A new Standard for Ada has been published as ISO/IEC 8652:2023. This Standard is informally known as Ada 2022 (it was originally expected to be published in 2022, but the gears of standardization turn slowly). This is a formal revision to Ada, integrating the previously separate changes from earlier Technical Corrigenda and Editions of the Standard, along with a variety of new features and changes. Ada continues to evolve with software theory and practice, and undoubtedly there will be further improvements in the future.
Below is an brief survey of the more important enhancements in Ada 2022. These enhancements can be grouped as follows:
An Overview of Ada 2022

Ada 2022 Language Reference Manual
The actual text of the Ada 2022 edition of the Ada Reference Manual (the source of the Standard) is available here, in various forms.
These are the original design documents for each change to the language. Each one of the enhancements mentioned above corresponds to one or more Ada Issues (AIs). For further details, please refer to the database at the Ada Information Clearinghouse (see http://www.ada-auth.org/AI12-SUMMARY.HTML where the interested reader will find up-to-date descriptions and a full list of Amendment AIs, along with their status, motivation and ongoing discussions).
