The GTAC engineers reviewed a lot of articles last week on Tuesday and as a result we published a very big list of articles! This is the largest group we have published so far in a week since after the launch of the GTAC KB. We are looking into grouping this list of new articles by product/software in the future, so that the list is more useful. Please let us know if you think this will be a useful feature.
