+ that allow to specify the interrupt vector number as an argument.
+ It allows to use static functions as interrupt handlers, and also
+ functions defined in a C++ namespace.</li>
+ <li>Support has been added for the <code>noblock</code> function
attribute.
+ It can be specified together with the <code>signal</code> attribute to
+ indicate that the interrupt service routine should start with a SEI
+ instruction to globally re-enable interrupts. The difference to the
+ <code>interrupt</code> attribute is that the <code>noblock</code>
+ attribute just acts like a flag and does not impose a specific function
+ name.</li>
+ <li>Support has been added for the <code>__builtin_avr_mask1</code>

masks when
+ code like <code>1 << offset</code> is not fast
enough.</li>
