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:

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

plus thousands of smaller enhancements and almost ten thousand bug

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!
