Executive summary

I read the Reactor Kotlin Extensions v1.3.3 release, which is now part of Release Train 2025.0.8 and 2026.0.0-RC1. This release primarily updates the Reactor Core dependency to v3.8.8 and the Reactor Addons dependency to v3.6.2.

Problems addressed

These dependency updates keep Reactor Kotlin Extensions aligned with the other Reactor components used in an application. For engineers using Reactor Kotlin Extensions alongside Reactor Core and Reactor Addons, this release reduces the need to manage dependency versions manually or encounter version mismatches.

Key features and code examples

No new API features are described in the v1.3.3 release notes. The changes mentioned are the following dependency updates:

  • Reactor Core: v3.8.8
  • Reactor Addons: v3.6.2

This example only illustrates how to define the Reactor Kotlin Extensions dependency in Gradle:

dependencies {
    implementation("io.projectreactor.kotlin:reactor-kotlin-extensions:1.3.3")
}

Impact and upgrade notes

When upgrading to 1.3.3, projects can follow the Reactor Core and Reactor Addons version changes included in this release. The release is also part of Release Train 2025.0.8 and 2026.0.0-RC1, allowing teams that follow a release train to plan to use consistent versions.

The release notes do not include any API changes, new flags, or additional compatibility details. A complete comparison of the changes is available in the v1.3.2...v1.3.3 range.
