Back in July bperrybap posted about the work he had done with porting the mighty-1284p core to Arduino 1.5.7. The current version is now 1.5.8 and if you install 1.5.8, it will uninstall your 1.0.5
Is there some other thread about this discussion ?
Any Github site like Jack's where we could download the files for 1.5.x ?
