+    Due to security concerns with ``SharedArrayBuffer`` due to various exploits,
+    the use of multiple threads for the Web platform has multiple drawbacks,
+    including requiring specific server-side headers and complete cross-origin isolation
+    (meaning no ads, nor third-party integrations on the website hosting your game).
+
+    Since Godot 4.3, Godot supports exporting your game on a single thread, which
+    solves this issue. While it has some drawbacks on its own (it cannot use threads, and is
+    not as performant as the multi-threaded export), it doesn't require as much overhead to install.
+    It is also more compatible overall with stores like `itch.io <https://itch.io/>` or Web publishers like
+    `Poki <https://poki.com/>`__ or `CrazyGames <https://crazygames.com/>`__. The single-threaded export
+    works very well on macOS and iOS too, where it always had compatibility issues with multiple threads
+    exports.
+
+    For these reasons, it is the preferred and now default way to export your games on the Web.
