This document specifies API features, enhancements, clarifications, and bug fixes. The specifications of those changes are contained in two accompanying documents: Annex 1 is the complete Java SE 18.3 API Specification and Annex 2 is an annotated API specification showing the exact differences relative to Java SE 9.

This Specification includes the Java SE 18.3 Editions of The Java Language Specification and The Java Virtual Machine Specification in Annex 3. The Java SE 18.3 Editions contain all corrections and clarifications made since the Java SE 9 Editions, as well as additions for new features.

The Final Release of this Specification is expected to include all of the currently described features and updates; however, further changes may be forthcoming. For example, the Expert Group could determine that a feature is not yet ready for standardization.
