ECMAScript Modules - Experimental Warning Removal:

- module: remove experimental modules warning
  (Guy Bedford) [nodejs#31974](nodejs#31974)

In Node.js 13 we removed the need to include the --experimental-modules
flag, but when running EcmaScript Modules in Node.js, this would still
result in a warning ExperimentalWarning: The ESM module loader is
experimental.

As of Node.js 14 there is no longer this warning when using ESM in
Node.js. However, the ESM implementation in Node.js remains
experimental. As per our stability index: “The feature is not subject
to Semantic Versioning rules. Non-backward compatible changes or
removal may occur in any future release.” Users should be cautious when
using the feature in production environments.

Please keep in mind that the implementation of ESM in Node.js differs
from the developer experience you might be familiar with. Most
transpilation workflows support features such as optional file
extensions or JSON modules that the Node.js ESM implementation does not
support. It is highly likely that modules from transpiled environments
will require a certain degree of refactoring to work in Node.js. It is
worth mentioning that many of our design decisions were made with two
primary goals. Spec compliance and Web Compatibility. It is our belief
that the current implementation offers a future proof model to
authoring ESM modules that paves the path to Universal JavaScript.
Please read more in our documentation.

The ESM implementation in Node.js is still experimental but we do believe
that we are getting very close to being able to call ESM in Node.js
“stable”. Removing the warning is a huge step in that direction.

New V8 ArrayBuffer API:

* **src**: migrate to new V8 ArrayBuffer API
  (Thang Tran) [nodejs#30782](nodejs#30782)

Multiple ArrayBuffers pointing to the same base address are no longer
allowed by V8. This may impact native addons.

Toolchain and Compiler Upgrades:

- (SEMVER-MAJOR) build: update macos deployment target to 10.13 for 14.x
  (AshCripps)[nodejs#32454](nodejs#32454)
- (SEMVER-MAJOR) doc: update cross compiler machine for Linux armv7
  (Richard Lau) [nodejs#32812](nodejs#32812)
- (SEMVER-MAJOR) doc: update Centos/RHEL releases use devtoolset-8
  (Richard Lau) [nodejs#32812](nodejs#32812)
- (SEMVER-MAJOR) doc: remove SmartOS from official binaries
  (Richard Lau) [nodejs#32812](nodejs#32812)
- (SEMVER-MAJOR) win: block running on EOL Windows versions
  (João Reis) [nodejs#31954](nodejs#31954)

It is expected that there will be an ABI mismatch on ARM between the
Node.js binary and native addons. Native addons are only broken if they
interact with `std::shared_ptr`. This is expected to be fixed in a
later version of Node.js 14.
- [nodejs#30786](nodejs#30786)

Update to V8 8.1:

- (SEMVER-MAJOR) deps: update V8 to 8.1.307.20
  (Matheus Marchini) [nodejs#32116](nodejs#32116)

Other Notable Changes:

- cli, report: move --report-on-fatalerror to stable
  (Colin Ihrig) [nodejs#32496](nodejs#32496)
- deps: upgrade to libuv 1.37.0
  (Colin Ihrig) [nodejs#32866](nodejs#32866)
- fs: add fs/promises alias module
  (Gus Caplan) [nodejs#31553](nodejs#31553)
