Performance Enhancements
We’ve improved Jetpack’s performance by making calls to the database more efficient. Essentially, Jetpack is doing less on each page load, making things faster. We’ve also made some changes to Photon and Carousel to load your images faster than ever.
Feature and UI Improvements
Are you familiar with our Secure Sign On module? It allows you to use your WordPress.com log in credentials to register for and sign in to your self-hosted site quickly and securely.
We fully redesigned SSO with improvements that will make it even easier to set up and use on your site. Give it a try by going to Jetpack > Settings in your dashboard, and enabling the SSO module.
Also new in this release are two new Sharing buttons. Now, your readers can share your posts on Telegram and, if they’re using a mobile device, on WhatsApp.
To add these new buttons to your site, go to Settings > Sharing in your dashboard, or access your sharing options in your Manage dashboard!
That’s not all! We also worked on some improvements for the foodies and beer connoisseurs.
- Food bloggers will like our improved
[recipe]shortcode to format and publish recipes. You can find detailed instructions about this shortcode here. - If you are an Untappd user, you might be interested in our new
[untappd-menu]shortcode. To use the shortcode, follow the instructions here.
Security
We’re continuing our efforts to harden Jetpack security and we’ve added extra measures to avoid timing attacks when comparing strings. Thanks to Elliott Stocks who reached out to us about this.
We also improved the WordPress.com connection process for sites using an SSL certificate.
And more!

Lots of nice updates! Excited about the performance improvements.
In the next release can we get JetPack minified with the Javascript and HTLM it uses. Seems like it is always flagged with Google PageSpeed Insights.

We already concatenate and minify CSS, and we will do the same for JavaScript files soon. It won’t happen in Jetpack 4.2, but we’re already working on having this implemented in Jetpack 4.3. You can follow our progress here:

Don’t worry though, Jetpack 4.2 will also come with quite a few performance improvements!

You don’t need to make any changes to Jetpack to implement those changes; you can make those changes in a functionality plugin, or in your theme.
