Cosmo is the OSAF calendar sharing server. With your favorite calendar program (Chandler, Apple iCal, Mozilla Sunbird, or any other WebDAV or CalDAV enabled client), you can share your calendar with other people by publishing it to Cosmo. Your shared calendars can be subscribed to and updated by anyone, even if they don't have an account on your server. Cosmo provides Atom feeds for shared calendars, so you can track updates in your favorite feed reader and integrate your calendar into your Web site or blog.


This release includes a major security fix as well as a small amount of minor bugfixes. The focus for this release was to fix the security hole present in prior versions that allowed users to gain write access to items without a read-write ticket. Part of this fix required changes to the desktop client, so upgrading the server to 0.13.0 will require upgrading Chandler Desktop to 0.7.5 in order to support certain features (sharing items in multiple collections).
