FreeBSD 10.3-RC2发布了。 更新日志： Noteworthy Changes Since 10.3-RC1 ： Under certain circumstances, `zfs send -i`, i. e. incremental ZFS send, could lead to data corruption, which has been addressed by importing an upstream fix. Boot loaders and kernel have been taught to handle ELF sections of type SHT_AMD64_UNWIND just the same as SHT_PROGBITS when loading modules. While not directly relevant for 10.3-RELEASE, clang as of version 3.8 started to produce sections of the former type in amd64 modules. Thus, this changes will simplify upgrades from 10.3-RELEASE to 11.0-RELEASE later on. As part of closing or syncing a hash(3)-based database file, fsync(2) now is called on the latter. This ensures that changes are on disk when shutting down a machine, which previously was not always the case with soft updates in place. Additionally, this change allowed removal of O_SYNC in the dbopen(3) calls of cap_mkdb(1), pwd_mkdb(8) as well as services_mkdb(8), speeding these up on large database files. Open Issues： A fix for CVE-2016-3115, and the re-addition of AES-CBC ciphers to the default server proposal list. These have been removed as part of the previous upgrade to OpenSSH version 7.1p2, breaking e. g. lightweight clients making still use of AES-CBC ciphers in order to be able to employ hardware crypto acceleration. 文章来源：http://distrowatch.com/?newsid=09325 FreeBSD 10.3-RC2 发布下载地址
