Yep.
For XMega GitHub - Xmegaduino/Xmegaduino: Xmegaduino fork of Arduino
I atach the zipped hardware directory with extended XMega entry with additional 32A4(U), Xmega256A3U. The XMega 32E5 is not ready yet. The boatloader is inoperativ, but I have a PDI programmer and with AtmelStudio no need for that.
Copy the xmega directory in the IDE 1.5.7 hardware directory.
