Turn off "X New Jetpack Modules" notifications?

I also find this annoying, but have not been able to figure out how to stop it. They don’t go away eventually, at least not in my case.

Same here. My current solution is to simply hide them with some admin-side CSS:

.toplevel_page_jetpack .update-plugins {
    display: none;
}

This does the trick for me ??

For the record, my custom admin.css styles get loaded this way, from functions.php

function custom_admin_head() {
        echo '<link rel="stylesheet" type="text/css" href="' .get_bloginfo('template_directory').'/admin/admin.css">';
}
add_action('admin_head', 'custom_admin_head');

I discovered this issue with Omnisearch. And the left over notification bubble is really annoying.

I found that modifying First Introduced value in the header of the module, the bubble goes away. I changed from 2.3 to 2.2.

Looking for another fix, though ??

Amazing!
MCJ is just a handful of lines of code, and I can’t understand how the heck it blocks the auto-activation of new modules.

I dug into Jetpack’s code and looks like there’s no point of entry to modify the 'introduced' value (read from the module file header) for the Available Modules.

Guess CSS is the easiest (and maybe only) way for now. Here a shorter version from Manuel’s example:

add_action('admin_head', 'custom_admin_head');
function custom_admin_head() {
        echo '<style type="text/css">.toplevel_page_jetpack .update-plugins {display: none;}</style>';
}

Even shorter for PHP 5.3

add_action('admin_head', function () {
	echo '<style type="text/css">.toplevel_page_jetpack .update-plugins {display: none;}</style>';
});
