* **zlib**: A bug was discovered where the process would abort if the final part of a zlib decompression results in a buffer that would exceed the maximum length of `0x3fffffff` bytes (~1GiB). This was likely to only occur during buffered decompression (rather than streaming). This is now fixed and will instead result in a thrown `RangeError` (Michaël Zasso) [#1811](https://github.com/nodejs/io.js/pull/1811).

* **http**: Reverts the move of the `client` property of `IncomingMessage` to its prototype. Although undocumented, this property was used and assumed to be an "own property" in the wild, most notably by [request](https://github.com/request/request) which is used by npm. (Michaël Zasso) [#1852](https://github.com/nodejs/io.js/pull/1852).
See https://github.com/nodejs/io.js/labels/confirmed-bug for complete and current list of known issues.
* Some problems with unreferenced timers running during `beforeExit` are still to be resolved. See [#1264](https://github.com/nodejs/io.js/issues/1264).

* Calling `dns.setServers()` while a DNS query is in progress can cause the process to crash on a failed assertion [#894](https://github.com/nodejs/io.js/issues/894)
*`url.resolve` may transfer the auth portion of the url when resolving between two full hosts, see [#1435](https://github.com/nodejs/io.js/issues/1435).
* **node**: Speed-up `require()` by replacing usage of `fs.statSync()` and `fs.readFileSync()` with internal variants that are faster for this use-case and do not create as many objects for the garbage collector to clean up. The primary two benefits are: significant increase in application start-up time on typical applications and better start-up time for the debugger by eliminating almost all of the thousands of exception events. (Ben Noordhuis) [#1801](https://github.com/nodejs/io.js/pull/1801).
* **node**: Resolution of pre-load modules (`-r` or `--require`) now follows the standard `require()` rules rather than just resolving paths, so you can now pre-load modules in node_modules. (Ali Ijaz Sheikh) [#1812](https://github.com/nodejs/io.js/pull/1812).
* **npm**: Upgraded npm to v2.11.0. New hooks for `preversion`, `version`, and `postversion` lifecycle events, some SPDX-related license changes and license file inclusions. See the [release notes](https://github.com/npm/npm/releases/tag/v2.11.0) for full details.

* While not a *breaking change* the 'smalloc' module has been deprecated in anticipation of it becoming unsupportable with a future upgrade to V8 4.4. See [#1451](https://github.com/nodejs/io.js/issues/1451) for further information.
_Note: a new version of the 'url' module was reverted prior to release as it was decided the potential for breakage across the npm ecosystem was too great and that more compatibility work needed to be done before releasing it. See [#1602](https://github.com/nodejs/io.js/pull/1602) for further information._

- REPL history can be persisted across sessions if the `NODE_REPL_HISTORY_FILE` environment variable is set to a user accessible file, `NODE_REPL_HISTORY_SIZE` can set the maximum history size and defaults to `1000` (Chris Dickinson) [#1513](https://github.com/nodejs/io.js/pull/1513)
- The REPL can be placed in to one of three modes using the `NODE_REPL_MODE` environment variable: `sloppy`, `strict` or `magic` (default); the new `magic` mode will automatically run "strict mode only" statements in strict mode (Chris Dickinson) [#1513](https://github.com/nodejs/io.js/pull/1513)
* **V8**: upgrade to 4.2.77.18, see the [ChangeLog](https://chromium.googlesource.com/v8/v8/+/refs/heads/4.2.77/ChangeLog) for full details. Notable items:
- Classes have moved out of staging; the `class` keyword is now usable in strict mode without flags
- Object literal enhancements have moved out of staging; shorthand method and property syntax is now usable (`{ method() { }, property }`)
- Rest parameters (`function(...args) {}`) are implemented in staging behind the `--harmony-rest-parameters` flag
- Computed property names (`{['foo'+'bar']:'bam'}`) are implemented in staging behind the `--harmony-computed-property-names` flag
- Unicode escapes (`'\u{xxxx}'`) are implemented in staging behind the `--harmony_unicode` flag and the `--harmony_unicode_regexps` flag for use in regular expressions

* **C++ API**: Fedor Indutny contributed a feature to V8 which has been backported to the V8 bundled in io.js. `SealHandleScope` allows a C++ add-on author to _seal_ a `HandleScope` to prevent further, unintended allocations within it. Currently only enabled for debug builds of io.js. This feature helped detect the leak in [#1075](https://github.com/nodejs/io.js/issues/1075) and is now activated on the root `HandleScope` in io.js. (Fedor Indutny) [#1395](https://github.com/nodejs/io.js/pull/1395).
* **ARM**: This release includes significant work to improve the state of ARM support for builds and tests. The io.js CI cluster's ARMv6, ARMv7 and ARMv8 build servers are now all (mostly) reporting passing builds and tests.
* ARMv8 64-bit (AARCH64) is now properly supported, including a backported fix in libuv that was mistakenly detecting the existence of `epoll_wait()`. (Ben Noordhuis) [#1365](https://github.com/nodejs/io.js/pull/1365).
* ARMv6: [#1376](https://github.com/nodejs/io.js/issues/1376) reported a problem with `Math.exp()` on ARMv6 (incl Raspberry Pi). The culprit is erroneous codegen for ARMv6 when using the "fast math" feature of V8. `--nofast_math` has been turned on for all ARMv6 variants by default to avoid this, fast math can be turned back on with `--fast_math`. (Ben Noordhuis) [#1398](https://github.com/nodejs/io.js/pull/1398).
* Tests: timeouts have been tuned specifically for slower platforms, detected as ARMv6 and ARMv7. (Roman Reiss) [#1366](https://github.com/nodejs/io.js/pull/1366).
* **npm**: Upgrade npm to 2.7.6. See the [release notes](https://github.com/npm/npm/releases/tag/v2.7.6) for details. Summary:
* [`b747593`](https://github.com/npm/npm/commit/b7475936f473f029e6a027ba1b16277523747d0b)[#7630](https://github.com/npm/npm/issues/7630) Don't automatically log all git failures as errors. `maybeGithub` needs to be able to fail without logging to support its fallback logic. ([@othiym23](https://github.com/othiym23))
* [`78005eb`](https://github.com/npm/npm/commit/78005ebb6f4103c20f077669c3929b7ea46a4c0d)[#7743](https://github.com/npm/npm/issues/7743) Always quote arguments passed to `npm run-script`. This allows build systems and the like to safely escape glob patterns passed as arguments to `run-scripts` with `npm run-script <script> -- <arguments>`. This is a tricky change to test, and may be reverted or moved to `npm@3` if it turns out it breaks things for users. ([@mantoni](https://github.com/mantoni))
* [`da015ee`](https://github.com/npm/npm/commit/da015eee45f6daf384598151d06a9b57ffce136e)[#7074](https://github.com/npm/npm/issues/7074) `read-package-json@1.3.3`: `read-package-json` no longer caches `package.json` files, which trades a very small performance loss for the elimination of a large class of really annoying race conditions. See [#7074](https://github.com/npm/npm/issues/7074) for the grisly details. ([@othiym23](https://github.com/othiym23))

* **npm**: upgrade npm to 2.7.5. See [npm CHANGELOG.md](https://github.com/npm/npm/blob/master/CHANGELOG.md#v275-2015-03-26) for details. Includes two important security fixes. Summary:
* **openssl**: preliminary work has been done for an upcoming upgrade to OpenSSL 1.0.2a [#1325](https://github.com/nodejs/io.js/pull/1325) (Shigeki Ohtsu). See [#589](https://github.com/nodejs/io.js/issues/589) for additional details.
* **timers**: a minor memory leak when timers are unreferenced was fixed, alongside some related timers issues [#1330](https://github.com/nodejs/io.js/pull/1330) (Fedor Indutny). This appears to have fixed the remaining leak reported in [#1075](https://github.com/nodejs/io.js/issues/1075).
* **android**: it is now possible to compile io.js for Android and related devices [#1307](https://github.com/nodejs/io.js/pull/1307) (Giovanny Andres Gongora Granada).
* Some problems with unreferenced timers running during `beforeExit` are still to be resolved. See [#1264](https://github.com/nodejs/io.js/issues/1264).

* **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/nodejs/io.js/issues/1058), fixed in [#1063](https://github.com/nodejs/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/nodejs/io.js/pull/848) (Vladimir Kurchatkin).
-`Timer#close()` is now properly idempotent [#1288](https://github.com/nodejs/io.js/issues/1288) (Petka Antonov).
-`setTimeout()` will only run the callback once now after an `unref()` during the callback [#1231](https://github.com/nodejs/io.js/pull/1231) (Roman Reiss).
- NOTE: there are still other unresolved concerns with the timers code, such as [#1152](https://github.com/nodejs/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/nodejs/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`.

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))

* **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/nodejs/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/nodejs/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.
* Possible small memory leak(s) may still exist but have yet to be properly identified, details at [#1075](https://github.com/nodejs/io.js/issues/1075).

* **path**: New type-checking on `path.resolve()` [#1153](https://github.com/nodejs/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/nodejs/io.js/pull/1216).
* **querystring**: Internal optimizations in `querystring.parse()` and `querystring.stringify()` [#847](https://github.com/nodejs/io.js/pull/847) prevented `Number` literals from being properly converted via `querystring.escape()` [#1208](https://github.com/nodejs/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/nodejs/io.js/pull/1213).

* **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/nodejs/io.js/pull/881).
* **querystring**: `parse()` and `stringify()` are now faster (Brian White) [#847](https://github.com/nodejs/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/nodejs/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/nodejs/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/nodejs/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/nodejs/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.

* [`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))
* [`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))

* **tls**: The reported TLS memory leak has been at least partially resolved via various commits in this release. Current testing indicated that there _may_ still be some leak problems. Track complete progress at [#1075](https://github.com/nodejs/io.js/issues/1075).
* **http**: Fixed an error reported at [joyent/node#9348](https://github.com/joyent/node/issues/9348) and [npm/npm#7349](https://github.com/npm/npm/issues/7349). Pending data was not being fully read upon an `'error'` event leading to an assertion failure on `socket.destroy()`. (Fedor Indutny) [#1103](https://github.com/nodejs/io.js/pull/1103)
* Possible remaining TLS-related memory leak(s), details at [#1075](https://github.com/nodejs/io.js/issues/1075).

* **buffer**: New `Buffer#indexOf()` method, modelled off [`Array#indexOf()`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/indexOf). Accepts a String, Buffer or a Number. Strings are interpreted as UTF8. (Trevor Norris) [#561](https://github.com/nodejs/io.js/pull/561)
* **fs**: `options` object properties in `'fs'` methods no longer perform a `hasOwnProperty()` check, thereby allowing options objects to have prototype properties that apply. (Jonathan Ong) [#635](https://github.com/nodejs/io.js/pull/635)
* **tls**: A likely TLS memory leak was reported by PayPal. Some of the recent changes in **stream_wrap** appear to be to blame. The initial fix is in [#1078](https://github.com/nodejs/io.js/pull/1078), you can track the progress toward closing the leak at [#1075](https://github.com/nodejs/io.js/issues/1075) (Fedor Indutny).
* **npm**: Upgrade npm to 2.7.0. See [npm CHANGELOG.md](https://github.com/npm/npm/blob/master/CHANGELOG.md#v270-2015-02-26) for details including why this is a semver-minor when it could have been semver-major. Summary:

outdated`) now defaults to `--depth=0`. This also has the excellent but unexpected effect of making `npm update -g` work the way almost everyone wants it to. See the [docs for
* Windows support has some outstanding failures that have not been properly picked up by the io.js CI system due to a combination of factors including human, program and Jenkins errors. See [#1005](https://github.com/nodejs/io.js/issues/1005) for details & discussion. Expect these problems to be addressed ASAP.
* Surrogate pair in REPL can freeze terminal [#690](https://github.com/nodejs/io.js/issues/690)
* Not possible to build io.js as a static library [#686](https://github.com/nodejs/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/nodejs/io.js/issues/760) and fix in [#774](https://github.com/nodejs/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/nodejs/io.js/issues/894)

_Note: version **1.4.0** was tagged and built but not released. A libuv bug was discovered in the process so the release was aborted. The tag was straight after [`a558cd0a61`](https://github.com/nodejs/io.js/commit/a558cd0a61) but has since been removed. We have jumped to 1.4.1 to avoid confusion._
* **process** / **promises**: An `'unhandledRejection'` event is now emitted on `process` whenever a `Promise` is rejected and no error handler is attached to the `Promise` within a turn of the event loop. A `'rejectionHandled'` event is now emitted whenever a `Promise` was rejected and an error handler was attached to it later than after an event loop turn. See the [process](https://iojs.org/api/process.html) documentation for more detail. [#758](https://github.com/nodejs/io.js/pull/758) (Petka Antonov)
* **streams**: you can now use regular streams as an underlying socket for `tls.connect()` [#926](https://github.com/nodejs/io.js/pull/926) (Fedor Indutny)
* **http**: A new `'abort'` event emitted when a `http.ClientRequest` is aborted by the client. [#945](https://github.com/nodejs/io.js/pull/945) (Evan Lucas)
* **V8**: Upgrade V8 to 4.1.0.21. Includes an embargoed fix, details should be available at https://code.google.com/p/chromium/issues/detail?id=430201 when embargo is lifted. A breaking ABI change has been held back from this upgrade, possibly to be included when io.js merges V8 4.2. See [#952](https://github.com/nodejs/io.js/pull/952) for discussion.
* **npm**: Upgrade npm to 2.6.0. Includes features to support the new registry and to prepare for `npm@3`. See [npm CHANGELOG.md](https://github.com/npm/npm/blob/master/CHANGELOG.md#v260-2015-02-12) for details. Summary:

- Simpler stream construction, see [readable-stream/issues#102](https://github.com/nodejs/readable-stream/issues/102) for details. This extends the streams base objects to make their constructors accept default implementation methods, reducing the boilerplate required to implement custom streams. An updated version of readable-stream will eventually be released to match this change in core. (@sonewman)
-`lookup()` now supports an `'all'` boolean option, default to `false` but when turned on will cause the method to return an array of *all* resolved names for an address, see, [#744](https://github.com/nodejs/io.js/pull/744) (@silverwind)
- Remove `prototype` property comparison in `deepEqual()`, considered a bugfix, see [#636](https://github.com/nodejs/io.js/pull/636) (@vkurchatkin)
- Introduce a `deepStrictEqual()` method to mirror `deepEqual()` but performs strict equality checks on primitives, see [#639](https://github.com/nodejs/io.js/pull/639) (@vkurchatkin)
- Add [LTTng](http://lttng.org/) (Linux Trace Toolkit Next Generation) when compiled with the `--with-lttng` option. Trace points match those available for DTrace and ETW. [#702](https://github.com/nodejs/io.js/pull/702) (@thekemkid)
- New **Errors** page discussing JavaScript errors, V8 specifics, and io.js specific error details. (@chrisdickinson)
* **npm** upgrade to 2.5.1, short changelog:
- [npm/0e8d473](https://github.com/npm/npm/commit/0e8d4736a1cbdda41ae8eba8a02c7ff7ce80c2ff) [#7281](https://github.com/npm/npm/issues/7281) `npm-registry-mock@1.0.0`: Clean up API, set `connection: close`, which makes tests pass on io.js 1.1.x.

- The V8 JavaScript engine bundled with io.js was upgraded dramatically, from version 3.14.5.9 in Node.js v0.10.35 and 3.26.33 in Node.js v0.11.14 to 3.31.74.1 for io.js v1.0.0. This brings along many fixes and performance improvements, as well as additional support for new ES6 language features! For more information on this, check out [the io.js ES6 page](https://iojs.org/es6.html).
- Added `buf.writeUIntLE`, `buf.writeUIntBE`, `buf.writeIntLE`, `buf.writeIntBE`, `buf.readUIntLE`, `buf.readUIntBE`, `buf.readIntLE` and `buf.readIntBE` methods that read and write value up to 6 bytes.
- Updated the output of `buffer.toJSON()` to not be the same as an array. Instead it is an object specifically tagged as a buffer, which can be recovered by passing it to (a new overload of) the `Buffer` constructor.
- Added synchronous counterparts for the child process functions: `child_process.spawnSync`, `child_process.execSync`, and `child_process.execFileSync`.
- Added chaining support to `EventEmitter.setMaxListeners`.
- Updated `require('events')` to return the `EventEmitter` constructor, allowing the module to be used like `var EventEmitter = require('events')` instead of `var EventEmitter = require('events').EventEmitter`.
- Added MAC addresses, netmasks and scope IDs for IPv6 addresses to `os.networkInterfaces` method output.
- Updated `os.tmpdir` on Windows to use the `%SystemRoot%` or `%WINDIR%` environment variables instead of the hard-coded value of `c:\windows` when determining the temporary directory location.
data is returned as a result of a `.read` call that data will *also* be emitted on the `"data"` event.
As before, adding a listener for the `"readable"` or `"data"` event will start flowing the stream; as
will piping to another stream.
#### Writable streams
The ability to "bulk write" to underlying resources has been added to `Writable` streams. For stream
implementers, one can signal that a stream is bulk-writable by specifying a [_writev](https://iojs.org/api/stream.html#stream_writable_writev_chunks_callback) method.
Bulk writes will occur in two situations:
1. When a bulk-writable stream is clearing its backlog of buffered write requests,
2. or if an end user has made use of the new `.cork()` and `.uncork()` API methods.
`.cork` and `.uncork` allow the end user to control the buffering behavior of writable streams separate
from exerting backpressure. `.cork` indicates that the stream should accept new writes (up to `highWaterMark`),
while `.uncork` resets that behavior and attempts to bulk-write all buffered writes to the underlying resource.
The only core stream API that **currently** implements `_writev` is `net.Socket`.
In addition to the bulk-write changes, the performance of repeated small writes to non-bulk-writable streams
(such as `fs.WriteStream`) has been drastically improved. Users piping high volume log streams to disk should
see an improvement.
For a detailed overview of how streams3 interact, [see this diagram](https://cloud.githubusercontent.com/assets/37303/5728694/f9a3e300-9b20-11e4-9e14-a6938b3327f0.png).
The `vm` module has been rewritten to work better, based on the excellent [Contextify](https://github.com/brianmcd/contextify) native module. All of the functionality of Contextify is now in core, with improvements!
- Added `vm.isContext(object)` method to determine whether `object` has been contextified.
- Added `vm.runInDebugContext(code)` method to compile and execute `code` inside the V8 debug context.
- Updated `vm.createContext(sandbox)` to "contextify" the sandbox, making it suitable for use as a global for `vm` scripts, and then return it. It no longer creates a separate context object.
- Updated most `vm` and `vm.Script` methods to accept an `options` object, allowing you to configure a timeout for the script, the error display behavior, and sometimes the filename (for stack traces).
- Updated the supplied sandbox object to be used directly as the global, remove error-prone copying of properties back and forth between the supplied sandbox object and the global that appears inside the scripts run by the `vm` module.
In general it is recommended that you use [NAN](https://github.com/rvagg/nan) as a compatibility layer for your addons. This will also help with future changes in the V8 and Node/io.js C++ API. Most of the following changes are already handled by NAN-specific wrappers.
- Exposed method signature has changed from `Handle<Value> Method(const Arguments& args)` to `void Method(const v8::FunctionCallbackInfo<Value>& args)` with the newly introduced `FunctionCallbackInfo` also taking the return value via `args.GetReturnValue().Set(value)` instead of `scope.Close(value)`, `Arguments` has been removed.
- Similar changes have been made to property enumerators, property deleters, property query, index getter, index setter, index enumerator, index deleter, index query.
- V8 objects instantiated in C++ now require an `Isolate*` argument as the first argument. In most cases it is OK to simply pass `v8::Isolate::GetCurrent()`, e.g. `Date::New(Isolate::GetCurrent(), time)`, or `String::NewFromUtf8(Isolate::GetCurrent(), "foobar")`.
-`HandleScope scope` now requires an `Isolate*` argument, i.e. `HandleScope scope(isolate)`, in most cases `v8::Isolate::GetCurrent()` is OK.
- Similar changes have been made to `Locker` and `Unlocker`.
- V8 objects that need to "escape" a scope should be enclosed in a `EscapableHandleScope` rather than a `HandleScope` and should be returned with `scope.Escape(value)`.
- Exceptions are now thrown from isolates with `isolate->ThrowException(ExceptionObject)`.
-`Context::GetCurrent()` must now be done on an isolate, e.g. `Isolate::GetCurrent()->GetCurrentContext()`.
-`String::NewSymbol()` has been removed, use plain strings instead.
-`String::New()` has been removed, use `String::NewFromUtf8()` instead.
-`Persistent` objects no longer inherit from `Handle` and cannot be instantiated with another object. Instead, the `Persistent` should simply be declared, e.g. `Persistent<Type> handle` and then have a `Local` assigned to it with `handle.Reset(isolate, value)`. To get a `Local` from a `Persistent` you must instantiate it as the argument, i.e. `Local::New(Isolate*, Persistent)`.
