The 3.x series is expected to undergo continuing development for some time,

+# compatibility breaking changes
+
+Probably incomplete list:
+
+* Drop old `--getctime` option.
+* Remove compatibility code in `loadindex` to handle old index data layouts.
+* Make pagespecs match relative by default? (see [[discussion]])
+* Flip wikilinks? (see [[todo/link_plugin_perhaps_too_general?]] and [[todo/do_not_make_links_backwards]])
+* Enable tagbase by default (so that tag autocreation will work by default).
+ Note that this is already done for wikis created by `auto-blog.setup`.
+* [[tips/html5]] on by default (some day..)
+* Remove support for old `.ikiwiki/comments_pending` and for
+ pending comments located in the srcdir, rather than transient underlay,
+ from comment plugin. That support makes comment moderation slow as
+ it has to check all the old locations.
+
+In general, we try to use [[ikiwiki-transition]] or forced rebuilds on
+upgrade to deal with changes that break compatability. Some things that
+can't help with.
+
# future goals
-* Conversion support for existing other wikis.
- (Being worked on for MoinMoin and TWiki by [[Josh_Triplett|JoshTriplett]]
- and Jamey Sharp; support for other wikis should fit into the same
- framework.)
+* Conversion support for existing other wikis. See [[convert]].
* [[TODO]], [[bugs]], ...
-* Writing <a href="http://www.besttermpaper.com">research papers</a> for documentation purposes.
