I've considered it, just not found and taken time to do it.
I'm sure the rest of the team probably has had even less time.
We'd love more folks to use intelligence in the mean time; read the release date of the original post, read the last few posts of a release to see if anything has been updated, THEN decide to try it or not and realizing that if it's not newer than October 2012, then it's a good chance it won't work.
If someone would at least like to make a single post in response to this topic where they link to the first page of all releases that have been updated, by us or otherwise, to work in GM13, that would be swell (and serve as a temporary location for us to point folks 'here's what we know works right now' until we find time to come and do the moves.
What it might look like
Code used to make above.
