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

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.

Notable changes: Deprecations and Removals: - **build**: remove --build-v8-with-gn configure option (Yang Guo) (#27576) - **build**: drop support for VS2017 (Michaël Zasso) (#33694) - **doc**: move DEP0018 to End-of-Life (Rich Trott) (#35316) - **fs**: deprecation warning on recursive rmdir (Ian Sutherland) (#35562) - **lib**: add EventTarget-related browser globals (Anna Henningsen) (#35496) - **net**: remove long deprecated server.connections property (James M Snell) (#33647) - **repl**: remove deprecated repl.memory function (Ruben Bridgewater) (#33286) - **repl**: remove deprecated repl.turnOffEditorMode() function (Ruben Bridgewater) (#33286) - **repl**: remove deprecated repl.parseREPLKeyword() function (Ruben Bridgewater) (#33286) - **repl**: remove deprecated bufferedCommand property (Ruben Bridgewater) (#33286) - **repl**: remove deprecated .rli (Ruben Bridgewater) (#33286) - **src**: remove deprecated node debug command (James M Snell) (#33648) - **timers**: introduce timers/promises (James M Snell) (#33950) - **util**: change default value of `maxStringLength` to 10000 (unknown) (#32744) - **wasi**: drop --experimental-wasm-bigint requirement (Colin Ihrig) (#35415) npm 7 (#35631): Node.js 15 comes with a new major release of npm, npm 7. npm 7 comes with many new features - including npm workspaces and a new package-lock.json format. npm 7 also includes yarn.lock file support. 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: -
