 Updated for early October 2025 based on
 [https://wordpress.org/about/stats/ WordPress stats].

 7.2 + 7.3 that are slated to be the next PHP versions no longer supported
 by WordPress, continued dropping and reached 4.25%. This is a reduction of
 0.14% since last month. If the current pace continues, we will be below 4%
 by the time WP 6.9 is released in early December, and it will likely drop
 below the percentage of sites already abandoned with the dropped support
 for PHP 5.2 - 7.0 in WP 6.6.

 For historical reasons, here are the stats for no longer supported
 versions (support removed in WP 6.6). This is not changing much and many
 are likely "abandoned" sites that are on old versions of WP. As we stand
 now, 3.98% of sites are on unsupported PHP versions, something that
 dropped 0.12% in the past month. Since Jan, we dropped a full percentage
 point, something pretty significant.
