Off the top of my head here are some of the larger changes;
- new crawl (leaving destination of map to unfold during the film).
- Finn is just his name, Poe doesn’t name him.
- Redubbed and subtitled Unkar.
- Moved and recoloured TIE Apocalypse Now shot.
- No Phasma (glimpsed once during the big Hux speech I believe, otherwise she’s gone).
- Heavily reworked rathtar sequence (no Scot or Kanjiklub, or rathtars!) with new subtitles.
- Moved and rejoined sequences.
- New music in Maz’s castle.
- Shouting “Traitor” is left for Kylo at end, trooper here majorly edited.
- Moved some Snoke scenes around.
- Starkiller firing moved to end (as others have done here also).
- Composited in some captured Battlefront footage of a Star Destroyer with TIES over Takadona.
- Kylo searches Falcon reinserted.
- Muted/re-cut a lot of 3PO.
- Un-mirrored some shots.
- Restructured shield down sequence by moving some scenes and incorporating some TFA ad footage.
- R2 unveiled near close.
- Dialogue and pacing cuts (lots and lots of these actually - some tiny).
- Rescored end with trailer music (epicness).
- More I am probably forgetting…
