So I can't comment on my run because my account isn't 7 days old yet, or send a message so im reaching out here. My 9:09 is on patch 1.8a because it was technically yesterday, I just got around to posting it today. The 1.8b just came out today.
I'm not sure how often these little patches are going to be so it might not be prudent to make a new set of categories for every patch but at the same time each patch also changes things slightly allowing for different possible run times.
I'm not sure the complete capabilities of customization for the page. But I figure maybe the best way to do it is split it up between mega death and normal death. Then split again between past versions and current version.
So essentially you'd have 4 pages, past versions death/mega death and current versions death/megadeath. Then on the past versions page you could have some sort of indicator on exactly what version the run is on.
At some point in the run I think the players should have to pause because it shows the version the game is on in the pause menu.
I think its also good to run doppelganger on days when he is copying the sorcerer. I just got a 9:39:02 on that. The extra soul heart every floor adds up if you have the perk which gives you extra damage per soul heart
