WordPress 4.5 “Coleman”

Posted April 12, 2016 by Mike Schroder. Filed under Releases.

Version 4.5 of WordPress, named “Coleman” in honor of jazz saxophonist Coleman Hawkins, is available for download or update in your WordPress dashboard. New features in 4.5 help streamline your workflow, whether you’re writing or building your site.

Editing Improvements


Inline Linking

Stay focused on your writing with a less distracting interface that keeps you in place and allows you to easily link to your content.


Formatting Shortcuts

Do you enjoy using formatting shortcuts for lists and headings? Now they’re even more useful, with horizontal lines and <code>.

Customization Improvements


Live Responsive Previews

Make sure your site looks great on all screens! Preview mobile, tablet, and desktop views directly in the customizer.

Custom Logos

Themes can now support logos for your business or brand. Try it out with Twenty Sixteen and Twenty Fifteen in the Site Identity section of the customizer.

Under the Hood

Smart Image Resizing

Generated images now load up to 50% faster with no noticeable quality loss. It’s really cool.

Selective Refresh

The customizer now supports a comprehensive framework for rendering parts of the preview without rewriting your PHP code in JavaScript.

Script Loader Improvements

Better support has been added for script header/footer dependencies. New wp_add_inline_script() enables adding extra code to registered scripts.

Better Embed Templates

Embed templates have been split into parts and can be directly overridden by themes via the template hierarchy.

JavaScript Library Updates

jQuery 1.12.3, jQuery Migrate 1.4.0, Backbone 1.2.3, and Underscore 1.8.3 are bundled.

WordPress 4.5 RC2

Posted April 10, 2016 by Mike Schroder. Filed under Development, Releases.

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 1Beta 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
Release Candidate

Contributor Weekend: Global WordPress Translation Day

Posted April 7, 2016 by Josepha. Filed under Community.

Global WordPress Translation Day is a one-day contributor initiative organised by the WordPress project’s Polyglots team that is dedicated to helping new contributors who would like to translate WordPress in one of the 160 languages WordPress is available in.

Global WordPress Translation Day will be on Sunday, April 24th, starting at 0:00 UTC and will go on for 24 hours covering all time zones.

What are we doing?

  • Live training: A 24h live streaming of tutorials about translating WordPress in different languages and making your code translatable (30min/1h sessions in different languages including a general instruction and specifics for that particular language). The internationalization sessions will be in English. The sessions will be presented by some of the most experienced WordPress translators and internationalization experts. The Schedule can be found on the website.
  • Local translation contributor days: Groups of contributors gather at different locations and work face to face.
  • Local remote translation contributor days: Current translation teams dedicate time and get involved remotely to do orientation for their potential contributors or work with their current translation teams on translating as many strings as they can.

If you organise a local meetup, why not organise a contributor day for translating in your language?

Join us! Read about the initiative and sign up as an organiser.

Can I get involved if I only speak English?

Yes! Even if you only speak English, it would be great to get involved and check out some of the English locale variants – English as spoken in the United Kingdom, Canada, New Zealand, Australia, South Africa. English has many variants across the globe and you can learn about the differences and why it’s important that users have the option to choose a variant during some of our sessions. And if you’re in a funky mood, you can give translating the interface into Emoji a try! Yes, we have a WordPress in Emoji locale!


The polyglots team and the event organisers hang out in #Polyglots in Slack. They will gladly help you out.

Want to follow the code? There’s a development P2 blog and you can track active development in the Trac timeline that often has 20–30 updates per day.
