Hi Uwe & Dawid, **
*OpenJDK 17 Early Access build 23 is now available at
*_*https://jdk.java.net/17* <https://jdk.java.net/17>_
* These early-access , open-source builds are provided under the
o GNU General Public License, version 2, with the Classpath
Exception <https://openjdk.java.net/legal/gplv2+ce.html>
* JEPs targeted to JDK 17, so far:
o JEP 356: _Enhanced Pseudo-Random Number Generators
<https://openjdk.java.net/jeps/356>_
o JEP 382: _New macOS Rendering Pipeline
<https://openjdk.java.net/jeps/382>_
o JEP 391: _macOS/AArch64 Port <https://openjdk.java.net/jeps/391>_
o JEP 398: _Deprecate the Applet API for Removal
<https://openjdk.java.net/jeps/398>_
o JEP 409: _Sealed Classes <https://openjdk.java.net/jeps/409>_
o JEP 410: _Remove the Experimental AOT and JIT Compiler
<https://openjdk.java.net/jeps/410>_
o JEP 412: _Foreign Function & Memory API (Incubator)
<https://openjdk.java.net/jeps/412>_
o JEP 414: _Vector API (Second Incubator)
<https://openjdk.java.net/jeps/414>_
* Release Notes are available at
_https://jdk.java.net/17/release-notes
<https://jdk.java.net/17/release-notes>_
* Changes in recent builds that maybe of interest:
o Build 23
+ JDK-8243287: Removal of Unsafe::defineAnonymousClass.
o Build 22
+ *JDK-8266369: New implementation of
java.nio.channels.Selector on Microsoft Windows. *
o Build 21
+ *JDK-8196415: JARs signed with SHA-1 algorithms are
restricted by default.*
+ *JDK-8266858: macOS on ARM early access available.*
# The ARM port should behave similarly to the Intel port.
There are no known feature differences.
# When reporting issues on macOS please specify if using
ARM or x64.
*We need your help in testing new Selector implementation on Windows [1]:*
* The implementation of the Selector API on Windows has been replaced
in JDK 17 b22 with a new more scalable implementation [2].
* The old select based Selector implementation has been the default
since Java 1.4 (2002) so replacing it is a significant change.
* It would be really helpful to get more testing of the new
implementation before the fork for Rampdown Phase One on June 10th.
*Other Topics which might be of Interest:*
* Updates to JEP 411: Deprecate the Security Manager for Removal |
