After going through a full debug stage (and some lovely preview videos coming out on YouTube), WordPress 3.4 has been released .This release includes significant improvements to theme customization, custom headers, Twitter embeds, and image captions — here’s a short clip with the highlights:
The biggest change is the theme customizer which enables users to play with various looks and settings of current themes, or ones not active, without publishing the changes live. For themes that support it (we assume developers will take great advantage of this) you can change colours, backgrounds, headers, and apparently there is a lot more planned for it.
WordPress has also expanded their system to support embedded tweets. just put the Twitter permalink onto a new line in a post, and it will turn into a embedded Tweet like below:
And finally image captions have been improved to allow HTML, like links, in them.
There are hundreds of under-the-hood improvements in this release, notably in the XML-RPC, themes, and custom header APIs, and significant performance improvements in WP_Query and the translation system. The Codex has a pretty good summary of the developer features.
So Dont forget to update, and for those of you who use our one click install system, you should have been notified by email of the updates.
