• Null (loopback) filesystem
• Umap uid-mapping filesystem
• Security: Immutable, append-only, other flags
• VM: mmap(\|) more robust
• VM: many improvements
• sysctl(\|) kernel control interface
• Security levels
• Better CPU statistics and profiling
• Link-layer routes; ARP now in routing table
• ICMP: MTU discovery
• TCP: large window, timestamp options
• Improved autoconfiguration framework, config program (including multiple-device wildcards)
• SMC 8416 EtherEZ Ethernet support
• Symlinks have no owners; chown follows symlinks
• dev_t now using 32-bits, new encoding
• New standalone code: serial console support, BIOS-based boot

Software

• Shared Libraries
• SCO Binary Compatibility
• Dramatically improved configuration and installation software

• New/improved system monitoring utilities (`systat' is new; vmstat, iostat, etc. have been updated)
• Incremental (fast) updates to passwd file
• Faster sorting functions: qsort, radixsort, mergesort
• Latest networking utilities:
