Two new interfaces, [TextAppender] and [BinaryAppender], have been
introduced to append the textual or binary representation of an object
to a byte slice. These interfaces provide the same functionality as
[TextMarshaler] and [BinaryMarshaler], but instead of allocating a new slice

## Supported Versions

We support the past two Go releases (for example, Go 1.17.x and Go 1.18.x when Go 1.18.x is the latest stable release).

See https://go.dev/wiki/Go-Release-Cycle and in particular the
[Release Maintenance](https://go.dev/wiki/Go-Release-Cycle#release-maintenance)
part of that page.

// --------------------
// Continuation messages contain two headers, as follows:
