It's always been like that. Not everyone codes the same. Not everyone has the same hacking goals. Plutoo and co dont really care for much else other than Homebrew. SciresM wants to crack open the switch. The latter has always said to stay on the lowest firmware possible (for obvious reasons) while the former suggested to update to 3.0 asap unless you were on 1.0.
Of course 1.0 has something the others don't - a different entryway that has been patched on later releases. Other than that it's identical (as far as I know) to the rest.
Thus SciresM is planning to release code for 1.0.0 but not (yet ?) for upper firmwares ?
Otherwise why advising people to stay on 1.0.0 ?
