+# Release Notes – Maven 3.9.3
+
+The Apache Maven team would like to announce the release of Maven 3.9.3.
+
+Maven 3.9.3 is [available for download][0].
+
+Maven is a software project management and comprehension tool. Based on the concept of a project object model (POM), Maven can manage a project's build, reporting, and documentation from a central place.
+
+The core release is independent of plugin releases. Further releases of plugins will be made separately. See the [PluginList][1] for more information.
+
+If you have any questions, please consult:
+
+- the web site: [https://maven.apache.org/][2]
+- the maven-user mailing list: [https://maven.apache.org/mailing-lists.html](/mailing-lists.html)
+- the reference documentation: [https://maven.apache.org/ref/3.9.3/](/ref/3.9.3/)
+
+## Overview About the Changes
+
+* Regression fixes and changes based on user feedback from Maven 3.9.2
+* General performance and other fixes
+
+The full list of changes can be found in our [issue management system][4].
+
+### Notable New Features
+
+* Updated [Eclipse Sisu](https://www.eclipse.org/sisu/) (a Guice based JSR330 container) to latest release. So far used Sisu version was quite old, it supported Java bytecode up to Java 11, limiting all DI managed components (so Mojos, extension and plugin components). This change
+makes possible to create Maven components up to Java 21 bytecode. Naturally, Maven still remains Java 8, so to use plugins, extensions and components compiled into bytecode higher than Java 8, one must use corresponding Java version to run Maven as well.
+* Plugin validation did shake up Maven users community, hence, on users request, they are "toned down". Validation messages are always collected (as before), but default display mode is again "inline" as it was in Maven 3.9.1. Moreover, by default only "project local" messages are displayed to user: issues
+that user can fix by editing the project POM. Plugin non-configuration issues, that can be fixed by corresponding plugin developer only (and requires a release and updating in current project POM) are NOT displayed anymore by default. To enjoy them, one needs explicitly to enable "verbose" mode for plugin
+validation. Furthermore, the precision of warnings and some badly worded messages are fixed.
+* Updated Resolver brings transport related improvements and one interesting new feature: control of checksums per-remote repository.
+
+### Potentially Breaking Core Changes (if migrating from 3.8.x)
+
+* The Maven Resolver transport has changed from Wagon to "native HTTP", see [Resolver Transport guide](/guides/mini/guide-resolver-transport.html).
+* Maven 2.x was auto-injecting an ancient version of `plexus-utils` dependency into the plugin classpath, and Maven 3.x continued doing this to preserve backward compatibility. Starting with Maven 3.9, it does not happen anymore. This change may lead to plugin breakage. The fix for affected plugin maintainers is to explicitly declare a dependency on `plexus-utils`. The workaround for affected plugin users is to add this dependency to plugin dependencies until issue is fixed by the affect [...]
+* Mojos are prevented to bootstrap new instance of `RepositorySystem` (for example by using deprecated `ServiceLocator`), they should reuse `RepositorySystem` instance provided by Maven instead. See [MNG-7471](https://issues.apache.org/jira/browse/MNG-7471).
+* Each line in `.mvn/maven.config` is now interpreted as a single argument. That is, if the file contains multiple arguments, these must now be placed on separate lines, see [MNG-7684](https://issues.apache.org/jira/browse/MNG-7684).
