  • On AVR, support has been added for the devices ATtiny4/5/9/10/20/40. + This requires Binutils 2.25 or newer.

  • The AVR port uses a new scheme to describe supported devices: + For each supported device the compiler provides a device-specific + spec file. + If the compiler is used together with AVR-LibC, this requires at + least GCC 5.2 and a version of AVR-LibC which implements + #44574.
