 # io.js 更新记录
 
+## [2015-03-31, Version 1.6.3, @rvagg](https://github.com/iojs/io.js/blob/v1.x/CHANGELOG.md#2015-03-31-version-163-rvagg)
+
+### Notable changes
+
+* **fs**: corruption can be caused by `fs.writeFileSync()` and append-mode `fs.writeFile()` and `fs.writeFileSync()` under certain circumstances, reported in [#1058](https://github.com/iojs/io.js/issues/1058), fixed in [#1063](https://github.com/iojs/io.js/pull/1063) (Olov Lassus).
+* **iojs**: an "internal modules" API has been introduced to allow core code to share JavaScript modules internally only without having to expose them as a public API, this feature is for core-only [#848](https://github.com/iojs/io.js/pull/848) (Vladimir Kurchatkin).
+* **timers**: two minor problems with timers have been fixed:
+  - `Timer#close()` is now properly idempotent [#1288](https://github.com/iojs/io.js/issues/1288) (Petka Antonov).
+  - `setTimeout()` will only run the callback once now after an `unref()` during the callback [#1231](https://github.com/iojs/io.js/pull/1231) (Roman Reiss).
+  - NOTE: there are still other unresolved concerns with the timers code, such as [#1152](https://github.com/iojs/io.js/pull/1152).
+* **Windows**: a "delay-load hook" has been added for compiled add-ons on Windows that should alleviate some of the problems that Windows users may be experiencing with add-ons in io.js [#1251](https://github.com/iojs/io.js/pull/1251) (Bert Belder).
+* **V8**: minor bug-fix upgrade for V8 to 4.1.0.27.
+* **npm**: upgrade npm to 2.7.4. See [npm CHANGELOG.md](https://github.com/npm/npm/blob/master/CHANGELOG.md#v274-2015-03-20) for details. Summary:
+  * [`1549106`](https://github.com/npm/npm/commit/1549106f518000633915686f5f1ccc6afcf77f8f) [#7641](https://github.com/npm/npm/issues/7641) Due to 448efd0, running `npm shrinkwrap --dev` caused production dependencies to no longer be included in `npm-shrinkwrap.json`. Whoopsie! ([@othiym23](https://github.com/othiym23))
+  * [`fb0ac26`](https://github.com/npm/npm/commit/fb0ac26eecdd76f6eaa4a96a865b7c6f52ce5aa5) [#7579](https://github.com/npm/npm/issues/7579) Only block removing files and links when we're sure npm isn't responsible for them. This change is hard to summarize, because if things are working correctly you should never see it, but if you want more context, just [go read the commit message](https://github.com/npm/npm/commit/fb0ac26eecdd76f6eaa4a96a865b7c6f52ce5aa5), which lays it all out. ([@othiym23](https://github.com/othiym23))
+  * [`051c473`](https://github.com/npm/npm/commit/051c4738486a826300f205b71590781ce7744f01) [#7552](https://github.com/npm/npm/issues/7552) `bundledDependencies` are now properly included in the installation context. This is another fantastically hard-to-summarize bug, and once again, I encourage you to [read the commit message](https://github.com/npm/npm/commit/051c4738486a826300f205b71590781ce7744f01) if you're curious about the details. The snappy takeaway is that this unbreaks many use cases for `ember-cli`. ([@othiym23](https://github.com/othiym23))
+  * [`fe1bc38`](https://github.com/npm/npm/commit/fe1bc387a14475e373557de669e03d9d006d3173)[#7672](https://github.com/npm/npm/issues/7672) `npm-registry-client@3.1.2`: Fix client-side certificate handling by correcting property name. ([@atamon](https://github.com/atamon))
+  * [`89ce829`](https://github.com/npm/npm/commit/89ce829a00b526d0518f5cd855c323bffe182af0)[#7630](https://github.com/npm/npm/issues/7630) `hosted-git-info@1.5.3`: Part 3 of ensuring that GitHub shorthand is handled consistently. ([@othiym23](https://github.com/othiym23))
+  * [`63313eb`](https://github.com/npm/npm/commit/63313eb0c37891c355546fd1093010c8a0c3cd81)[#7630](https://github.com/npm/npm/issues/7630) `realize-package-specifier@2.2.0`: Part 2 of ensuring that GitHub shorthand is handled consistently. ([@othiym23](https://github.com/othiym23))
+  * [`3ed41bf`](https://github.com/npm/npm/commit/3ed41bf64a1bb752bb3155c74dd6ffbbd28c89c9)[#7630](https://github.com/npm/npm/issues/7630) `npm-package-arg@3.1.1`: Part 1 of ensuring that GitHub shorthand is handled consistently. ([@othiym23](https://github.com/othiym23))
+
+### Known issues
+
+* Some problems exist with timers and `unref()` still to be resolved. See [#1152](https://github.com/iojs/io.js/pull/1152).
+* Possible small memory leak(s) may still exist but have yet to be properly identified, details at [#1075](https://github.com/iojs/io.js/issues/1075).
+* Surrogate pair in REPL can freeze terminal [#690](https://github.com/iojs/io.js/issues/690)
+* Not possible to build io.js as a static library [#686](https://github.com/iojs/io.js/issues/686)
+* `process.send()` is not synchronous as the docs suggest, a regression introduced in 1.0.2, see [#760](https://github.com/iojs/io.js/issues/760) and fix in [#774](https://github.com/iojs/io.js/issues/774)
+* Calling `dns.setServers()` while a DNS query is in progress can cause the process to crash on a failed assertion [#894](https://github.com/iojs/io.js/issues/894)
+
+## [2015-03-23, Version 1.6.2, @rvagg](https://github.com/iojs/io.js/blob/v1.x/CHANGELOG.md#2015-03-23-version-162-rvagg)
+
+### Notable changes
+
+* **Windows**: The ongoing work in improving the state of Windows support has resulted in full test suite passes once again. As noted in the release notes for v1.4.2, CI system and configuration problems prevented it from properly reporting problems with the Windows tests, the problems with the CI and the codebase appear to have been fully resolved.
+* **FreeBSD**: A [kernel bug](https://lists.freebsd.org/pipermail/freebsd-current/2015-March/055043.html) impacting io.js/Node.js was [discovered](https://github.com/joyent/node/issues/9326) and a patch has been introduced to prevent it causing problems for io.js (Fedor Indutny) [#1218](https://github.com/iojs/io.js/pull/1218).
+* **module**: you can now `require('.')` instead of having to `require('./')`, this is considered a bugfix (Michaël Zasso) [#1185](https://github.com/iojs/io.js/pull/1185).
+* **v8**: updated to 4.1.0.25 including patches for `--max_old_space_size` values above `4096` and Solaris support, both of which are already included in io.js.
+
+### Known issues
+
+* Possible small memory leak(s) may still exist but have yet to be properly identified, details at [#1075](https://github.com/iojs/io.js/issues/1075).
+* Surrogate pair in REPL can freeze terminal [#690](https://github.com/iojs/io.js/issues/690)
+* Not possible to build io.js as a static library [#686](https://github.com/iojs/io.js/issues/686)
