Jetpack 6.4 has been released and now is available for download. The new version was released on 7th August and has brought some interesting changes along with it.
The new version, Jetpack 6.4 is available as a general maintenance release and has carried many improvements and bug fixes. It has included alignment fixes for lazy loading images, added flat.io shortcode, simple payment widget updates, and more.
A shortcode for flat.io embeds has been added in 6.4. Flat is a music composition software that provides you with all the tools that you need to make your own sheet music. You can simply paste an embed URL obtained on your flat.io score into the post body to get it working.
On the Simple Payment Widget Updates, Jetpack 6.4 has added a warning for admin users when there are Simple Payment products published on pages/posts or as a Widget and the Simple Payment feature is disabled. Additionally, users of a multi-site installation were experiencing fatal errors coming from the Simple Payment Widget if they deactivated Jetpack while running 6.3. The issue has been fixed in 6.4.
We recommend you to update your Jetpack to the latest version right away to avoid the fatal errors and changes.
