<p>
When interpreting a module, it is now checked that the
module does not belong to the Kernel, STDLIB, GS or
Debugger application, as interpreting a module used by
the debugger/interpreter itself will lead to a deadlock
or emulator crash.</p>
<p>
Also <c>int:interpretable(Mod)</c> has been extended to
return <c>{error,{app,App}}</c> if <c>Mod</c> belongs to
one of the above applications.</p>

<section><title>Improvements and New Features</title>
<list>
<item>
<p>It is now possible to encrypt the debug information in
Beam files, to help keep the source code secret. See the
documentation for compile on how to provide the key for
encrypting, and the documentation for beam_lib on how to
provide the key for decryption so that tools such as the
Debugger, Xref, or Cover can be used.</p>
<p>The <c>beam_lib:chunks/2</c> functions now accepts an
additional chunk type '<c>compile_info</c>' to retrieve
the compilation information directly as a term. (Thanks
to Tobias Lindahl.)</p>
