Due to release process failures, Node.js v10.20.0 shipped with source
and header tarballs that did not properly match the final release
commit that was used to build the binaries. We recommend that Node.js
v10.20.0 not be used, particularly in any applications using native
add-ons or where compiling Node.js from source is involved.

Node.js v10.20.1 is a clean release with the correct sources and is
strongly recommended in place of v10.20.0.

This avoids an edge-case memory leak.

This simplifies the code significantly, and removes the dependency of
the inspector code on the availability of a `MultiIsolatePlatform`
(by removing the dependency on a platform altogether).

It also fixes a memory leak that occurs when `RequestInterrupt()`
is used, but the interrupt handler is never called before the Isolate
is destroyed.

One downside is that this leads to a slight change in timing, because
inspector messages are not dispatched in a re-entrant way. This means
having to harden one test to account for that possibility by making
sure that the stack is always clear through a `setImmediate()`.
This does not affect the assertion made by the test, which is that
messages will not be delivered synchronously while other code is
executing.

macOS package notarization and a change in builder configuration

The macOS binaries for this release, and future 10.x releases, are now
being compiled on macOS 10.15 (Catalina) with Xcode 11 to support
package notarization, a requirement for installing .pkg files on macOS
10.15 and later. Previous builds of Node.js 10.x were compiled on macOS
10.10 (Yosemite) with a minimum deployment target of macOS 10.7 (Lion).
As binaries are still being compiled to support a minimum of macOS 10.7
(Lion) we do not anticipate this having a negative impact on Node.js
10.x users with older versions of macOS.
