Additional sources of information about the APIs, features, and options deprecated in Java SE 15 and JDK 15 include:

- The [Deprecated API](https://cr.openjdk.java.net/~iris/se/15/latestSpec/api/deprecated-list.html) page identifies all deprecated APIs including those deprecated in Java SE 15.
- The [Java SE 15 ( JSR 390)](https://cr.openjdk.java.net/~iris/se/15/latestSpec/) specification specification documents changes to the specification made between Java SE 14 and Java SE 15 that include the identification of deprecated APIs and features not described here.
- [JEP 277: Enhanced Deprecation](http://openjdk.java.net/jeps/277) provides a detailed description of the deprecation policy. You should be aware of the updated policy described in this document.

You should be aware of the contents in those documents as well as the items described in this release notes page.

The descriptions of deprecated APIs might include references to the deprecation warnings of `forRemoval=true` and `forRemoval=false`. The `forRemoval=true` text indicates that a deprecated API might be removed from the next major release. The `forRemoval=false` text indicates that a deprecated API is not expected to be removed from the next major release but might be removed in some later release.

The descriptions below also identify potential compatibility issues that you might encounter when migrating to JDK 15. See [CSRs Approved for JDK 15](https://bugs.openjdk.java.net/issues/?filter=37957) for the list of CSRs closed in JDK 15.
