and notices for code bugs or limitations.
The same text may be reused in identical form on multiple pages.
Use this section to cross-check the documentation changes for feature requests and
problem reports, and to see the details in the issue-tracking system for features
and fixes that are only mentioned briefly in the documentation, such as performance
improvements that do not require any user tuning actions.
