## For developers

Release notes should be added to `next` by editing existing files or creating
new files. **Do not add RELNOTE=yes comments in CLs.** Instead, add a file to
the CL (or ask the author to do so).

At the end of the development cycle, the files will be merged by being
concatenated in sorted order by pathname. Files in the directory matching the
glob "*stdlib/*minor" are treated specially. They should be in subdirectories

     * For example, for the Java language, the pattern includes all files with the {@code .java} suffix.</p>
     *
     * @see java.nio.file.FileSystem#getPathMatcher(String)
