+========================================================
+Deprecation: #94791 - GeneralUtility::minifyJavaScript()
+========================================================
+
+See :issue:`94791`
+
+Description
+===========
+
+The static method :php:`TYPO3\CMS\Core\Utility\GeneralUtility::minifyJavaScript()`
+has been marked as deprecated.
+
+Back in TYPO3 4.x times, the "jsmin" library was used to minify
+JavaScript, however as this became more flexible, a hook was
+introduced, and then "jsmin" was removed again. Since then,
+the hook to minify inline JavaScript is used in PageRenderer,
+and should rather be moved into the :php:`ResourceCompressor` functionality,
+where it resides now.
+
+The hook itself works exactly as before.
+
+
+Impact
+======
+
+Calling the method will trigger a PHP :php:`E_USER_DEPRECATED` error. Extension
+scanner will detect calls as strong match.
+
+
+Affected Installations
+======================
+
+TYPO3 installations with custom extensions calling this method,
+which is highly unlikely.
+
+Custom extensions using this hook will still work as before without any changes.
+
+
+Migration
+=========
+
+As this method was used to only trigger a hook, it is recommended
+to use the :php:`PageRenderer` and :php:`ResourceCompressor` API instead, removing
+any direct calls to this method.
+
+If still needed, extension authors can also copy the hook call
+execution to use the hook logic, which is not recommended though.
