Only one function was updated, the function which loads theme body-data with theme-shuffling enabled. This now does: if(loadedsize > input_max_size)fail. Hence, the latest exploit used by menuhax at the time of this sysupdate release is now fixed.
RomFS was not changed at all.
Old and New 3DS Internet Browser were updated. Both browserhax_fright_tx3g (New 3DS) and spider28hax (old 3DS) were fixed.
Minus changes from an older CTRSDK version(CTRSDK version seems to be the latest now), only one actual SOC-specific function(L_11154c) was updated. The previous version did: <write u8 0x0 to ptr and increase ptr by 1>. The current version removed this so that L_11f9f0() is called with ptr, without writing data to ptr+0/changing ptr.
Multiple titles for JPN-only were updated. For System Settings and "Nintendo 3DS Camera", only the manual content was updated(the main contentid in the TMD wasn't changed at all). Other titles were updated for JPN-only too, presumably with the same manual-only change.
