npm 7 (https://github.com/nodejs/node/pull/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
(https://github.com/nodejs/node/pull/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 (https://github.com/nodejs/node/pull/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 (https://github.com/nodejs/node/pull/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)
