Feature projects are intended to explore potential ideas for WordPress core. Feature projects are similar to the previously used feature plugins in many ways (including in name), but may not take the form of a plugin; in fact, they likely do not begin as plugins. Most start as ideas that need exploration to be more fully formed/fleshed out before implementation. Others become discrete patches on tickets. Others may turn into multiple plugins, breaking out the successful parts of the project into patches for core, while iterating on the less-successful pieces. Still others may remain in plugin format even after reaching a polished point, as they may not make sense as a bundled part of core but serve a valuable purpose for users.

Projects listed below are not necessarily scheduled for a particular release, nor are they promised for any future version of WordPress. For more on feature plugins, see this post.
