I'd suggest to organize an update of the ancient 2006-state dokuwiki plugin (the issue text editor), including the part of dokuwiki's media manager that's mandatory to upload images.
However, I'm reluctant after having read that v1.0 is freezing because of work underway to get to v2.0.
Please indicate whether it makes sense to prepare to a plugin update soon, or if it makes more sense to wait. Or... if the v2.0-route already includes an update of this plugin.
