WordPress 4.5 RC2

The second release candidate for WordPress 4.5 is now available.

We’ve made 91 changes since the first release candidate. RC means we think we’re done, but with millions of users and thousands of plugins and themes, it’s possible we’ve missed something. We hope to ship WordPress 4.5 on Tuesday, April 12, but we need your help to get there.

If you haven’t tested 4.5 yet, now is the time!

Think you’ve found a bug? Please post to the Alpha/Beta support forum. If any known issues come up, you’ll be able to find them here.

To test WordPress 4.5, you can use the WordPress Beta Tester plugin or you can download the release candidate here (zip).

For more information about what’s new in version 4.5, check out the Beta 1, Beta 2, Beta 3, and Beta 4 blog posts.

Developers, please test your plugins and themes against WordPress 4.5 and update your plugin’s Tested up to version in the readme to 4.5. If you find compatibility problems, we never want to break things, so please be sure to post to the support forums so we can figure those out before the final release.

Polyglots, strings are now hard frozen, including the About Page, so you are clear to translate!

A few changes of note since the first release candidate:

Normalized non-slashing of data in the REST API infrastructure. If you use the REST API infrastructure, check out the post on this change.
Customizer settings for widget instances get registered a bit later to give a chance for the widget instances themselves to be registered first. See #36431 for details.
Fixed various cropping issues in the Custom Logo feature and Twenty Fifteen / Twenty Sixteen themes.

Be sure to follow along the core development blog, where you can find the Field Guide for 4.5.

It’s great fun to test
Enjoyment in another
