Jetpack 3.9.3 and 3.9.4 are now available. Although 3.9.3 is billed as a “maintenance and compatibility release,” there are a number of significant changes and improvements that make this an important release.
WordPress 4.5 will introduce native support for a theme logo. This will render Jetpack’s site logo feature obsolete. The 3.9.3 release of the plugin adds compatibility with WordPress 4.5 by ensuring that sites use core’s implementation for custom logos instead.
According to Konstantin Obenland in a recent post on make/core, “Jetpack will do a migration behind the scenes to work with it out of the box.” He also said that WordPress core’s new custom logo feature will use Selective Refresh, which means that the preview will load instantly after the image has been uploaded.
Notable enhancements in this release include:
- When using Carousel and Photon together, Jetpack will now link to the Photon version of full-sized images
- Performance improvements to Comments, Infinite Scroll, Markdown, Publicize, Sitemaps, and the Subscription widget
- Infinite Scroll: Introduced a later filter for settings
- New filters in the Top Posts Widget code

The release also fixes an annoying bug in the Comments module that would reload the page when clicking ‘Reply.’
Jetpack 3.9.4 was released right on the heels of 3.9.3 to fix an issue where some comments were being displayed incorrectly. The problem was significant enough to push out an additional release right away.
Updating to the latest version of Jetpack will help your site work seamlessly with WordPress 4.5 when it is released the week of April 12. Check out the full changelog for both releases to see all of the enhancements and bug fixes.
