On the Wordpress Codex for Wordpress 2.7, you will see a list of new features that Wordpress is planning to release for it’s next upcoming version of 2.7. When that release is I don’t know. But I do have here a list of what we could be seeing from the new version:

  1. Comments API
  2. Keyboard shortcuts for comment moderation
  3. Remove old/unused code
  4. Theme update api, like we do for plugins
  5. Some default shortcodes, maybe the most popular 10 from WordPress.com
  6. Dashboard and write box rearranging
  7. One-click plugin installs
  8. oEmbed support, tied in with shortcodes
  9. Admin-only reply thing, for admin replies to comments (7435)
  10. Better UI for post revisions, maybe an optional field to say what changed in a version
  11. Core updating
  12. oAuth support
  13. A frame-like method for moderating ping/trackbacks
  14. GeoData for posts, comments, attachments, etc.
  15. Duplicate post Tags UI for other taxonomies (6387)
  16. SWFUploader make it work with Flash 10
  17. Template tags to do everything the custom gallery on ma.tt does
  18. Plugin browser embedded
  19. Codepress code highlighting for template editing
  20. Php xref hosted on WordPress.org
  21. Tag intersections, all posts that have tag x AND y (We already do this)
  22. Menu editor
  23. Separate Large and Full image sizes, related improvements (7151)
  24. Unbalanced tags across more and nextpage tags
  25. Sitemaps by default
  26. Comment threading
  27. Batch editing of posts
  28. Refresh of the importers
  29. Subscribe To Comments plugin in core?
  30. MPTT for hierarchies
  31. Gallery post_type
  32. Versioning of template edits
  33. Documentation links for functions used in currently edited template

This is not an official list of new features coming. But it is some that are being tossed around the drawing board. The ones in bold I would say would be very cool if they could have those ready for 2.7. And as for #3, I would have to say that even though this sounds general you cannot overlook the importance of that type of work to an open source project. By continuing to go back and clean out old code, the project only gets better and better. It’s good to know that Wordpress is constantly trying to make their CMS better and cleaner code wise at the same time.
