## 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

This instruction records that the results are now initialized
and should be scanned during stack movement and garbage collection.
It is typically easier to arrange that assembly functions do not
return pointers or do not contain call instructions;
no assembly functions in the standard library use
<code>GO_RESULTS_INITIALIZED</code>.
