WordPress 3.4 was just released and as always you should upgrade, if for nothing else, just to ensure you have the security fixes. As for functionality improvements, there is nothing really exciting about this release. You can preview theme changes before publishing them and change the size of the header in the default theme now–although you are still stuck with the massive amount of wasted space above the header unless you make code changes like demonstrated here. You can also create nice looking Twitter embeds by pasting the tweet permalink on a line in the editor–been doing that for a while now with the Blackbird Pie plugin.
If you don’t currently have your WordPress blog configured to render on mobile devi ces, then watch this video for directions on using the WPTouch plugin. In only a few minutes you have configure your blog to render very nicely on a variety of smartphones.
In a default install of WordPress, each time you edit a post or page, WordPress will automatically save your previous posts/pages allowing the possibility of reverting to a previous version of that post or page. This is a cool feature, but it can get a little ridiculous when you have dozens of previous versions sitting below the post–and taking up space in your db. As you can see in the following screenshot, with just a couple of edits to this post, I’ve already racked-up 4 revisions…by the time I finish editing, I’ll probably have a dozen or so…
