Notable changes:
* 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 and is now
activated on the root HandleScope in io.js. (Fedor Indutny) #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.
- ARMv6: #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.
- Tests: timeouts have been tuned specifically for slower platforms,
detected as ARMv6 and ARMv7. (Roman Reiss) #1366.
* npm: Upgrade npm to 2.7.6. See the release notes
(https://github.com/npm/npm/releases/tag/v2.7.6) for details.
* **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/iojs/io.js/issues/1075) and is now activated on the root `HandleScope` in io.js.

* **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))
