Get it, while it's hot :)
There are way too many changes since the 1.2 release. New admin design, more blog features and many others, we lost track, as well...
See also this post for some info about switching the branch.
We plan to release more often in the future, with the new subversion layout it should be easier. The immediate plans for the 1.4 release aren't that big and could be not that far off.
The 1_3 branch will now only get bugfixes, new features go only in trunk. It's at the moment quite safe to use trunk, as we use this for projects we're currently working in. That's also the reason, why there almost certainly will be a 1.4 release soon.
The amount of trackback spam we get is amazing. It's all (or most of) rejected due to our spam filters, but it's still unnecessary (Most of you won't detect it anyway, as we don't send rejected comment notification mails by default). To at least cut down that a little bit, we added a new global option (goes into conf/config.xml): "blogTrackbacksTimeLimit". If that is set to true (it is by default), trackbacks are disabled after one month. I think, that in very few cases one has to trackback a post, which is more than a month old (very few people trackback at all anyway). And if you leave the comments open, that person can still do a "Manual Trackback" then.
I put this into the 1.3 branch as well, as it shouldn't break anything (but as usual, you should delete the tmp/dir after an update).
If you have a customized theme, you have to adjust blog.xsl, so that it doesn't display the trackback url anymore, if trackbacks aren't allowed. See the diff for what has to be done. If you don't change it, trackbacks are still not accepted, just the text on the post itself is missleading :)
