­　　NetBSD 8.0 發(fā)布了，NetBSD 是一個(gè)免費(fèi)的、安全的及高度可移植的開(kāi)源 UNIX 操作系統(tǒng)，它適合于很多種平臺(tái)，從 64 位的 AlphaServers 及桌面系統(tǒng)到手持及嵌入式系統(tǒng)。它在設(shè)計(jì)上非常整潔，并擁有先進(jìn)的特性，這使得它在業(yè)界和學(xué)術(shù)界都有口皆碑。用戶可通過(guò)完整的源代碼來(lái)獲得支持。很多應(yīng)用程序都可容易地從 NetBSD Packages Collection 獲得。

­　　此次更新帶來(lái)了穩(wěn)定性改進(jìn)、數(shù)百個(gè) bug 修復(fù)和許多新功能，主要內(nèi)容包括：

­　　USB stack rework, USB3 support added.

­　　In-kernel audio mixer (audio_system(9)).

­　　Reproducible builds (MKREPRO, see mk.conf(5)).

­　　Full userland debug information (MKDEBUG, see mk.conf(5)) available. While most install media do not come with them (for size reasons), the debug and xdebug sets can be downloaded and extracted as needed later. They provide full symbol information for all base system and X binaries and libraries and allow better error reporting and (userland) crash analysis.

­　　PaX MPROTECT (W^X) memory protection enforced by default on some architectures with fine-grained memory protection and suitable ELF formats: i386, amd64, evbarm, landisk, pmax.

­　　PaX ASLR (Address Space Layout Randomization) enabled by default on: i386, amd64, evbarm, landisk, pmax, sparc64.

­　　Position independent executables by default for userland on: i386, amd64, arm, m68k, mips, sh3, sparc64.

­　　A new socket layer can(4) has been added for communication of devices on a CAN bus.

­　　A special pseudo interface ipsecif(4) for route-based VPNs has been added.

­　　Parts of the network stack have been made MP-safe. The kernel option NET_MPSAFE is required to enable this.

­　　Hardening of the network stack in general.

­　　Various WAPBL (the NetBSD file system "log" option) stability and performance improvements.

­　　詳情見(jiàn)發(fā)布公告。
