Qubes OS 2 RC1 發布，面向安全的、基于Fedora的桌面Linux發行
Qubes OS是面向安全的、基于Fedora的桌面Linux發行，其主要理念是基于隔離的安全，而這靠輕量級的Xen虛擬機來實現隔離域。它旨在結合兩個貌似矛盾的目標：如何使不同域之間的隔離盡可能強，這主要靠能夠使可信代碼盡量小的更靈巧的結構，以及如何使這種隔離盡可能無縫和容易。 
Today
we're releasing Qubes OS R2 RC1 (release candidate), which is expected
to be the last milestone before the final Qubes OS R2 release. As
mentioned previously today's release is bringing mainly UI improvements
and polishing and lots of bug fixes, as well as some last new features.
Both Dom0 and VMs have been upgraded to Fedora 20. Support for full
templates download via two new repo definitions - templates-itl and
templates-community. With a bit of imagination we could call it Qubes
'AppStore' for VMs. Currently we have only published one template there –
the new default FC20-based template, but we plan to upload more
templates in the coming weeks.
