Add a <repositories> section to microsphere-spring-boot-parent/pom.xml registering the Spring Portfolio milestone repository (id: spring-milestone, url: https://repo.spring.io/milestone). This enables resolving Spring milestone artifacts from the parent POM.

Update maven-publish workflow to generate release notes via a Copilot/Models API step. Adds limited permissions (contents: read for build and models: read for the publish job), a Python-based step that collects commits since the previous tag, calls the model to produce concise markdown release notes, appends them to release-notes.md and writes /tmp/current-release-notes.md for the release step. The Create Release step now uses --notes-file and the job also stages release-notes.md so it gets committed after publishing.

Avoid a direct compile-time dependency on Micrometer by replacing @ConditionalOnBean(MeterRegistry.class) with @ConditionalOnBean(type = METER_REGISTRY_CLASS_NAME). Added a string constant METER_REGISTRY_CLASS_NAME (with javadoc) and removed the MeterRegistry import so the conditional is resolved by class name at runtime.

Import MeterRegistry and add assertions in ActuatorAutoConfigurationTest to verify the METER_REGISTRY_CLASS_NAME constant equals the expected fully-qualified name ("io.micrometer.core.instrument.MeterRegistry") and matches MeterRegistry.class.getName(). This strengthens the test by ensuring the constant correctly references the MeterRegistry class name.

Update README: bump branch table versions for 0.2.x and 0.1.x to 0.2.11 and 0.1.11, respectively. Apply minor formatting fixes (adjust blank lines around badges and code blocks, and wrap the 'Before you log a bug' line) to improve readability.

Delete the <repositories> section from microsphere-spring-boot-parent/pom.xml, removing the spring-milestone repository entry (id: spring-milestone, url: https://repo.spring.io/milestone). This cleans up the parent POM to avoid relying on the Spring milestone repository during builds.

Remove the `permissions: contents: read` block from the build job in the maven-publish workflow. This simplifies the workflow by relying on repository/default permissions instead of an explicit read permission; no other functional changes were made.

Add explicit GitHub Actions permissions block to the Maven workflow, granting read-only access to repository contents. This limits the workflow's token scope and ensures the job has the necessary read access for checkout and related steps.

Give the build job read access to repo contents and improve release notes generation. The AI prompt was expanded to include more structured sections (New Features, Bug Fixes, Documentations, Dependency Updates, Test Improvements, Build and Workflow Enhancements, Other Changes). A Full Changelog link is now generated and appended to the repository NOTES file and the temporary release notes file. Also normalize newlines and use the raw inputs.revision (no implicit "v" prefix) when checking/creating GitHub releases, plus small whitespace/end-of-file fixes.

Change .mvn/wrapper/maven-wrapper.properties to point to Apache's official distribution URL and upgrade the Maven binary from 3.9.9 to 3.9.14 (dlcdn.apache.org). This ensures the wrapper fetches the official Apache Maven 3.9.14 release instead of the previous mirror.

Update the parent POM version from 0.2.6 to 0.2.7 to pick up the latest changes from io.github.microsphere-projects:microsphere-build (build fixes/dependency updates).

Update the <microsphere-spring.version> property in the parent POM from 0.1.9 to 0.1.11 so child modules use the newer microsphere-spring release.

Bump Maven distribution from 3.9.14 to 3.9.15 and update the wrapper distributionUrl to use the Maven Aliyun mirror in .mvn/wrapper/maven-wrapper.properties. This ensures the project uses Maven 3.9.15 and can fetch the binary from an alternate mirror.

Update .mvn/wrapper/maven-wrapper.properties to point distributionUrl to repo1.maven.org (Maven Central) instead of the previous aliyun mirror. Ensures the Maven wrapper downloads the official Apache Maven distribution from Maven Central.

Reduce the GitHub Actions build matrix to Java 8 and 11 and add strategy.max-parallel: 7 to cap concurrent jobs. This lowers CI resource usage and shortens run time by removing additional Java versions and limiting parallelism.

Update microsphere-spring.version in microsphere-spring-boot-parent/pom.xml from 0.1.11 to 0.1.13 to pick up the latest microsphere-spring fixes and improvements.

Delete exclusion entries for org.apache.zookeeper:zookeeper and org.apache.curator (curator-recipes, curator-test) from the io.github.microsphere-projects:microsphere-spring-test test dependency in pom.xml. This allows the previously excluded Curator/Zookeeper test artifacts to be pulled in transitively and available on the test classpath.

Update <microsphere-spring.version> from 0.1.13 to 0.1.14 and remove the junit-bom import from dependencyManagement. Keeps Spring Boot dependency imports intact; no other functional changes.

Add an import for org.junit:junit-bom to the parent POM's dependencyManagement, using ${junit-jupiter.version} to centrally manage JUnit/Jupiter dependency versions across modules. This ensures consistent test dependency versions alongside the existing Spring Boot BOM imports.

Replace the CURRENT enum initialization to use Version.ofVersion(SpringBootVersion.class) instead of parsing the runtime version string. Adds a static import for ofVersion and switches from org.springframework.boot.SpringBootVersion.getVersion() to class-based resolution, making version detection more robust and consistent with Version utilities.

Include ActuatorAutoConfigurationTest.class in the classes arrays for the MeterRegistryPresent and MeterRegistryAbsent @SpringBootTest cases so the test class is loaded into the application context during those tests. This ensures the test's configuration/beans are available when running the actuator-related test scenarios.

Replace MockEnvironment.setProperty with withProperty in SpringApplicationUtilsTest.testGetLoggingLevel to set the logging level. This updates the test to use the current MockEnvironment API (avoids deprecated call and supports fluent usage).

Expand the GitHub Actions maven-build workflow matrix to include JDK 17, 21, and 25 in addition to existing 8 and 11. This updates CI to build and test the project against newer Java releases to ensure compatibility.
