2020-02-14, Version 12.16.1 'Erbium' (LTS)

Notable changes:

Node.js 12.16.0 included 3 regressions that are being fixed in this release

Accidental Unflagging of Self Resolving Modules:

12.16.0 included a large update to the ESM implementation. One of
the new features, Self Referential Modules, was accidentally released
without requiring the `--experimental-modules` flag. This release is
being made to appropriately flag the feature.

Isolate Disposal Order Change Introduced WASM Assertion:

A change in the order of Isolate Disposal created an assertion
error in WASM usage in V8. This was not present on 13.x or higher as
they use a newer version of V8. The change was reverted. A
regression test and fix are being worked on and will likely be
included in a future 12.x release

Use Largepages Runtime Option Introduced Linking Failure:

A Semver-Minor change to introduce `--use-largepages` as a runtime
option introduced a linking failure. This had been fixed in master
but regressed as the fix has not yet gone out in a Current release.
The feature has been reverted, but will be able to re-land with a fix
in a future Semver-Minor release.

Async Hooks was Causing an Exception When Handling Errors:

Changes in async hooks internals introduced a case where an internal
api call could be called with undefined causing a process to crash.
The change to async hooks was reverted. A regression test and fix has
been proposed and the change could re land in a future Semver-Patch
release if the regression is reliably fixed.
