The improvements include the new file sharing in eyeHome: With two tabs (Private files and Public diretory), users can manage their private files and copy files easily to the public directory, where all users in that system will be able to see and manage them.
The 0.9.1 version also includes a very important core update, the new user directory structure. The accounts directory has been moved to a new organization system, supporting over 400 milion users. Upgrading is also simple, and the users are moved "on the fly" to the new structure when they log in into the system.
All the external applications should work correctly, but we recommend to update two apps when upgrading to 0.9.1: Maps.eyeapp and eyeAmp.eyeapp, because the ancient versions used a non-official way of handling directories, and could cause problems with the new structure.
Finally, this release also fixes two XSS security bugs, so we recommend all users to upgrade to this new version ir order to have the best security. This two bugs were discovered by Jose Carlos Norte, who is a new eyeOS developer.
The new version can be downloaded from the Downloads page. Thanks!
