+ <p>In embedded mode, on_load handlers that called
+ <c>code:priv_dir/1</c> or other functions in <c>code</c>
+ would hang the system. Since the <c>crypto</c>
+ application now contains an on_loader handler that calls
+ <c>code:priv_dir/1</c>, including the <c>crypto</c>
+ application in the boot file would prevent the system
+ from starting.</p>
+ <p>Also extended the <c>-init_debug</c> option to print
+ information about on_load handlers being run to
+ facilitate debugging.</p>
