+ *
+ * Before version 2.36 this function would ignore the `HOME` environment
+ * variable, taking the value from the `passwd` database instead. This was
+ * changed to increase the compatibility of GLib with other programs (and
+ * the XDG basedir specification) and to increase testability of programs
+ * based on GLib (by making it easier to run them from test frameworks).
+ *
+ * If your program has a strong requirement for either the new or the
