    Hi Rob,

    I'm afraid not. The 2.7 version of atto is a completely different beast to the 2.6 version. We rewrote the API when we put it into Moodle core and I have no plans to write this plugin for the 2.6 version of the API.

    Best wishes,

    Has anyone tested this plugin with Moodle 2.8? We're currently testing the latest version of Moodle and would like to integrate this Atto plugin. Thanks.

    This doesn't seem to work on 2.9+.
    Is it posible to get a newer version which works on 2.9+

    This plugin looks fantastic. Is there any chance this will be updated to work in 2.9?

    The version working with Moodle 2.9 can be found at in the master branch. We've sent a pull-request to Andrew, how he'll merge it soon.
