| [#versionless] | ||
| == Streamline feature selection with versionless Jakarta EE, Java EE, and MicroProfile features | ||
|
|
||
| With Open Liberty, you configure only the features at the specific versions that your application needs. This composable design pattern minimizes runtime resource requirements and accelerates application startup times. However, you might not always know which version of a feature is compatible with the rest of your application configuration. In previous releases, determining the correct version typically required a mix of experimentation, guesswork, and digging deep into feature documentation. In 24.0.0.8 and later, versionless features automate version selection, enabling you to focus on application development without worrying about compatibility issues. | ||
|
|
||
| For example, instead of specifying `servlet-6.0` in your `server.xml` file and having to figure out which other feature versions are compatible with Servlet 6.0, you can specify a platform version and `servlet`. The platform that you specify resolves all versionless features to a compatible version. | ||
|
|
||
| The following `server.xml` file configuration uses a Java EE platform of `javaee-8.0` with associated versionless features that are defined for `servlet`, `jpa`, and `jaxrs`: | ||
|
|
||
| [source,xml] | ||
| ---- | ||
| <!-- Enable features --> | ||
| <featureManager> | ||
| <platform>javaee-8.0</platform> | ||
| <feature>servlet</feature> | ||
| <feature>jpa</feature> | ||
| <feature>jaxrs</feature> | ||
| </featureManager> | ||
| ---- | ||
|
|
||
| This example enables versionless MicroProfile features with `microProfile-5.0` specified as the platform element: | ||
|
|
||
| [source,xml] | ||
| ---- | ||
| <!-- Enable features --> | ||
| <featureManager> | ||
| <platform>microProfile-5.0</platform> | ||
| <feature>mpHealth</feature> | ||
| <feature>mpMetrics</feature> | ||
| </featureManager> | ||
| ---- | ||
|
|
||
| Learn more and check out the full collection of available platforms and versionless features in the link:{url-prefix}/docs/latest/reference/feature/versionless-features.html[Open Liberty docs]. Stay tuned for more versionless features and platforms in future releases. | ||

| [#audit] | ||
| == Use the Audit 2.0 feature to avoid generating unnecessary REST Handler records | ||
|
|
||
| The 24.0.0.8 release introduces the link:{url-prefix}/docs/latest/reference/feature/audit-2.0.html[Audit 2.0 feature] (`audit-2.0`). The feature is designed for users who are not using REST Handler applications. | ||
| It provides the same audit records as the Audit 1.0 feature (`audit-1.0`) but it does not generate records for REST Handler applications. | ||
|
|
||
| If you need to keep audit records for REST Handler applications, you can continue to use the Audit 1.0 feature. | ||
|
|
||
| To enable the Audit 2.0 feature in your application, add the following code to your `server.xml` file: | ||
|
|
||
| [source,xml] | ||
| ---- | ||
| <featureManager> | ||
| <feature>audit-2.0</feature> | ||
| </featureManager> | ||
