Then read the developer's labeling.

"Stable releases do not change except for bugfixes and for
portability fixes. New features are tested out in experimental
releases"

"New features are tested in experimental releases. They become
part of the next official release once the code has not
changed for a significant amount of time. Although this code
is still subject to change, it runs on all of Wietse's systems
so it is production quality."
