v3.0.0

objdiff v3 is a ground-up rewrite of many core systems, with added support for new architectures (SuperH, PPC64 with AltiVec and VMX128, and x86_64). This release brings sweeping improvements to performance and extensive new features.

objdiff's redesigned WebAssembly API now powers objdiff-web, available as a Visual Studio Code extension and as an experimental view in decomp.me.

Many thanks to all who contributed to v3:

• @LagoLunatic
• @SquareMan
• @sozud
• @AetiasHax
• @AngheloAlf
• @anpage
• @r-burns
• @stravant
• @ethteck
• @rjkiv
• @CelestialAmber
