This update was based on the originally released version, not the Plus version, as it was often cited as the better one.
However, the update aims to combine the best of either version.
The update was designed for the next version of the megapack coming January 2023: https://sm64romhacks.com/megapack/
One major aspect in the changes made was about redesigning the red coin missions so that they would be a bit less about going literally everywhere in a level.
The most essential changes are the following:

V2.0 (made by FrostyZako):
- The Secret Aquarium renamed to The End
- Reduced red coins in cap stages from 8 to 6
- Made star replicas regular, permanent stars and relocated two of them
- Fixed the broken warp on overworld 2
- Made the WC entry more obvious
- Lowered final star count requirement from 53 to 30 stars
- Overhauled dialogue
- Applied patches: Newest parallel camera, no false ledgegrabs, no lives, elevator patch, shells respawn, cap timer, slope fix, exit course while moving, hoot tweak, nicer looking HUD, red coins display properly, 46° wallkick
- Moved red coins in cap stages
- Moved each a red in C2, C3, C4 and C5
- C1: Moved all reds to the lower level part and added plenty of coins
- C2: Added an invisible 10 coin box in an obvious position as a gimmick
- C3: Replaced jumping box at MC entrance with hidden boxes
- C4: Added a blue coin switch where the moved red was
- C6: Redesigned the red coin mission, added lots of coins to the now otherwise useless level section
- C7: Added coins, renamed "Fly Around" to "The Owl's Invitation"
