===================================================================
+    <li>The AVR port's libgcc has been improved and its multilib structure
+      has been enhanced.  As a result, all objects contributing to an
+      application must either be compiled with GCC versions up to 4.6.x or
+      with GCC versions &ge;&nbsp;4.7.</li>

How about "...compiled with older versions of GCC, up to GCC 4.6.x,
or GCC 4.7.0 and later" ?

And I'd omit the &nbsp; just &ge;4.7.0 should work?

+    <li>Support has beed added for instrinsic named address spaces

"Support for...has been added" (also typo: beed -> been)

+    <code>__pgm</code>, <code>__pgm1</code>,&nbsp;&hellip;, <code>__pgm5</code>

How about omitting &nbsp; here?

+    and <code>__pgmx</code>.  These address spaces locate read-only data in
+    flash memory and allow reading from flash memory by means of vanilla
+    C&nbsp;instructions, i.e. without the need of (inline) assembler code.</li>

What's a C instruction?  C builtins?

+    <li>Support for AVR-specific built-in functions has beed added.</li>

Which ones?

+    <li>New command-line options <code>-maccumulate-args</code>,
+      <code>-mbranch-cost=<i>cost</i></code> and <code>-mstrict-X</code>
+      were added to allow better fine-tuning of code optimization.</li>

Should X be put under <i>...</i> here, to?

+    <li>Many optimizations to:
+      <ul>
+	<li>64-bit integer arithmetic</li>
+	<li>Widening multiplication</li>
+	<li>Integer divide-by-constant</li>

"division by a constant"

+ <li>Generic built-in functions + like <code>__builtin_ffs*</code>, 
<code>__builtin_clz*</code>,&nbsp;etc.</li>

I don't think we need &nbsp; here.  Breaing the lines here is something
a web browser should avoid, but it is not verboten, technically.

+	<li>Merging of data in <code>.progmem</code></li>

What is ".progmen"?  Perhaps paraphrase this briefly?

The update is fine assuming you look into my suggestions.

Thanks you,

Gerald
