I've pushed out a small, new version of Dojo Offline. Release notes:

* An optional new feature has been added to speed up the sync process. Currently, we always refresh the list of offline files during syncing; this can be quite slow if you have alot of files, however, and I have added a way to version your offline files. This means that we only refresh offline files when the version changes, which can speed up syncing considerably. More details here.
* There used to be a bug where if you were running multiple Dojo Offline-enabled applications from the same host that some of their data or files could collide -- we now internally namespace our offline file and data cache so this will never happen.
* A number of fixes have been made to syncing in general to make it more robust.

The developer bookmarklets that help you clear the Google Gears cache have changed; you should delete your old ones and get the new ones here.
