Luma3DS is a program to patch the system software of (New) Nintendo (2)3DS handheld consoles "on the fly", adding features such as per-game language settings, debugging capabilities for developers, and removing restrictions enforced by Nintendo such as the region lock.
What's New:
*Hide the "Force routing audio output to headphones" option from bootmenu, and extend it to force-route audio to speakers too
*Fix handling of negative "brightness" values in screen filters advanced options
*Clarify in bootmenu that the "autoboot homebrew" option is meant to launch the Homebrew Menu
*Always crash when processes unexpectedly fail to load, to help troubleshooting
*For sysmodules, code.bin and exheader.bin loading are now deprecated. CXI file loading should be used for those (see 12.0 release notes), and future release will make CXI loading more seamless
