This release includes a substantial number of core code improvements as well as an array of useful new features.
Some highlights of this version are:
- One click internal bbPress forum integration allowing you to set up group forums in less than a minute.
- A global forum directory (example) allowing you to easily browse public facing forum posts regardless of the group they are attached to.
- Completely re-written theme handling. One theme now controls all of your installation. No hidden HTML, everything is in the template ready for you to skin.
- Easily create themes that are upgraded automatically when BuddyPress is updated.
- Total site admin control of all content within an installation. Edit user’s profiles, update avatars, mark users as spammers, manage all groups, delete site activity entries.
- Activity streams everywhere. Activity streams can be filtered allowing for feature specific activity streams or adding an activity stream to your custom plugin.
- A new status updates feature is included in BuddyPress 1.1. Actions and filters are included to allow plugin developers to hook into any external service.
An awesome group extension API allowing developers to easily extend groups and add completely new features.
Además de los grandes cambios referentes a los activity streams, lo importante para los desarrolladores que no lleguen de nuevas a BuddyPress es que la estructura de los temas ha cambiado. Y Andy nos ha preparado un tutorial de cómo migrar nuestro tema de 1.0.x a 1.1.
