Linux 3.5 Released
diegocg writes "Linux 3.5 has been released. New features include support for metadata checksums in Ext4, userspace probes for performance profiling with systemtap/perf, a simple sandboxing mechanism that can filter syscalls, a new network queue management algorithm designed to fight bufferbloat, support for checkpointing and restoring TCP connections, support for TCP Early Retransmit (RFC 5827), support for android-style opportunistic suspend, btrfs I/O failure statistics, and SCSI over Firewire and USB. Here's the full changelog."
Linux, the kernel developed and distributed by Linus Torvalds et al, contains software that is included without source code, with obfuscated or obscured source code and code under non-Free Software licenses. Linux-libre removes these parts.
