Version 4.0 of WordPress, named “Benny” in honor of jazz clarinetist and bandleader Benny Goodman, is available for download or update in your WordPress dashboard. While 4.0 is just another number for us after 3.9 and before 4.1, we feel we’ve put a little extra polish into it. This release brings you a smoother writing and management experience we think you’ll enjoy.

Introducing WordPress 4.0 "Benny"

▶

Manage your media with style

Explore your uploads in a beautiful, endless grid. A new details preview makes viewing and editing any amount of media in sequence a snap.

Working with embeds has never been easier

Paste in a YouTube URL on a new line, and watch it magically become an embedded video. Now try it with a tweet. Oh yeah — embedding has become a visual experience. The editor shows a true preview of your embedded content, saving you time and giving you confidence.

We’ve expanded the services supported by default, too — you can embed videos from CollegeHumor, playlists from YouTube, and talks from TED. Check out all of the embeds that WordPress supports.

Focus on your content

Writing and editing is smoother and more immersive with an editor that expands to fit your content as you write, and keeps the formatting tools available at all times.

Finding the right plugin

There are more than 30,000 free and open source plugins in the WordPress plugin directory. WordPress 4.0 makes it easier to find the right one for your needs, with new metrics, improved search, and a more visual browsing experience.

The Ensemble

This release was led by Helen Hou-Sandí, with the help of these fine individuals. There are 275 contributors with props in this release, a new high. Pull up some Benny Goodman on your music service of choice, as a bandleader or in one of his turns as a classical clarinetist, and check out some of their profiles:

The first release candidate for WordPress 4.0 is now available!

In RC 1, we’ve made refinements to what we’ve been working on for this release. Check out the Beta 1 announcement post for more details on those features. We hope to ship WordPress 4.0 next week, but we need your help to get there. If you haven’t tested 4.0 yet, there’s no time like the present. (Please, not on a production site, unless you’re adventurous.)

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

To test WordPress 4.0 RC1, try the WordPress Beta Tester plugin (you’ll want “bleeding edge nightlies”). Or you can download the release candidate here (zip). If you’d like to learn more about what’s new in WordPress 4.0, visit the awesome About screen in your dashboard ( → About in the toolbar).

Developers, please test your plugins and themes against WordPress 4.0 and update your plugin’s Tested up to version in the readme to 4.0 before next week. If you find compatibility problems, please be sure to post any issues to the support forums so we can figure those out before the final release. You also may want to give your plugin an icon, which we launched last week and will appear in the dashboard along with banners.

It is almost time
For the 4.0 release
And its awesomeness

The fourth and likely final beta for WordPress 4.0 is now available. We’ve made more than 250 changes in the past month, including:

• Further improvements to the editor scrolling experience, especially when it comes to the second column of boxes.
• Better handling of small screens in the media library modals.
• A separate bulk selection mode for the media library grid view.
• Improvements to the installation language selector.
• Visual tweaks to plugin details and customizer panels.

We need your help. We’re still aiming for a release this month, which means the next week will be critical for identifying and squashing bugs. If you’re just joining us, please see the Beta 1 announcement post for what to look out for.

If you think you’ve found a bug, you can post to the Alpha/Beta area in the support forums, where friendly moderators are standing by. Plugin developers, if you haven’t tested WordPress 4.0 yet, now is the time — and be sure to update the “tested up to” version for your plugins so they’re listed as compatible with 4.0.

This software is still in development, so we don’t recommend you run it on a production site. Consider setting up a test site just to play with the new version. To test WordPress 4.0, try the WordPress Beta Tester plugin (you’ll want “bleeding edge nightlies”). Or you can download the beta here (zip).

We are working hard
To finish up 4.0
Will you help us too?

WordPress 3.9.2 is now available as a security release for all previous versions. We strongly encourage you to update your sites immediately.

This release fixes a possible denial of service issue in PHP’s XML processing, reported by Nir Goldshlager of the Salesforce.com Product Security Team. It  was fixed by Michael Adams and Andrew Nacin of the WordPress security team and David Rothstein of the Drupal security team. This is the first time our two projects have coordinated joint security releases.

WordPress 3.9.2 also contains other security changes:

• Fixes a possible but unlikely code execution when processing widgets (WordPress is not affected by default), discovered by Alex Concha of the WordPress security team.
• Prevents information disclosure via XML entity attacks in the external GetID3 library, reported by Ivan Novikov of ONSec.
• Adds protections against brute attacks against CSRF tokens, reported by David Tomaschik of the Google Security Team.
• Contains some additional security hardening, like preventing cross-site scripting that could be triggered only by administrators.

We appreciated responsible disclosure of these issues directly to our security team. For more information, see the release notes or consult the list of changes.

Download WordPress 3.9.2 or venture over to Dashboard → Updates and simply click “Update Now”.

Sites that support automatic background updates will be updated to WordPress 3.9.2 within 12 hours. (If you are still on WordPress 3.8.3 or 3.7.3, you will also be updated to 3.8.4 or 3.7.4. We don’t support older versions, so please update to 3.9.2 for the latest and greatest.)

Already testing WordPress 4.0? The third beta is now available (zip) and it contains these security fixes.

WordPress 4.0 Beta 2 is now available for download and testing. This is software still in development, so we don’t recommend that you run it on a production site. To get the beta, try the WordPress Beta Tester plugin (you’ll want “bleeding edge nightlies”). Or you can download the beta here (zip).

For more of what’s new in version 4.0, check out the Beta 1 blog post. Some of the changes in Beta 2 include:

• Further refinements for the the plugin installation and media library experiences.
• Updated TinyMCE, which now includes better indentation for lists and the restoration of the color picker.
• Cookies are now tied to a session internally, so if you have trouble logging in, #20276 may be the culprit.
• Various bug fixes (there were nearly 170 changes since last week).

If you think you’ve found a bug, you can post to the Alpha/Beta area in the support forums. Or, if you’re comfortable writing a bug report, file one on the WordPress Trac. There, you can also find a list of known bugs and everything we’ve fixed.

WordPress 4.0 Beta 1 is now available!

This software is still in development, so we don’t recommend you run it on a production site. Consider setting up a test site just to play with the new version. To test WordPress 4.0, try the WordPress Beta Tester plugin (you’ll want “bleeding edge nightlies”). Or you can download the beta here (zip).

4.0 is due out next month, but to get there, we need your help testing what we’ve been working on:

• Previews of embedding via URLs in the visual editor and the “Insert from URL” tab in the media modal. Try pasting a URL (such as a WordPress.tv or YouTube video) onto its own line in the visual editor. (#28195, #15490)
• The Media Library now has a “grid” view in addition to the existing list view. Clicking on an item takes you into a modal where you can see a larger preview and edit information about that attachment, and you can navigate between items right from the modal without closing it. (#24716)
• We’re freshening up the plugin install experience. You’ll see some early visual changes as well as more information when searching for plugins and viewing details. (#28785, #27440)
• Selecting a language when you run the installation process. (#28577)
• The editor intelligently resizes and its top and bottom bars pin when needed. Browsers don’t like to agree on where to put things like cursors, so if you find a bug here, please also let us know your browser and operating system. (#28328)
• We’ve made some improvements to how your keyboard and cursor interact with TinyMCE views such as the gallery preview. Much like the editor resizing and scrolling improvements, knowing about your setup is particularly important for bug reports here. (#28595)
• Widgets in the Customizer are now loaded in a separate panel. (#27406)
• We’ve also made some changes to some formatting functions, so if you see quotes curling in the wrong direction, please file a bug report.

If you think you’ve found a bug, you can post to the Alpha/Beta area in the support forums. We’d love to hear from you! If you’re comfortable writing a reproducible bug report, file one on the WordPress Trac. There, you can also find a list of known bugs and everything we’ve fixed so far.

Developers: Never fear, we haven’t forgotten you. There’s plenty for you, too – more on that in upcoming posts. In the meantime, check out the API for panels in the Customizer.

Happy testing!

Plugins, editor
Media, things in between
Please help look for bugs

After three weeks and more than 9 million downloads of WordPress 3.9, we’re pleased to announce that WordPress 3.9.1 is now available.

This maintenance release fixes 34 bugs in 3.9, including numerous fixes for multisite networks, customizing widgets while previewing themes, and the updated visual editor. We’ve also made some improvements to the new audio/video playlists feature and made some adjustments to improve performance. For a full list of changes, consult the list of tickets and the changelog.

If you are one of the millions already running WordPress 3.9, we’ve started rolling out automatic background updates for 3.9.1. For sites that support them, of course.

Download WordPress 3.9.1 or venture over to Dashboard → Updates and simply click “Update Now.”

Thanks to all of these fine individuals for contributing to 3.9.1: Aaron Jorbin, Andrew Nacin, Andrew Ozz, Brian Richards, Chris Blower, Corey McKrill, Daniel Bachhuber, Dominik Schilling, feedmeastraycat, Gregory Cornelius, Helen Hou-Sandi, imath, Janneke Van Dorpe, Jeremy Felt, John Blackbourn, Konstantin Obenland, Lance Willett, m_i_n, Marius Jensen, Mark Jaquith, Milan Dinić, Nick Halsey, pavelevap, Scott Taylor, Sergey Biryukov, and Weston Ruter.

Version 3.9 of WordPress, named “Smith” in honor of jazz organist Jimmy Smith, is available for download or update in your WordPress dashboard. This release features a number of refinements that we hope you’ll love.

A smoother media editing experience

Gallery previews

Galleries display a beautiful grid of images right in the editor, just like they do in your published post.

Do more with audio and video

Images have galleries; now we’ve added simple audio and video playlists, so you can showcase your music and clips.

Live widget and header previews

Add, edit, and rearrange your site’s widgets right in the theme customizer. No “save and surprise” — preview your changes live and only save them when you’re ready.

The improved header image tool also lets you upload, crop, and manage headers while customizing your theme.

Stunning new theme browser

Looking for a new theme should be easy and fun. Lose yourself in the boundless supply of free WordPress.org themes with the beautiful new theme browser.

The second release candidate for WordPress 3.9 is now available for testing.

If you haven’t tested 3.9 yet, you’re running out of time! We made about five dozen changes since the first release candidate, and those changes are all helpfully summarized in our weekly post on the development blog. Probably the biggest fixes are to live widget previews and the new theme browser, along with some extra TinyMCE compatibility and some RTL fixes.

Plugin authors: Could you test your plugins against 3.9, and if they’re compatible, make sure they are marked as tested up to 3.9? It only takes a few minutes and this really helps make launch easier. Be sure to follow along the core development blog; we’ve been posting notes for developers for 3.9. (For example: HTML5, symlinks, MySQL, Plupload.)

To test WordPress 3.9 RC2, try the WordPress Beta Tester plugin (you’ll want “bleeding edge nightlies”). Or you can download the release candidate here (zip). If you’d like to learn more about what’s new in WordPress 3.9, visit the nearly complete About screen in your dashboard ( → About in the toolbar) and also check out the Beta 1 post.

This is for testing,
so not recommended for
production sites—yet.

WordPress 3.8.3 is now available to fix a small but unfortunate bug in the WordPress 3.8.2 security release.

The “Quick Draft” tool on the dashboard screen was broken in the 3.8.2 update. If you tried to use it, your draft would disappear and it wouldn’t save. While we doubt anyone was writing a novella using this tool, any loss of content is unacceptable to us.

We recognize how much trust you place in us to safeguard your content, and we take this responsibility very seriously. We’re sorry we let you down.

We’ve all lost words we’ve written before, like an email thanks to a cat on the keyboard or a term paper to a blue screen of death. Over the last few WordPress releases, we’ve made a number of improvements to features like autosaves and revisions. With revisions, an old edit can always be restored. We’re trying our hardest to save your content somewhere even if your power goes out or your browser crashes. We even monitor your internet connection and prevent you from hitting that “Publish” button at the exact moment the coffee shop Wi-Fi has a hiccup.

It’s possible that the quick draft you lost last week is still in the database, and just hidden from view. As an added complication, these “discarded drafts” normally get deleted after seven days, and it’s already been six days since the release. If we were able to rescue your draft, you’ll see it on the “All Posts” screen after you update to 3.8.3. (We’ll also be pushing 3.8.3 out as a background update, so you may just see a draft appear.)

So, if you tried to jot down a quick idea last week, I hope WordPress has recovered it for you. Maybe it’ll turn into that novella.

Download WordPress 3.8.3 or click “Update Now” on Dashboard → Updates.

This affected version 3.7.2 as well, so we’re pushing a 3.7.3 to these installs, but we’d encourage you to update to the latest and greatest.

Now for some good news:
WordPress 3.9 is near.
Expect it this week
