UPDATE: we regularly push updates to the developer plugin, make sure you grab the latest version here: https://github.com/Automattic/developer.
We’ve pushed out v1.1 of the Developer plugin, which is packed full of goodies for WordPress theme developers.
You can now indicate that you’re working on a theme for a self-hosted WordPress install to get recommendations on a number of must-have plugins as suggested by the WordPress.com Theme Team.
We also cleaned up a few things, fixed some bugs, added some new plugins (User Switching by John Blackbourn and Pig Latin by Nikolay Bachiyski) and some other useful resources (like the _s starter theme).
(Note: we also pushed out v1.1.1 shortly after to fix an issue with the plugin slug for the Pig Latin plugin. Thanks bobbingwide for the fix.)
As always, if you’d like to check out the code and contribute, join us on Github; pull requests, bug reports, and plugin recommendations are more than welcome.
