<ul>
<li>
Due to the new semantics of JavaScript's strict mode, CoffeeScript no
longer guarantees that constructor functions have names in all runtimes.
See <a href="https://github.com/jashkenas/coffee-script/issues/2052">#2052</a>
for discussion.
</li>
<li>
Inside of a nested function inside of an instance method, it's now possible
to call <tt>super</tt> more reliably (walks recursively up).
</li>
<li>
Named loop variables no longer have different scoping heuristics than
other local variables. (Reverts #643)
</li>
<li>
Fix for splats nested within the LHS of destructuring assignment.
</li>
<li>
Corrections to our compile time strict mode forbidding of octal literals.
</li>
</ul>

<ul>
<li>
Due to the new semantics of JavaScript's strict mode, CoffeeScript no
longer guarantees that constructor functions have names in all runtimes.
See <a href="https://github.com/jashkenas/coffee-script/issues/2052">#2052</a>
for discussion.
</li>
<li>
Inside of a nested function inside of an instance method, it's now possible
to call <tt>super</tt> more reliably (walks recursively up).
</li>
<li>
Named loop variables no longer have different scoping heuristics than
other local variables. (Reverts #643)
</li>
<li>
Fix for splats nested within the LHS of destructuring assignment.
</li>
<li>
Corrections to our compile time strict mode forbidding of octal literals.
</li>
</ul>
