Changelog

String Translation 5.0.0 focuses on a faster, more reliable Strings screen and translation queue, fixes taxonomy and slug translation, and makes string handling consistent on sites whose default language is a regional English variant.

Faster, more reliable string screen and queue

  • The String Translation screen now loads faster because it uses an indexed lookup instead of scanning every string.
  • Adding a new language no longer times out and only loads the translations you actually need for that language.
  • Sites with a large number of auto-registered frontend strings no longer run into timeout errors while the queue is processed.
  • String registration and the pending-strings queue are now more fault-tolerant, so a single bad file or database write no longer blocks every later string.
  • The cache behind your site’s translated language files now stays within a safe memory budget instead of growing without limit.

Taxonomy and slug translation fixes

  • Translating a taxonomy’s slug now actually takes effect on the front end.
  • Taxonomy labels are now registered and shown under the correct source language, fixing labels that incorrectly appeared as translated.

Consistent behavior on English-variant sites

  • String Translation now behaves consistently when your site’s default language is a regional English variant such as en-US or en-GB.

Also in this release

  • Searching strings by language name or text now returns results again.
  • Uploading a .po file and adding the selected strings works again on the Strings tab.
  • Changing a string’s language now works correctly for non-admin Translation Managers, without a JavaScript error.
  • String Translation now correctly scans themes and plugins when WPML is installed through a symbolic link.
  • WPML now respects a custom REST API prefix instead of assuming the default one.

Security

  • This release includes security hardening.
