+# Release Notes &#x2013; Maven 3.9.10
+
+The Apache Maven team would like to announce the release of Maven 3.9.10.
+
+Maven 3.9.10 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/3.9.10/](/ref/3.9.10/)
+
+## Overview About the Changes
+
+Regression fixes and other improvements from Maven 3.9.9. All users already on 
Maven 3.9.x are advised to upgrade.
+
+The majority of fixed issues are bug and regression fixes for user reported 
problems.
+
+This release updates Resolver to version 
[1.9.23](https://issues.apache.org/jira/secure/ReleaseNote.jspa?projectId=12320628&version=12354989).
+
+When running a build using Java 24 with an earlier version of Maven, there 
were a lot of errors and warnings,
+because many dependencies were not compatible with a Java 24 runtime.
+
+In Maven 3.9.10 those got updated, resulting in Maven 3.9.10 now has a far 
better support if you want to run your builds on Java 24.
+
+**Note:** Maven 3.9.10 still only requires Java 8 to execute.
+
+The full list of changes can be found in our [issue management system][4].
+
+### Known issues ###
+
+- [MNG-8760](https://issues.apache.org/jira/browse/MNG-8760) - warning about 
using terminally deprecated method in guice on JDK 24
+
+### 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).
+* System and user properties handling cleanup, see 
[MNG-7556](https://issues.apache.org/jira/browse/MNG-7556). As a consequence, 
this may introduce breakage in environments where the user properties were used 
to set system properties or other way around, for example see 
[MNG-7887](https://issues.apache.org/jira/projects/MNG/issues/MNG-7887).
+* Plugins and extensions used by your build are checked against Maven 
supported APIs and conventions: this "plugin validation" may report WARNINGs at 
the end of your build. See [plugin validation 
documentation](../../guides/plugins/validation/) to better understand what to 
do when your build suffers from such warnings.
