Once Confluence is on version 5.6.4 (or later versions), the following add-ons will be listed as incompatible with the next versions:

• Applinks Diagnostics Plugin: https://marketplace.atlassian.com/plugins/com.atlassian.applinks.applinks-diagnostics-plugin
• SSL for Confluence: https://marketplace.atlassian.com/plugins/com.atlassian.confluence.plugins.ssl
• Public Announcement Service: https://marketplace.atlassian.com/plugins/com.atlassian.pas
• IM Presence NG Plugin: https://marketplace.atlassian.com/plugins/confluence.extra.impresence2

This is a request to update the version Matrix in Marketplace, so the users can use the plugins without reminders in the instance.
