Here's a list of changes in my cut:

Reduced chat between C-3P0 and Bib Fortuna

Less laughter from Salacious Crumb

Gave Jabba new dialogue throughout

Took out the Jedi Rocks musical number

Took out beat where Boushh threatens Jabba with thermal detonator (example of contrived drama)

Took out horrible beat where Lando very slowly and deliberately reveals his face from under the mask

Took out Rancor scene (another pointless scene, designed to create contrived drama)

Took out the poor exchange between Luke and Han. They're about to be executed - why are they cracking (bad) jokes?

Took out Boba Fett from Sarlaac scene. In my cut he stays behind at the palace and chats up one of the dancers.

Took out Ben's lines about 'from a certain point of view'

Took out Lando's cheesy grin after Han describes him as the respectable one

Took out Han's 'good luck, you're gonna need it'

Took out 3P0's line 'exciting is hardly the word I would choose'

Took out entire scene between Lando and Han in the ship's hangar.

Took out Han worrying about the Falcon.

Removed Han's line about flying casual

Removed Han's line 'Hey, it's me!' (man, I hadn't realised how much of Han's dialogue is gone in this cut)

No longer does Han walk on the twig and the stormtrooper turns round. It always bothered me that Chewie growls a moment earlier. So I made his growl loud enough that the stormtrooper hears, turns, and sees Han.

Made several small cuts to the speeder bike chase

After Luke lightsabers the speeder bike and it crashes into the tree it no longer makes that annoying, comic, out-of-control sound

Whole scene between Leia and Wicket has gone

Han's line 'I hope she's all right' has gone. It's too on the nose.

Small cuts to the gang's first scene with the Ewoks, fewer Ewok shots and Han's 'proper?' also taken out

Several cuts during the scene where they're going to be cooked for dinner. As much cutesey Ewok stuff as posible edited out

The beat outside after Luke has explained their lineage to Leia, between Han and Leia now plays out in near silence: He asks her what's up, she looks sad then says hold me.

When that Ewok (Paploo, or whoever) takes the speeder bike, he zooms away and that's it

When the Rebel fleet appear and 'it's a trap' the ships fly towards the Empire's fleet... it cuts to Luke watching the battle begin.

During the Ewok battle there are many cuts - all the silly Ewok traps and machines are gone.

The awful call-back to Empire, where Han says I love you, Leia says I know, has been replaced by tense music

When Luke is hiding from Vader I made the image slightly darker to make his hiding more plausible. It's always bothered me.

Took out the humongous exploding shield generator. It seems to wipe out half the forest.

Took out Lando 'Yeehaaa' or whatever cheesy line it is, when they escape the Death Star.

Then the ending, huge changes:

I used the funeral pyre music from the SE soundtrack instead, it's longer and enables me to add a montage of key moments in Luke's adventure while he watches Vader's suit burn.

I used two tracks from the Battlestar Galactica soundtrack for the end celebration: Reuniting The Fleet and Wander my Friends

Taken out nearly all Ewok silliness from end celebration

Added Sebastian Shaw's ghost (sadly with horrible GOUT quality image)

Due to slower tempo music instead of the classic Star Wars quick transition to credits I freeze frame the last image and do a slow fade
