In addition to the changes mentioned above, during our TPAC 2013 meeting, we also talked briefly about a version of Workers that does not include Shared Workers [Mins]. I'm not opposed to working on a new version of Workers but I think it would be helpful to get the group's consensus re the plans and expectations for the Dec 2012 [CR]. The interop data James gathered in [James] is certainly more promising than the interop data in [Wiki] but James data does not include IE. As such, it's not clear to me what level of interop we have now for the 4 main browsers, nor if we have sufficient commitments from implementers to eventually exit CR (and if so, our best guestimate on when we can expect to meet the CR exit criteria). -AB [Mins] <http://www.w3.org/2013/11/12-webapps-minutes.html#item08> [CR] <http://www.w3.org/TR/2012/CR-workers-20120501/> [Wiki] <https://www.w3.org/wiki/Webapps/Interop/WebWorkers> [James] <http://hoppipolla.co.uk/410/workers.html>
