What's new in HiveMQ Edge 2026.8

HiveMQ Edge 2026.8 establishes Java 25 as the supported runtime, aligning the platform with a Long-Term Support release backed by vendor security and stability commitments through at least 2028 and providing the runtime baseline on which subsequent capacity and performance work will build. Customers deploying the official container image or Helm chart require no action; only deployments using a self-managed Java runtime need to update their JDK ahead of the upgrade.

Java 25 Runtime

What It Is

From 2026.8, HiveMQ Edge runs on Java 25, the current Long-Term Support release of the Java platform. The previous runtime (Java 21) reaches the end of permissive licensing in September 2026, so this upgrade closes a fixed deadline on the books and replaces it with a stable, vendor-supported runtime through 2028 and beyond.

How It Works

If your gateways run from the official HiveMQ Edge container or Helm chart, there is nothing to change — Java 25 has been the embedded runtime since 2026.2, and the chart simply bumps to 2026.8.

If your gateways run on bare-metal servers, virtual machines, or a custom container with a JDK you manage yourselves, install a Java 25 distribution before deploying 2026.8. An older JDK will refuse to start the gateway and report it immediately at startup — no silent half-start, no partially-connected devices.

How It Helps

Java 25 is the current Long-Term Support release of the Java platform, with vendor security and stability support committed through at least 2028. The previous runtime, Java 21, reaches the end of permissive licensing in September 2026; moving to Java 25 now keeps HiveMQ Edge on a fully supported, regularly patched platform and avoids a forced migration later in the year.

Additional Improvements

• Simulation adapter — clearer tag configuration: Static-value and random-value simulation tags are now configured independently rather than through a single combined form. The user interface presents the two tag types as mutually exclusive options, simplifying the construction of commissioning, training, and acceptance-test scenarios.
• Updated protocol stacks: Routine upgrades to the runtime libraries behind OPC UA (Milo), Modbus, the MQTT client, Jackson, and protobuf. These updates incorporate fixes published by the respective protocol communities and keep the gateway aligned with current upstream releases.
• Maintenance and performance: A range of smaller fixes and incremental performance improvements drawn from the operational support of HiveMQ Edge deployments in production environments.
