## New features and improvements

-   The Java Hybrid Agent: offering a "best-of-both-worlds" experience by combining New Relic’s deep visibility with [OpenTelemetry API compatibility](https://docs.newrelic.com/docs/apm/agents/manage-apm-agents/opentelemetry-api-support/). This release includes comprehensive support for the OpenTelemetry Tracing, Metrics, and Logs APIs, as well as standalone library and native framework instrumentation. Key enhancements like Span Links and Events on Spans are now available, ensuring seamless interoperability in mixed-mode environments.

## Update to latest version [#procedures]

To identify which version of the Java agent you're currently using, run `java -jar newrelic.jar -v`. Your Java agent version will be printed to your console.

Then, to update to the latest Java agent version:

1.  Back up the **entire** [Java agent root directory](https://docs.newrelic.com/docs/agents/manage-apm-agents/troubleshooting/find-agent-root-directory#java-agent) to another location. Rename that directory to `NewRelic_Agent#.#.#`, where `#.#.#` is the agent version number.
2.  [Download the agent.](https://docs.newrelic.com/docs/release-notes/agent-release-notes/java-release-notes).
3.  Unzip the new agent download file, then copy `newrelic-api.jar` and `newrelic.jar` into the original [Java agent root directory](https://docs.newrelic.com/docs/agents/manage-apm-agents/troubleshooting/find-agent-root-directory#java-agent).
4.  Compare your old `newrelic.yml` with the newly downloaded `newrelic.yml` from the zip, and [update the file if needed](#diff).
5.  Restart your Java dispatcher.

If you experience issues after the Java agent update, restore from the backed-up New Relic agent directory.

## Update agent config differences [#diff]

We add new settings to `newrelic.yml` as we release new versions of the agent. You can use `diff` or another diffing utility to see what's changed, and add the new config settings to your old file. Make sure not to overwrite any customizations you've made to the file, such as your license key, app name, or changes to default settings.

For example, if you `diff` the default `newrelic.yml` files for Java agent versions 7.10.0 and 7.11.0, the results printed to the console will be like:

```yaml
➜ diff newrelic_7.10.0.yml newrelic_7.11.0.yml
...
107a108,119
>       # Whether the log events should include context from loggers with support for that.
>       context_data:
>
>         # When true, application logs will contain context data.
>         enabled: false
>
>         # A comma separated list of attribute keys whose values should be sent to New Relic.
>         #include:
>
>         # A comma separated list of attribute keys whose values should not be sent to New Relic.
>         #exclude:
>
125a138
>
128c141
<     enabled: false
---
>     enabled: true
...
```

In this example, these lines were added to the default `newrelic.yml` in Java agent version 7.11.0. If you're moving to 7.11.0 or higher, you should add these new lines to your original `newrelic.yml`.

## Support statement:

-   New Relic recommends that you upgrade the agent regularly to ensure that you're getting the latest features and performance benefits. Additionally, older releases will no longer be supported when they reach [end-of-life](https://docs.newrelic.com/docs/using-new-relic/cross-product-functions/install-configure/notification-changes-new-relic-saas-features-distributed-software/).
