                　　OpenBSD 6.0 发布了，OpenBSD是一个从NetBSD衍生出来的类Unix操作系统。专案领导人Theo de Raadt在1995年]发起了OpenBSD专案，希望创造一个注重安全的操作系统，此外OpenBSD也以高品质的文件、坚持开放程式码以及严格的软件授权著名。OpenBSD的吉祥物是河豚。
　　该版本改进如下：

• 　　默认启用内存保护策略W^X（也就是内存页要么可写要么可执行，无法两者兼具）；
  
• 　　ARMv7平台支持EFI + bootloader；
  
• 　　改进硬件支持；
  
• 　　改进 IEEE 802.11 无线网络协议栈；
  
• 　　软件更新如OpenSMTPD 6.0.0、OpenSSH 7.3、OpenNTPD 6.0和 LibreSSL 2.4.2；
  
• 　　移除VAX支持、Linux模拟和kern.usermount，等等
  

　　New/extended platforms:

• 　　armv7:
  
  
  
  • 　　EFI bootloader added, kernels are now loaded from FFS instead of FAT or EXT filesystems, without U-Boot headers.
    
  • 　　A single kernel and ramdisk are now used for all SoCs.
    
  • 
    　　Hardware is dynamically enumerated via Flattened Device Tree (FDT) instead of via static tables based on board>
    
  • 　　Miniroot installer images include U-Boot 2016.07 with support for EFI payloads.
    
  
  
• 　　vax:

  • 
    　　The iwm(4) driver now supports Intel Wireless 3165 and 8260 devices, and works more>
    
  • 　　Support for I2C HID devices with GPIO signalled interrupts has been added to dwiic(4).
    
  • 
    　　Support for larger bus>
    
  • 　　Support for EHCI and OHCI compliant USB controllers on Octeon II SoCs.
    
  • 　　Many USB device drivers have been enabled on OpenBSD/octeon.
    
  • 　　Improved support for hardware-reduced ACPI implementations.
    
  • 　　Improved support for ACPI 5.0 implementations.
    
  • 　　AES-NI crypto is now done without holding the kernel lock.
    
  • 　　Improved AGP support on PowerPC G5 machines.
    
  • 　　Added support for the SD card slot in Intel Bay Trail SoCs.
    
  • 　　The ichiic(4) driver now ignores the SMBALERT# interrupt to prevent an interrupt storm with buggy BIOS implementations.
    
  • 　　Device attachment problems with the axen(4) driver have been fixed.
    
  • 　　The ral(4) driver is more stable under load with RT2860 devices.

  • 　　Added a workaround for hardware DMA overruns to the dc(4) driver.
    
  • 　　The acpitz(4) driver now spins the fan down after cooling if ACPI uses hysteresis for active cooling.
    
  • 　　The xhci(4) driver now performs handoff from an xHCI-capable BIOS correctly.
    
  • 　　Support for multi-touch input has been added to the wsmouse(4) driver.
