Please review this change to increase the default Diffie-Hellman group size used in the key exchange method of TLS_DHE cipher suites from 1024-bit to 2048-bit. This issue does not affect TLS 1.3.

See the CSR for more details on the rationale for this change and the expected compatibility risk (low).
