Changes between Version 5 and Version 6 of Ticket #4895

v5	v6
1	1	As was done for categories in #4750, let's add private tag!__in, tag!__and, and tag!__not_in query vars.
2	2
3		Let's also decide on how to specify intersections and unions in the public query vars. We have tag_id and tag. tag_id currently takes a single numeric ID, and tag takes a single tag slug. tag is the var we use when creating links and such. tag_is isn't exposed anywhere at the moment. I think we can extend tag to allow the use of "+" to request tag intersections and commas to request unions. Only one or the other can be specified in the same request.
