WPML 4.8.5 includes behind-the-scenes improvements for better performance, stability, and security.

Smoother Site Migrations

Moving your site to a new domain? We’ve fixed two issues:

  • The setup wizard no longer gets stuck. If you moved your site while going through the WPML setup wizard, you might have found yourself stuck at the AI translation step. The wizard now recognizes domain changes correctly, allowing you to complete the setup without disruption.
  • Translation credits sync immediately. Before, when you assigned translation credits to your site from WPML.org after a migration, you might have experienced delays or missing credits. Now, credits are available the moment you assign them.

Performance Enhancements

This release introduces several optimizations that improve how WPML runs in the background:

  • Faster translation workflow – The Advanced Translation Editor now loads more quickly. It automatically uses the fastest connection method available while respecting your site’s security policies.
  • Improved handling of large translation batches – Sending content for translation in many languages at once (13+ languages) now works consistently, without missing or failed jobs.
  • Lower server load – We’ve fixed queries that could multiply with each open page in a different language, which caused higher CPU and memory usage on high-traffic sites.
  • Internal communication improvements – We’ve optimized how your site communicates with WPML.org, reducing unnecessary background requests. This makes WPML more efficient without changing how you use it.

Updated JavaScript Library for Security Compliance

WPML now uses the latest Axios JavaScript library (1.13.1) following a reported vulnerability in that library. The issue was not exploitable through our plugin, but we applied the fix to stay compliant with best security practices.

Security remains our top priority. If you ever discover a potential security issue in any WPML plugin, please report it through our security and vulnerability page.

We are releasing WPML 4.8.5 gradually. Once it is available on your website, we recommend updating to benefit from these latest improvements.

  1. Thanks for this “quiet” but really important release – smoother migrations, faster ATE and the extra care on performance and security are exactly what keep WPML reliable on busy client sites.
