WordPress 7.1 Has Arrived: Easier Updates, Better Editing and a Sensible Approach to Security

WordPress 7.1, known as “Mary Lou”, was released on 19 August 2026. It is the latest major update to the software that powers millions of websites, including many small business websites across the UK.

This release is less about changing everything overnight and more about making everyday website work easier, particularly when adding content, working with images and keeping pages looking good on mobiles. It also includes important behind-the-scenes improvements, which is one reason it is worth planning for properly.

What does WordPress 7.1 mean for small businesses?

For most business owners, the useful changes are the practical ones. WordPress 7.1 makes it easier for website designers and content editors to create pages that work well on different screen sizes, manage images and collaborate on content.

That matters because your website is likely to be viewed on a phone just as often, if not more often, than on a desktop computer. Small adjustments to spacing, buttons, headings and layouts can make a real difference to how easy it is for potential customers to use your site.

The new version brings more responsive design controls into WordPress itself. In simple terms, this gives developers more flexibility to make sure a page looks right on desktop, tablet and mobile without needing to add as much custom code.

That does not mean every existing website will suddenly look different after the update. It means there are better tools available when we make future improvements, build new pages or refresh parts of a site.

A more straightforward way to work with images

Images are often one of the most time-consuming parts of updating a website. You may need to crop a photo, rotate it, resize it or find an image you uploaded previously.

WordPress 7.1 includes a redesigned media editor intended to make these tasks more straightforward. It brings common image-editing tasks together in one clearer place, helping content editors prepare images before they are added to a page or post.

There are also improvements to the way WordPress processes images during upload. On supported browsers, some of that work can happen before the image reaches the web server. This can reduce the work your website’s server has to do and should help make image uploads more efficient.

As with any change to image handling, it is sensible to test websites that use specialist image tools, galleries, booking systems, shops or custom-built functionality. A standard brochure website is unlikely to need much attention, but every website deserves a proper check.

Better collaboration when more than one person works on a website

If several people are involved in approving or updating content, WordPress 7.1 also improves its Notes feature.

This allows users to leave feedback against specific parts of a page and mention another person who needs to review it. It is not a replacement for a good conversation, but it can be useful when a business owner, marketing team and web designer are all working through changes together.

For smaller businesses, this could mean fewer crossed wires when reviewing a new page, campaign landing page or updated service information.

Is WordPress 7.1 a security update?

This is an important distinction. WordPress 7.1 is a major feature release, not an emergency security update.

Major releases include new functionality and improvements, so they should be handled with a little more care than a routine security patch. Updating immediately without checking compatibility can sometimes cause issues with older plugins, themes or custom website features.

That does not mean the update should be ignored. Keeping WordPress, plugins and themes properly maintained is an essential part of website security. Older software can eventually become more vulnerable, especially when security fixes are no longer provided for previous versions.

The sensible approach is to take a backup, test the update where appropriate, check the important parts of the site and then apply it to the live website once everything is behaving as expected.

At O’Brien Media, that is how we approach major WordPress updates. We do not treat every new version as something to rush onto every live website on release day. We assess it, test for compatibility and make sure the update is appropriate for the individual site.

What should you do now?

If you manage your own WordPress website, avoid clicking update simply because a new version is available. First, make sure you have a recent backup and check that your essential plugins and theme are actively maintained.

If your website includes an online shop, booking system, membership area, bespoke functions or integrations with other systems, testing is especially worthwhile.

If you have an O’Brien Media website support agreement, we will take care of the assessment and update process as part of looking after your website, provided there is support time available on your account. You can check your available support time through Client Connect.

WordPress 7.1 is a positive update. Its improvements should make websites easier to edit, help pages work better across different devices and give designers more useful tools for future changes. The key is to introduce it carefully, so your website gains the benefits without creating unnecessary disruption.
