Version 1.0.2 is now available for download from Sourceforge. This is only a bugfix release, and contains no new features.
Here’s the Changelog.
About the upcoming plugin architecture:
From Matt:
WordPress is moving toward a more robust plugin system that will make distributing and installing plugins or hacks easier than ever. In 1.2 there will be a new folder called
wp-content/plugins. To install a plugin you simply drop the file the plugin-writer provides into that folder. You then go to the “Plugins” section of your administration and activate that particular plugin. You may or may not need to modify your template to take advantage of the new plugin; the author will provide instructions for that.
More on plugins from a developer perspective later.
