emitting 'error' was a bug

Marking as semver major since minor differences in behavior probably exists.

_transformState is no longer used since Transform was simplified. Refs: nodejs#32763

jasnell · 2020-04-28T14:54:48Z

This really should have done a runtime deprecation for _transformState rather than removing it entirely. It's relatively low impact given that, as a semver-major, this won't be pulled in to any release until 15.0.0 but for 14.x we should add a proper deprecation for _transformState.

One of the big changes in npm 7 is that peer dependencies are now installed by default. Throw On Unhandled Rejections (#33021): As of Node.js 15, the default mode for `unhandledRejection` is changed to `throw` (from `warn`). In `throw` mode, if an `unhandledRejection` hook is not set, the `unhandledRejection` is raised as an uncaught exception. Users that have an `unhandledRejection` hook should see no change in behavior, and it’s still possible to switch modes using the `--unhandled-rejections=mode` process flag. QUIC (#32379): Node.js 15 comes with experimental support QUIC, which can be enabled by compiling Node.js with the `--experimental-quic` configuration flag. The Node.js QUIC implementation is exposed by the core `net` module. V8 8.6 (#35415): The V8 JavaScript engine has been updated to V8 8.6 (V8 8.4 is the latest available in Node.js 14). Along with performance tweaks and improvements the V8 update also brings the following language features: * `Promise.any()` (from V8 8.5) * `AggregateError` (from V8 8.5) * `String.prototype.replaceAll()` (from V8 8.5) * Logical assignment operators `&&=`, `||=`, and `??=` (from V8 8.5) Other Notable Changes: -
