Announcing Data Center Platform 7.0. Next step to improve our security posture

Appreciated this! I just have a question wish I could get some help from anyone here. As what this post guided, we started to opt-in the platform 6.5 changes by adding the dependency to ensure our application continue work with Confluence 8.8:

<dependencyManagement>
        <dependencies>
            <dependency>
                <groupId>com.atlassian.platform.dependencies</groupId>
                <artifactId>platform-public-api</artifactId>
                <version>${platform.version}</version>
                <type>pom</type>
                <scope>import</scope>
                <exclusions>
                    <exclusion>
                        <groupId>com.atlassian.crowd</groupId>
                        <artifactId>crowd-events</artifactId>
                    </exclusion>
                </exclusions>
            </dependency>
            <dependency>
                <groupId>com.atlassian.platform.dependencies</groupId>
                <artifactId>platform-deprecated-public-api</artifactId>
                <version>${platform.version}</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
        </dependencies>
    </dependencyManagement>

The version of the Confluence we test with the changes is v8.8.0-rc1, we get a org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'txTemplate' error when installing our plugin in, here is the full stacktrace:

The bean that error referring to is this:

<component-import key="txTemplate" interface="com.atlassian.sal.api.transaction.TransactionTemplate"/>

Seems like com.atlassian.sal.api is not accessible at runtime, is anyone have any idea about what’s happening here?

The package marked as CHANGED in the list, could it mean the restriction of com.atlassian.sal.api has changed and is no longer accessible publicly?

Any help would be highly appreciated!
Thanks.
