.0. Versions of smithy-kotlin prior to v1.3.0 will not be compatible with newer versions of the SDK.

How to migrate

1. Upgrade all of your AWS SDK for Kotlin and smithy-kotlin dependencies to v.1.3.0.
2. Resolve any issues caused by changes in Kotlin v2.0.0. See their “What’s new“ post for more information.
