JDK 17, the reference implementation of Java 17, is now Generally
Available. We shipped build 35 as the first Release Candidate of
JDK 17 on 6 August, and no P1 bugs have been reported since then.
Build 35 is therefore now the GA build, ready for production use.
GPL-licensed OpenJDK builds from Oracle are available here:
https://jdk.java.net/17
Builds from other vendors will no doubt be available soon.
This release includes fourteen JEPs [1]:
306: Restore Always-Strict Floating-Point Semantics
356: Enhanced Pseudo-Random Number Generators
382: New macOS Rendering Pipeline
391: macOS/AArch64 Port
398: Deprecate the Applet API for Removal
403: Strongly Encapsulate JDK Internals
406: Pattern Matching for switch (Preview)
407: Remove RMI Activation
409: Sealed Classes
410: Remove the Experimental AOT and JIT Compiler
411: Deprecate the Security Manager for Removal
412: Foreign Function & Memory API (Incubator)
414: Vector API (Second Incubator)
415: Context-Specific Deserialization Filters
along with hundreds of smaller enhancements and almost two thousand
bug fixes.
JDK 17 will be a long-term-support (LTS) release from most vendors,
including Oracle. If you’re upgrading from the previous LTS release,
JDK 11, then you have many more JEPs to look forward to, summarized
here:

plus thousands of smaller enhancements and almost ten thousand bug
fixes.
Thank you to everyone who contributed this release, whether by
designing and implementing features or enhancements, by fixing bugs,
or by downloading and testing the early-access builds!
