Aaron Giles, the creator of the emulator and a former LucasArts employee himself, announced the arrival of the new update on Twitter earlier this week, and it looks like he's been extremely busy behind the scenes as there are a lot of great new additions and features included within.
This includes support for all remaining DOS-based Lucasfilm/LucasArts games, support for commercial add-on packs, and the ability to add a CRT simulation filter to your game of choice.
As Giles notes in the documentation, the front end for the emulator has also undergone a bit of a dramatic transformation as part of the new update as well.
It now displays much higher resolution graphics and some light animations, and features various quality-of-life improvements, allowing for multi-disk installation (for example), as well as an expanded set of configuration options for setting the CPU speed and remapping your joystick controls.
