+# io.js 1.6 release
+This week we had a two io.js releases [v1.6.1](https://iojs.org/dist/v1.6.1/) and  [v1.6.0](https://iojs.org/dist/v1.6.0/), complete changelog can be found [on GitHub](https://github.com/iojs/io.js/blob/v1.x/CHANGELOG.md).
+
+### Notable changes
+
+#### 1.6.1
+
+* **path**: New type-checking on `path.resolve()` [#1153](https://github.com/iojs/io.js/pull/1153) uncovered some edge-cases being relied upon in the wild, most notably `path.dirname(undefined)`. Type-checking has been loosened for `path.dirname()`, `path.basename()`, and `path.extname()` (Colin Ihrig) [#1216](https://github.com/iojs/io.js/pull/1216).
+* **querystring**: Internal optimizations in `querystring.parse()` and `querystring.stringify()` [#847](https://github.com/iojs/io.js/pull/847) prevented `Number` literals from being properly converted via `querystring.escape()` [#1208](https://github.com/iojs/io.js/issues/1208), exposing a blind-spot in the test suite. The bug and the tests have now been fixed (Jeremiah Senkpiel) [#1213](https://github.com/iojs/io.js/pull/1213).
+
+#### 1.6.0
+
+* **node**: a new `-r` or `--require` command-line option can be used to pre-load modules at start-up (Ali Ijaz Sheikh) [#881](https://github.com/iojs/io.js/pull/881).
+* **querystring**: `parse()` and `stringify()` are now faster (Brian White) [#847](https://github.com/iojs/io.js/pull/847).
+* **http**: the `http.ClientRequest#flush()` method has been deprecated and replaced with `http.ClientRequest#flushHeaders()` to match the same change now in Node.js v0.12 as per [joyent/node#9048](https://github.com/joyent/node/pull/9048) (Yosuke Furukawa) [#1156](https://github.com/iojs/io.js/pull/1156).
+* **net**: allow `server.listen()` to accept a `String` option for `port`, e.g. `{ port: "1234" }`, to match the same option being accepted in `net.connect()` as of [joyent/node#9268](https://github.com/joyent/node/pull/9268) (Ben Noordhuis) [#1116](https://github.com/iojs/io.js/pull/1116).
+* **tls**: further work on the reported memory leak although there appears to be a minor leak remaining for the use-case in question, track progress at [#1075](https://github.com/iojs/io.js/issues/1075).
+* **v8**: backport a fix for an integer overflow when `--max_old_space_size` values above `4096` are used (Ben Noordhuis) [#1166](https://github.com/iojs/io.js/pull/1166).
+* **platforms**: the io.js CI system now reports passes on **FreeBSD** and **SmartOS** (_Solaris_).
+* **npm**: upgrade npm to 2.7.1. See [npm CHANGELOG.md](https://github.com/npm/npm/blob/master/CHANGELOG.md#v271-2015-03-05) for details. Summary:
+  * [`6823807`](https://github.com/npm/npm/commit/6823807bba) [#7121](https://github.com/npm/npm/issues/7121) `npm install --save` for Git dependencies saves the URL passed in, instead of the temporary directory used to clone the remote repo. Fixes using Git dependencies when shrinkwwapping. In the process, rewrote the Git dependency caching code. Again. No more single-letter variable names, and a much clearer workflow. ([@othiym23](https://github.com/othiym23))
+  * [`abdd040`](https://github.com/npm/npm/commit/abdd040da9) read-package-json@1.3.2: Provide more helpful error messages when JSON parse errors are encountered by using a more forgiving JSON parser than JSON.parse. ([@smikes](https://github.com/smikes))
+  * [`c56cfcd`](https://github.com/npm/npm/commit/c56cfcd79c) [#7525](https://github.com/npm/npm/issues/7525) `npm dedupe` handles scoped packages. ([@KidkArolis](https://github.com/KidkArolis))
+  * [`4ef1412`](https://github.com/npm/npm/commit/4ef1412d00) [#7075](https://github.com/npm/npm/issues/7075) If you try to tag a release as a valid semver range, `npm publish` and `npm tag` will error early instead of proceeding. ([@smikes](https://github.com/smikes))
+
+### Known Issues
+
+* Possible remaining TLS-related memory leak(s), details at [#1075](https://github.com/iojs/io.js/issues/1075).
