WordPress is one of the most popular open-source projects in the world, with 70 developers contributing 4,969 commits to the core in 2019. Knowing that, it’s probably not surprising to learn that there’s usually a new WordPress release every single month (if not more like two or three)!
Some of these releases are full new versions or critical security patches, in which we recommend updating all your sites to the latest version fairly quickly. Others are minor fixes or even release candidates that are less critical to update right away or even optional (in the case of beta releases).
How to update WordPress
If your sites are on a managed WordPress host, updates are probably automatically taken care of for you. Flywheel, for example, updates major versions two weeks after release and security updates 24-72 hours after release. Of course, you can always manually update your site yourself or opt out of major version updates if you need more time for testing.

If you’re not working with a managed provider yet, you’ll likely have to manually update your sites to the latest version via the WordPress admin panel. This is very easy to do, but can be time-consuming if you manage lots of client sites.
To update WordPress manually, simply log into wp-admin and look for a notification at the top of the homepage prompting you to update. Click that, and you’re good to go!
Even if your hosting provider takes care of updates for you, it’s still a good idea to be in the know about the latest WordPress version. Then you can make sure your sites are ready for the upgrade and can take advantage of any important new features (like the recent Gutenberg Editor)!
To help you stay up to date with the most current WordPress version, we’ve created this changelog where we’ll publish the details of major version updates, security releases, and maintenance releases.
The latest WordPress version is 5.6 “Simone” which came out on December 8th, 2020. Other recent versions include:
WordPress 5.6 “Simone”
Released on December 8, 2020.
What an exciting day for the release of WordPress 5.6 “Simone”! WordPress 5.6 is the final major release of 2020 and builds upon some of the updates we’ve seen this year, like patterns in the block editor. It’s made history for being led by the first all-female release squad, and was named after the legendary performer Nina Simone. To see what WordPress 5.6 “Simone” means for you and your clients, check out our full overview here!
Highlights of this maintenance release include:
- The option to use the new default theme, Twenty Twenty One. This beautiful theme helps you take full advantage of the Gutenberg block editor. With this new theme, come several new unique patterns you can implement to personalize your WordPress site.
- Updates to the block editor! Along with minor UI updates which will provide a refreshed look to the editing block, you’ll find new default patterns in this release.
- Automatic updates to all new versions of WordPress. If you host your sites on a managed WordPress host like Flywheel, we’ll still handle WordPress updates for you like we always have.
- New REST API authentication for developers for improved security and password management.
WordPress 5.5.1 Maintenance Release
Released on September 1, 2020.
This maintenance release features 34 bug fixes and five enhancements. Nothing too exciting in this short-cycle maintenance release except for improvements in user interface functionality. The WordPress core team is working around the clock to ready WordPress 5.6 for its target release in December!
Highlights of this maintenance release include:
- Fixing an issue so you can now check your site health by using the
- Fixing an issue with XML sitemaps since they were incorrectly paginated in the previous release (woohoo!).
- Removing the ability to change the list of environment types with a new
WordPress 5.5 “Eckstine”
Released on August 12th, 2020.
This new version of WordPress, named after Billy Eckstine, is bringing improvements to three primary areas of your sites: speed, search, and security.
Posts and pages now use lazy loading to feel like they load faster to users. This means images won’t load until they’re about to scroll into view, which should give image-heavy sites a nice boost in performance. (In fact, this is one of our recommended steps when optimizing images for the web!)
By default, WordPress 5.5 will include an XML sitemap from the moment you go live. This will help search engines discover your content sooner, and therefore help more people find your content sooner.
Outdated themes and plugins are one of the most common reasons sites get hacked, but it’s also easy to miss an update (especially if you’re using lots or managing several sites). WordPress 5.5 gives you the new option to set themes and plugins to automatically update when a new version releases, so you can automate the process on a per plugin or per theme basis.
A word of caution: Sometimes an update can cause problems on a site, which is why we usually recommend either making updates on a staging site first or using a service like Flywheel’s Managed Plugin Updates Add-on (in which we’ll review the site and roll back updates if anything breaks).
A few other highlights of WordPress 5.5:
- Create stunning site layouts combining text and media with new block patterns.
- Looking for a new block? Search the directory right from the editor, so you never have to leave your screen to find what you’re looking for!
- Edit images right in the image block. You can now crop, rotate, and zoom without leaving the post or page. Plus you can edit images with an assistive device!
- Copy links in media screens and modals with a button (without trying to highlight the text).
- Move meta boxes with the keyboard.

WordPress 5.4.2 Security and Maintenance Release

WordPress 5.4 “Adderley”
Released on March 31st, 2020.
This major release, named after American jazz trumpeter Nat Adderley, is all about giving you more ways to make your pages come to life without sacrificing speed (in your workflow or your page load time). Let’s start with block updates.
Naturally, enhancements to the Gutenberg Editor were a big focus of this release. Here are some of the new things you’ll see!
- Two new blocks! “Social Icons” and “Buttons,” to increase interactions on your page.
- New color options, such as gradients for Buttons and Covers and added color functionality for Group and Columns blocks.
- A streamlined process for placing and replacing media in blocks.
- The option to have the Media+Text block link to something.
On top of all the block updates, WordPress 5.4 brings cleaner UI and easier navigation. You’ll find things like block breadcrumbs, better tabbing and focus when navigating with the keyboard, and a faster editor load time. (51% faster time to type!)
To round it out, this version also helps with some privacy-related matters (like being able to see progress as you process export and erasure requests), and a number of enhancements specifically for developers.
Here are a few highlights!
- You can add custom fields to menu items natively, thanks to two new actions.
- Blocks are easier to style, and no longer have negative margins and default padding.
- There are two new APIs for block variations and gradients.
- The block editor now supports TikTok in embeds.
WordPress 5.3.2 Maintenance Release
Released on December 18th, 2019.
This maintenance release features 5 fixes and enhancements. Some high-severity tickets were opened shortly after WordPress 5.3.1 was released, so the team pushed this release to solve those issues.
Highlights of the WordPress 5.3.2 updates include:
- Ensuring that
get_feed_build_date()correctly handles a modified post object with an invalid date.
- Fixing a file name collision in
wp_unique_filename()when uploading a file with upper case extension on non case-sensitive file systems.

WordPress 5.3.1 Security and Maintenance Release
Released on December 13th, 2019.
This update features 46 fixes and enhancements, including a number of security improvements. For this reason, updating is highly recommended!
This security release includes fixes for:
- An issue where an unprivileged user could make a post sticky via the REST API.
- An issue where cross-site scripting (XSS) could be stored in well-crafted links.
- Hardening wp_kses_bad_protocol() to ensure it’s aware of the named colon attribute.
- A stored XSS vulnerability using block editor content.
On top of these security updates, WordPress 5.3.1 also introduces several maintenance fixes, such as:
- Avoiding thumbnails overwriting other uploads when filename matches, and excluding PNG images from scaling after upload.
- Ensuring administration email verification uses the user’s locale instead of the site locale.
WordPress 5.3 “Kirk”
Released on November 12th, 2019.
WordPress 5.3, named after jazz multi-instrumentalist Rahsaan Roland Kirk, brings some great improvements to the publishing experience. This version includes the new default theme, Twenty Twenty, which takes full advantage of the block editor to offer new levels of flexibility and design. It also features a variable font for the first time (Inter by Rasmus Andersson), which is easy to read for users and easy to load for browsers.
The block editor was also a major focus of this update, with over 150 new features and usability improvements!
I won’t list them all, but here are some of the highlights:
- Improved image support, specifically for non-optimized, high-resolution photos from a phone or camera.
- Accessibility improvements, including a new Navigation mode that will help users jump from block to block when navigating the dashboard with a keyboard (instead of tabbing through every control).
- Predefined layouts, which makes it easy for content creators to arrange content in advanced designs.
- Additional style options, including the ability to control the text and background color of Heading blocks, support for fixed-width columns in the Columns block, and a new Group block that can be used for creating colorful sections throughout the page.
Beyond the block editor and Twenty Twenty, WordPress 5.3 also introduces some basic improvements that everyone will appreciate. Images will now automatically rotate on upload based on the embedded orientation data – a feature that was first proposed nine years ago! And now when you log into a site as an administrator, you’ll occasionally be asked to verify your email address. This should help reduce the chance of getting locked out in the event that your address changes.
