  * Schedule: *JDK 16 Rampdown Phase One Starts on 2020/12/10 [1] *

  * Features [1]: Most recent Integrations:
      o Integrated JEP 389: Foreign Linker API (Incubator)
        <https://openjdk.java.net/jeps/389> with this release.
          + JEP 389 introduces an API that offers statically-typed,
            pure-Java access to native code.
          + This API, together with the JEP 383
            <https://openjdk.java.net/jeps/383>, will considerably
            simplify the otherwise error-prone process of binding to a
            native library.

The Java Cryptographic Roadmap has been updated [3]:

  * Distrust TLS 1.0 and TLS 1.1 by default
      o TLS protocol versions 1.0 and 1.1 are no longer considered
        secure and have been superseded by more secure and modern
        versions (TLS 1.2 and 1.3). This change has been integrated with
        JDK 16 Early Access build 26.
  * Upgrade of default algorithms used to encrypt PKCS12 keystores
      o The new algorithms are based on AES-256 and SHA-256 and are
        stronger than the old algorithms which were based on RC2,
        DESede, and SHA-1.This change is already included in JDK 16
        Early Access build 23.
