Spring Boot 2.7.0 M2 Release Notes
As OkHttp 3 is no longer being maintained, Spring Boot 2.7 has upgraded to OkHTTP 4.
As part of this upgrade, the property used to control OkHttp’s version has changed from okhttp3.version to okhttp.version.
OkHttp 4 is intended to be backwards compatible with OkHttp 3.
If this is not the case in your application or wish to continue using OkHttp 3 for another reason, configure the okttp.version property in your build.
Separate dependency management for netty-tcnative has been removed in favor of the dependency management provided by Netty’s bom.
This ensures that the version of netty-tcnative will align with the version that Netty uses by default.
As a result of this change, the netty-tcnative.version property can no longer be used to override the version of netty-tcnative.
The version can still be overridden by providing your own dependency management but it is recommended that it remains aligned with Netty’s default version.

Tip

Check the configuration changelog for a complete overview of the changes in configuration. |
If you are using opaque token introspection in your OAuth2 resource server, the auto-configured introspector no longer requires a dependency on com.nimbusds:oauth2-oidc-sdk.
Depending on other usages of the SDK, you may be able to remove the dependency from your application.
If you have created your own auto-configurations, you should move the registration from spring.factories to a new file named META-INF/spring/org.springframework.boot.autoconfigure.AutoConfiguration.imports. Each line contains the fully qualified name of the auto-configuration. See the included auto-configurations for an example.
For backwards compatibility, entries in spring.factories will still be honored.
A new @AutoConfiguration annotation has been introduced. It should be used to annotate top-level auto-configuration classes that are listed in the new META-INF/spring/org.springframework.boot.autoconfigure.AutoConfiguration.imports file, replacing @Configuration. Configuration classes that are nested within or imported by an @AutoConfiguration class should continue to use @Configuration as before.
For your convenience, @AutoConfiguration also supports auto-configuration ordering via the after, afterNames, before and beforeNames attributes. This can be used as a replacement for @AutoConfigureAfter and @AutoConfigureBefore.
If you have created your own test-slices, you should move the registration from spring.factories to the new place under META-INF/spring/<name of your test slice annotation>.imports. The format is the same as the new file described in the "Auto-configuration location" section, see above.
Support for specifying a username for authenticating to Sentinel(s) has been added using the spring.redis.sentinel.username property.
Spring Boot 2.7.0-M2 moves to new versions of several Spring projects:
