OpenIndiana is a free and open-source Unix operating system derived from OpenSolaris and based on illumos. Developers forked OpenSolaris after Oracle Corporation discontinued it, in order to continue development and distribution of the source code.
New Feature: Hybrid Torrents
Hybrid torrents support the BitTorrent V1 and V2 protocol. Its support is not well spread out yet so we recommend that you still use v1 (aka the "torrent" column).
