Original description

What change would like to see?

The avr-gcc in the new 1.0 beta is still at 4.3.2 - while gcc now has had releases 4.5.3 and 4.6.1 for several months.

Why?

The upcoming 1.0 release already introduces lots of changes, this could be a rare opportunity to make a big step forward with avr-gcc as well. Improved optimizations can matter greatly on an embedded platform.

Would this cause any incompatibilities with previous versions? If so, how
can these be mitigated?

I doubt there will be any incompatibilities, gcc is pretty mature by now.

If I understand correctly, an update to the avr toolchain is now best prepared in the (new) https://github.com/arduino/toolchain-avr repository.

Resolved, GCC is now at 4.8.1!
