It would be great, to publish some kind of Roadmap.

No one is working full time on DokuWiki (and we have lives, too) so it's hard to estimate when the next release will be ready. We usually do new release when some new features were added, all major known bugs were fixed and we think it is time to do a new release. We currently do that about every 6 to 9 months.

You can help to speed this up by joining the mailinglist and submitting bugfixes and implementing missing features.

If you are eager to try a newer version before it is released, fetch it from the Git repository or download one of the daily snapshots.
