io.js 2.0.2 发布，此版本值得关注的改进如下： win,node-gyp: the delay-load hook for windows addons
has now been correctly enabled by default, it had wrongly defaulted to
off in the release version of 2.0.0 (Bert Belder) #1433 os: tmpdir()'s trailing slash stripping
has been refined to fix an issue when the temp directory is at '/'. Also
considers which slash is used by the operating system. (cjihrig) #1673 tls: default ciphers have been updated to use gcm and aes128 (Mike MacCana) #1660 build: v8 snapshots have been re-enabled by default as
suggested by the v8 team, since prior security issues have been
resolved. This should give some perf improvements to both startup and vm
context creation. (Trevor Norris) #1663 src: fixed preload modules not working when other flags were used before --require (Yosuke Furukawa) #1694 dgram: fixed send()'s callback not being asynchronous (Yosuke Furukawa) #1313 readline: emitKeys now keeps buffering data until it
has enough to parse. This fixes an issue with parsing split escapes.
(Alex Kocharin) #1601 cluster: works now properly emit 'disconnect' to cluser.worker (Oleg Elifantiev) #1386 events: uncaught errors now provide some context (Evan Lucas) #1654
