Chagnes: The 3D rendering engine is now almost twice as fast as in v2.6, parts due to using MMX code, parts due to general optimizations. Most games aren't running that much faster, though the improvement may be significant in games that have high rendering load combined with little cpu load. The new Auto Backup detection does detect the correct type when starting the game, and (theoretically) it should properly save data later on in the game (though without at least a gigahertz computer, it'd be a pain to verify that).
(faster 3d rendering, backup detect, rtc-irq, better texture interpolation,) (perfectly accurate edge-marking, translucent-poly-id, shadow-poly support,) (capture in vram display mode, debug gui/warnings, cpu/ipc/div/sqrt details) -

nds/debug: allows nintendo to write more serious nonsense to (R) baseband regs - nds/timings: re-fixed arm7/arm9 sync (new arm9-66MHz timings vs arm7-33MHz) - nds/video: supports capture from 2d/3d engine in vram display mode (nanostray) -
