I noticed that devtoolset 4.1 was available at http://buildlogs.centos.org/centos/6/sclo/x86_64/rh/devtoolset-4/.

Howeever it's not available on the official mirrors at http://mirror.centos.org/centos-6/6/sclo/x86_64/rh/devtoolset-4/.

Any idea when devtoolset-4 will be available for general release.  I'd be glad to help building or testing devtoolset 4.1.

Thanks.
