Just today, Nintendo 3DS firmware 11.4.0-37 has been released. I saw no other posts on this so far, so I am posting it. Here is what I found so far has been either temporarily or permanently broken/patched. BootNTR Selector: Working with latest version (2.7.3) UDSploit: Patched Soundhax: Patched (Finally Nintendo... Lmao) Safehax: Doesn't work without UDSploit, so therefore broken. 11.4.0-37 fixes the slowdown bug for some games like OOT3D that 11.3.0-36 has introduced. Confirmed by @Feffe Please let me know if anything else got patched. Yes, of course, if you have A9LH+Luma3DS, you can safely update.
