7.6.0 (2026-03-02)

Bugs

• Fix #5292: Cluster() configuration should use tlsServerName
• Fix #7174: (httpclient) Fix HTTP client factory priority - VertxHttpClientFactory (default) now has priority -1, OkHttpClientFactory restored to priority 0
• Fix #7174: (httpclient-vertx-5) Add runtime check for Vert.x 5 classes to provide clear error when Vert.x 4/5 conflict occurs
• Fix #7174: (chaos-tests) Fix classpath conflict when testing with Vert.x 5 HTTP client
• Fix #7415: (java-generator) Fix generic type erasure for array of enums with default values
• Fix #7422: (okhttp) Remove internal API usage and fix deprecated OkHttp 5 calls

• Fix #5756: Use Editable interface instead of reflection to instantiate resource builders
• Fix #7422: bump okhttp from 4.12.0 to 5.3.2
• Fix #7252: call additionalConfig when building Vert.x HTTP clients with VertxHttpClientFactory

Dependency Upgrade

• Fix #7374: bump snakeyaml-engine from 2.10 to 3.0.1

New Features

• Fix #7385: Support for Kubernetes v1.35 (Timbernetes)
• Fix #7174: Added Vert.x 5 HTTP client implementation with improved async handling and WebSocket separation
• Fix #7402: Added Byte code level semver API compatibility report generation using Revapi

Note: Breaking changes

• Fix #5756: Resources edited with visitors must now implement io.fabric8.kubernetes.api.builder.Editable. All model classes provided by the client already implement this interface. User-provided custom resources that use visitor-based editing will need to implement Editable (trivial when a builder already exists).
• Fix #7422: bump okhttp from 4.12.0 to 5.3.2. The versions are binary compatible, but the major version upgrade might cause side effects.

Note: Vert.x HTTP Client Compatibility (Issue #7174)

The kubernetes-httpclient-vertx (Vert.x 4.x) and kubernetes-httpclient-vertx-5 (Vert.x 5.x) modules are mutually exclusive.
They must not be included together in your project dependencies.
Both modules provide an implementation of HttpClient.Factory and use the same io.vertx artifact coordinates but with incompatible major versions.

-Problem*: If both modules are present on the classpath, Maven's dependency resolution may pick Vert.x 4.x JARs while the Vertx5HttpClientFactory is selected at runtime.
This causes NoClassDefFoundError for Vert.x 5-specific classes like io.vertx.core.impl.SysProps.

-Solution*: Ensure your project includes only ONE of these modules:

• kubernetes-httpclient-vertx (default, uses Vert.x 4.x) - included transitively via kubernetes-client
• kubernetes-httpclient-vertx-5 (optional, uses Vert.x 5.x) - requires explicit dependency and exclusion of vertx-4

When using Vert.x 5, exclude the default Vert.x 4 client and set the vertx.version property:

<properties>
  <vertx.version>${vertx5.version}</vertx.version> <!-- or explicit 5.0.7 -->
</properties>
<dependencies>
  <dependency>
    <groupId>io.fabric8</groupId>

      <exclusion>
        <groupId>io.fabric8</groupId>
        <artifactId>kubernetes-httpclient-vertx</artifactId>
      </exclusion>
    </exclusions>
  </dependency>
