Node v12.16.1 (LTS)

Myles Borins

Notable changes

Node.js 12.16.0 included 6 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.

Process Cleanup Changed Introduced WASM-Related Assertion:

A change during Node.js process cleanup led to a crash in combination with specific usage of WASM. This has been fixed by partially reverted said change. A regression test and a full fix are being worked on and will likely be included in future 12.x and 13.x releases.

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 reland 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.

New Enumerable Read-Only Property on EventEmitter breaks @types/extend

A new property for enumerating events was added to the EventEmitter class. This broke existing code that was using the @types/extend module for extending classses as @types/extend was attemping to write over the existing field which the new change made read-only. As this is the first property on EventEmitter that is read-only this feature could be considered Semver-Major. The new feature has been reverted but could re-land in a future Semver-Minor release if a non breaking way of applying it is found.

Exceptions in the HTTP parser were not emitting an uncaughtException

A refactoring to Node.js interanls resulted in a bug where errors in the HTTP parser were not being emitted by process.on('uncaughtException') when the async_hooks after hook exists. The fix to this bug has been included in this release.
