 Finalized Features:

Virtual Threads (Project Loom):
Lightweight threads that simplify writing high-throughput, scalable applications by reducing the overhead of creating and managing threads. 
Record Patterns:
Enable pattern matching for record deconstruction, making it easier to extract data from records. 
Pattern Matching for Switch:
Enhances the switch statement, allowing for more complex pattern matching and reducing boilerplate code. 
Sequenced Collections:
Introduces interfaces like SequencedCollection, SequencedSet, and SequencedMap to provide a consistent way to work with ordered collections and access their first and last elements. 
Foreign Function & Memory API (Final):
Provides a stable API for interacting with native code, offering a more efficient and manageable way to integrate with non-Java code.
