Node v5.1.0 稳定版发布，更新如下：
重要更新
buffer: The noAssert option for many buffer functions will now silently drop invalid write values rather than crashing (P.S.V.R) #3767.
This makes the behavior match what the docs suggest.
child_process: child.send() now properly returns a boolean like the docs suggest (Rich Trott) #3577.
doc: All of the API docs have been re-ordered so as to read in alphabetical order (Tristian Flanagan) #3662.
http_parser: update http-parser to 2.6.0 from 2.5.0 (James M Snell) #3569.
Now supports the following HTTP methods: LINK, UNLINK, BIND, REBIND, UNBIND.
Also added ACL and IPv6 Zone ID support.
npm: upgrade npm to 3.3.12 from v3.3.6 (Rebecca Turner) #3685.
See the release notes for v3.3.7, v3.3.8, v3.3.9, v3.3.10, v3.3.11, and v3.3.12 for more details.
repl: The REPL no longer crashes if the persistent history file cannot be opened (Evan Lucas) #3630.
tls: The default sessionIdContext now uses SHA1 in FIPS mode rather than MD5 (Stefan Budeanu) #3755.
v8: Added some more useful post-mortem data (Fedor Indutny) #3779.
