>
>   Summary: Enhance the security of Java applications that require secure
>   network communication by implementing hybrid key exchange algorithms
>   for TLS 1.3.  Such algorithms defend against future quantum computing
>   attacks by combining a quantum-resistant algorithm with a traditional
>   algorithm.  Applications that use the javax.net.ssl APIs will benefit
>   from these improved algorithms by default, without change to existing
>   code.

> I’ll target this JEP to JDK 27.

Hearing no objections, I’ve targeted this JEP to JDK 27.
