Jetpack 5.5 Removes Syntax Highlighting and Gallery Widget for Compatibility with Upcoming WordPress 4.9 Release

Jetpack 5.5 was released yesterday with several important changes that ensure the plugin is compatible with the upcoming WordPress 4.9 release scheduled for November 14.

    1. Spam protection is plugin territory, and there a many plugins far better than Akismet at combating spam.

      In fact akismet is plain dangerous as it gives false positives.


  2. To clarify, the Press This button is removed if you’re running 4.9 and do not have the separate plugin. If you do have the new Press This plugin, it’ll keep chugging along just fine.
