• jQuery 1.6.4 and jQuery UI 1.8.16. And that’s the full UI including widgets and effects. This will make it a lot easier and simpler for plugins using UI components that are not used in core as they will be able to just enqueue whatever they need.
  Note: there is a known bug/regression in UI Draggable since version 1.8.13. When connecting a draggable item to a sortable container, the HTML ID of the item is removed, #17952.
• WordPress Editor API. This is an updated API for both TinyMCE and Quicktags that outputs all parts of both editors in the same way as used on the Add / Edit Post screens, #17144. Plugins will be able to use the WordPress editor anywhere including the Visual/HTML tabs and the links to upload files and show the media library.
• Quicktags refactoring. This was necessary in order to make it fully multi-instance compatible, #16695.
  Note: if your plugin adds a Quicktags button please enhance it to use the new methods in quicktags.js.
• New multi-file uploader. Plupload was included as a result of Google Summer of Code project, #18206. It’s more stable and has a lot more features as well as chooses the best available interface that the current browser supports: HTML 5, Silverlight or Flash.
  Note: two actions that were specific to SWFUpload were renamed and there is a new filter ‘plupload_init’ that gives access to all initialization options.
• Other enhancements: wp_enqueue_script() now works mid-page and prints the late enqueued scripts in the footer #9346, wp_localize_script() uses json_encode to properly escape and output all strings, #11520.

First, on the extend plugin directory, you may notice some new pie chart fun on the stats tab for each plugin. This shows a percentage breakdown of the versions being actively used by that plugin’s users. Only slices greater than 1.0% are shown.

Secondly, since data kept in a box is not very useful, there’s a new API for getting this data. Usage is fairly obvious from just a simple example, which gets the version breakdown of one of my own plugins:

http://api.wordpress.org/stats/plugin/1.0/simple-facebook-connect?callback=demo

The callback parameter is optional, of course, and provided for people who want JSONP usage.

Note that the version data is relatively new, so we don’t have it for all plugins at present. It will get better as reporting continues. For those interested, it’s saving the total counts of the version numbers as reported by the plugin update-checks over the last week. Since the data at present is only from one day, it’s not very accurate.

http://api.wordpress.org/stats/wordpress/1.0/

http://api.wordpress.org/stats/php/1.0/

http://api.wordpress.org/stats/mysql/1.0/

A few notes about these numbers. First, they are summary percentages for the previous day (where day is based on GMT). You’ll also notice that these numbers don’t really line up with each other, this is because the system normalizes the version numbers and throws out odd/invalid versions (I was surprised by how many odd version strings there are out there). As a result each category is best compared to itself, instead of trying to compare PHP with MySQL numbers.

The content type returned for this data is ‘application/json’, your browser may or may not display them correctly.

This is a start, there are more things to be added to this in the future. One obvious item is support for getting numbers for previous days and date ranges. Another would be to add some pretty graphs to WPORG to display this data.

attribute_escape() is now esc_attr()

Additionally, you can do attribute escaping and translation in one go. Just add the translation function to the end. Like so:

• esc_attr__() — translate and return, attribute-escaped.
• esc_attr_e() — translate and echo, attribute-escaped.

Will be following up with esc_html (with __() and _e() variants), esc_url(), maybe some more. Will be nice, short, predictable, and allow you do translate/escape in one go without a lot of nested parenthesis.
