Everyone needs to calm down.
What we know for a fact so far, either by Smealum or other GBATemp forum users:
- Ironhax is dead, at least for now
- Browserhax and Menuhax should still work on o3ds if you update payloads
- rxTools and ReiNAND both seem to properly update emuNAND to 10.4
- If you update your emuNAND, it won't affect your cold boot into rxTools from sysNAND, if your NANDs aren't linked (seriously this is obvious, and you should always have your NANDs unlinked anyway)
Yet to be either confirmed or denied:
- Kernel exploit patches
- The status of what games will require updates, and what don't (if they don't all require it)
- Browserhax may not work on n3ds
If you find anything else or can confirm or deny any claims, let me know.
