The latest stable version of the Linux kernel is 2.6.10

Linux has as well been ported to a number of architectures without a PMMU, although functionality is then obviously somewhat limited. See the uClinux project for more info.

It has all the features you would expect in a modern fully-fledged Unix, including true multitasking, virtual memory, shared libraries, demand loading, shared copy-on-write executables, proper memory management, and TCP/IP networking.

Linux is easily portable to most general-purpose 32- or 64-bit architectures as long as they have a paged memory management unit (PMMU) and a port of the GNU C compiler (gcc).

Linux is a clone of the operating system Unix, written from scratch by Linus Torvalds with assistance from a loosely-knit team of hackers across the Net. It aims towards POSIX and Single UNIX Specification compliance.

Linux was first developed for 32-bit x86-based PCs (386 or higher). These days it as well runs on (at least) the Compaq Alpha AXP, Sun SPARC and UltraSPARC, Motorola 68000, PowerPC, PowerPC64, ARM, Hitachi SuperH, IBM S/390, MIPS, HP PA-RISC, Intel IA-64, DEC VAX, AMD x86-64 and CRIS architectures.

What's new in this release

• Based on patch from Pavel Roskin :
• Start migrating get_wireless_stats to struct iw_handler_def
• Allow any size GET request if user specifies length > max
• Remove spy #ifdef, they are always on -> cleaner code
• Change the way we get to spy_data technique for added safety and hostap
• Add support for relative TxPower (yick !)
• Wireless Event capability in struct iw_range
• Document (struct iw_quality *)->updated, add recent flags (INVALID)
• Add flags to frequency -> auto/fixed
