-## Overview
-
-The start of release changes, the changes that turn JDK _N_ into JDK
-(_N_+1), are primarily small updates to various files along with new files to
-store symbol information to allow `javac --release N ...` to run on
-JDK (_N_+1).
-
-The updates include changes to files holding meta-data about the
-release, files under the `src` directory for API and tooling updates,
-and incidental updates under the `test` directory.
-
-## Details and file updates
-
-As a matter of policy, there are a number of semantically distinct
-concepts which get incremented separately at the start of a new
-release:
-
-* Feature value of `Runtime.version()`
-* Highest source version modeled by `javax.lang.model.SourceVersion`
-* Highest class file format major version recognized by the platform
-* Highest `-source`/`-target`/`--release` argument recognized by
-  `javac` and related tools
-
-The expected file updates are listed below. Additional files may need
-to be updated for a particular release.
-
-### Meta-data files
-
-* `jcheck/conf`: update meta-data used by `jcheck` and the Skara tooling
-* `make/conf/version-numbers.conf`: update to meta-data used in the build
-
-### `src` files

-  for the new version
-* `src/java.base/share/classes/java/lang/classfile/ClassFile.java`:
-  add a constant for the new class file format version
-* `src/java.base/share/classes/java/lang/reflect/ClassFileFormatVersion.java`:
-   add an `enum` constant for the new class file format version
-* `src/java.compiler/share/classes/javax/lang/model/SourceVersion.java`:
