is controlled by the MBEDTLS_SSL_PROTO_TLS1_3 configuration option.
The development of the TLS 1.3 protocol is based on the TLS 1.3 prototype
located at https://github.com/hannestschofenig/mbedtls. The prototype is
itself based on a version of the development branch that we aim to keep as
recent as possible (ideally the head) by merging regularly commits of the
development branch into the prototype. The section "Prototype upstreaming
status" below describes what remains to be upstreamed.

Prototype upstreaming status
----------------------------
The following parts of the TLS 1.3 prototype remain to be upstreamed:
- New TLS Message Processing Stack (MPS)
The TLS 1.3 prototype is developed alongside a rewrite of the TLS messaging layer,
encompassing low-level details such as record parsing, handshake reassembly, and
DTLS retransmission state machine.
MPS has the following components:
- Layer 1 (Datagram handling)
- Layer 2 (Record handling)
- Layer 3 (Message handling)
- Layer 4 (Retransmission State Machine)
- Reader (Abstracted pointer arithmetic and reassembly logic for incoming data)
- Writer (Abstracted pointer arithmetic and fragmentation logic for outgoing data)
Of those components, the following have been upstreamed
as part of `MBEDTLS_SSL_PROTO_TLS1_3`:
- Reader ([`library/mps_reader.h`](../../library/mps_reader.h))
