The new version has been released addressing a bug affecting the functionality of Social Login on Jetpack Comments.
The Jetpack team fixed an issue that came along with the release of Jetpack 6.4. The bug affected visitors attempting to comment by authenticating with Social Login buttons on the Jetpack Comments form.
Jetpack 6.4.2 is a very small yet crucial update and only contained the enhanced functionality of social login for comments. So, we suggest you update the plugin right away and use the latest version to avoid the fatal errors and changes.
Check out the full changelog to know more about the update in Jetpack 6.4.2.
