.LRN 2.3.0 Alpha 2 has been released

The tarball is available here. An existing site using theme-selva should work fine after an upgrade. An existing site using the sloan theme or a variant will be missing the navigation breadcrumbs (this will be fixed for beta). To upgrade an existing site to the new Zen theme, install the theme-zen package, then visit theme-zen/admin while logged in as an administrator.
