Oracle Java 10 released with many new features

Oracle announces production ready Java SE 10 (JDK 10) obsoleting Java 9, which arrived just six months ago.

Some of the features in Java 10 -

Local-variable type inference: enhances the Java language to extend type inference to declarations of local variables with initializers.
Parallel Full GC for G1: improves G1 worst-case latencies by making the full GC parallel.
Application Class-Data Sharing: optimizes startup time and footprint by extending the existing Class-Data Sharing (“CDS”) feature to allow application classes to be placed in the shared archive.
Experimental Java-Based JIT Compiler: enables the Java-based JIT compiler, Graal, to be used as an experimental JIT compiler on the Linux/x64 platform
Thread-Local Handshakes: a way to execute a callback on threads without performing a global VM safepoint.
Heap Allocation on Alternative Memory Devices: Enables the HotSpot VM to allocate the Java object heap on an alternative memory device, such as an NV-DIMM, specified by the user
Time-Based Release Versioning: Revises the version-string scheme of the Java SE Platform and the JDK, and related versioning information, for present and future time-based release models.
