Is Regenerate Thumbnails still maintained?
Not actively. The last release of Regenerate Thumbnails was 13 months ago. That is not long enough to call it abandoned, and it is long enough to be worth knowing about before your next WordPress or PHP upgrade.
The evidence
Every figure below is read from the WordPress.org plugin directory. Nothing here is our assessment of the code.
| Last release | 20 August 2025 (13 months ago) |
|---|---|
| Current version | 3.1.6 |
| Tested up to | WordPress 6.8.8 (current is 7.1, 3 releases ahead) |
| Requires PHP | 5.2.4 |
| Active installs | At least 1 million sites (the directory reports a rounded floor, not an exact count) |
| Support threads resolved | No threads in the last two months |
| Directory status | Listed |
| Read from the directory | 16 September 2026 |
What these signals mean
A year without a release is a signal rather than a verdict. Plenty of narrow plugins genuinely need no changes for a year, and WordPress is unusually careful about backwards compatibility, so nothing has necessarily gone wrong.
What it changes is who fixes it if something does. A maintained plugin is one where a breaking change in PHP or WordPress core produces a release; an unmaintained one is where it produces a support thread nobody answers. Treat the gap as a reason to know what you would move to, not as a reason to move today.
What to do about it
Nothing urgent. Note it, and know what you would replace it with, so that the decision is already made if a PHP or WordPress upgrade breaks something.
The moment to act is before an upgrade rather than after one. If you are planning a PHP version bump or a major WordPress release, test this plugin on a staging copy first, because an unmaintained plugin is the one nobody is going to fix for you.
Is a site you look after running Regenerate Thumbnails?
Our free WordPress plugin checker reads any public site and lists the plugins it loads, with the same maintenance signals as the table above for each one. No login and no signup, so it works on a client’s site before you have access to it.
Maintained alternatives
From the same category in the WordPress.org directory, filtered to plugins that have shipped a release in the last year and are installed on at least 10,000 sites. Chosen by those rules rather than by us, and worth checking against the same signals before you commit to one.

Questions
When was Regenerate Thumbnails last updated?
The WordPress.org directory records its most recent release as 20 August 2025, which is 13 months ago. That date is read from the directory each time this page is built, and the page states when it was read.
Should I remove Regenerate Thumbnails from my site?
Not on the strength of the date alone. 13 months without a release is a reason to know what you would replace it with, not a reason to replace it today. The moment that matters is a PHP or WordPress upgrade, because that is when an unmaintained plugin breaks and nobody is there to fix it.
Is Regenerate Thumbnails a security risk?
We do not know, and nothing on this page is a security finding. Vulnerability data for WordPress plugins sits behind paid commercial APIs, and guessing at it from a version number either alarms people about plugins that are fine or implies that everything unflagged has been checked and is safe. Both are worse than saying nothing. What this page reports is maintenance: when the plugin last shipped, which WordPress version its author last tested against, how much of its support forum gets answered, and whether the directory still lists it. Those are facts the directory publishes, and they are what predicts whether a plugin will still work after the next core release.
