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 id numbers.

• Miniroot installer images include U-Boot 2016.07 with support for EFI payloads.

• vax:

• Removed.

• Improved hardware support, including:

• New bytgpio(4) driver for the Intel Bay Trail GPIO controller.

• New chvgpio(4) driver for the Intel Cherry View GPIO controller.

• New maxrtc(4) driver for the Maxim DS1307 real time clock.

• New nvme(4) driver for the Non-Volatile Memory Express (NVMe) host controller interface.

• New pcfrtc(4) driver for the NXP PCF8523 real time clock.

• New umb(4) driver for the Mobile Broadband Interface Model (MBIM).

• New ure(4) driver for RealTek RTL8152 based 10/100 USB Ethernet devices.

• New utvfu(4) driver for audio/video capture devices based on the Fushicai USBTV007.

• The iwm(4) driver now supports Intel Wireless 3165 and 8260 devices, and works more reliably in RAMDISK kernels.

• Support for I2C HID devices with GPIO signalled interrupts has been added to dwiic(4).

• Support for larger bus widths, high speed modes, and DMA transfers has been added to sdmmc(4), rtsx(4), sdhc(4), and imxesdhc(4).

• 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.

• Problems with dead keyboards after resume have been fixed in the pckbd(4) driver.

• The rtsx(4) driver now supports RTS522A devices.

• Initial support for MSI-X has been added.

• Support MSI-X in the virtio(4) driver.

• 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.

• The uslcom(4) driver now supports the serial console of Aruba 7xxx wireless controllers.

• The re(4) driver now works around broken LED configurations in APU1 EEPROMs.

• The ehci(4) driver now works around problems with ATI USB controllers (e.g. SB700).

• The xen(4) driver now supports domU configuration under Qubes OS.
