I think they generally try to get it out the week of a sets release, but sometimes editing takes longer than expected for example [Eldritch Moon's Update Bulletin] (magic.wizards.com/en/articles/archive/feature/…) didn't come out until 7/28 nearly a week after the set released
The SOI one it looks like came out the day before the sets release
@diego How would you even classify that ability into a template to match against?
You can't use "Starts with 'If'" because there are a lot of other abilities that use "If" but aren't replacement effects
Even if you explicitly exclude conditional alternate casting costs, like on Angelic Favor, you still have to deal with conditional attacking and blocking restrictions like on Ekundu Cyclops and conditional combat damage reassignment on Cunning Giant.
