Liege is moved 1 hex, Antwerp is moved to a more accurate position. The Schelde river is altered too. Forests and clear hexes are altered to simulate the real terrain better. The Albert canal is added.
Because of these changes a quick conquest of Belgium can be slightly more challenging if you do a blitzkrieg. This is mainly due to the Albert Canal. If you do a sitzkrieg the changes make the invasion easier since there are more clear hexes around Brussels. So you can strike deeper into France of the first turn of Case Yellow with your panzers.
Because of the changes we have made minor changes to the OOB. E. g. one German mech in the east has swapped position with a garrison so the mech can be railed to the west on turn 1. One Dutch garrison is moved to 1x SE of Hague. This garrison is holding the Grebbe line (too weak to have any impact in this game). That means the garrison can more easily be destroyed since it's not protected by a river.
Another change is that the Allied morale loss when Brussels falls is altered so you get some morale loss if Brussels falls in 2 turns instead of 1 turn. The 1 turn loss will give the Allies a 20 morale loss. The 2 turn loss will give the Allies a 10 morale loss (half the value). So if you do a blitzkrieg and the dice are against you then you can still salvage something by taking Brussels the next turn.
Here is my Blitzkrieg turn 2 attack that takes Brussels almost every time.
Turn 1: Transfer 2 corps, 1 mech, 1 armor and entire Luftwaffe from the east.
Turn 2:

This image shows the start location of the units at turn 2. The key is to get the 2 garrison units into fighting.
1. Move the garrison 2xSE of Arnhem to 1xNE of Arnhem and attack garrison in Arnhem.
2. Move corps 1x NW of Essen to 1x N of Arnhem and attack and attack garrison in Arnhem. Advance after combat.

This is the situation after the first 2 attacks.
3. Move the garrison 1xN of Scholven to 1xN of Arnhem and attack garrison 1xSE of Hague.
4. The unit will often retreat to 1x S of Hague. Send strategic bomber to the garrison and finish it off with a bombardment.

This is the situation after the Dutch units are dealt with. Hague is left for now. It can be dealt with in turn 3-4.
5. Use fighter 1xNW of Frankfurt to bombard Belgian garrison 1x NE of Brussels. This attack serves 2 purposes. One is
to engage the French fighter and the other is to deplete and drop efficiency on the garrison. This attack must happen
first so the English fighter can't engage.
6. Use fighter 1xSE of Cologne against Belgian corps in Brussels. This will engage the British fighter and maybe inflict
a step loss upon the Belgian corps.
7. Use tactical bomber 1xNE of Cologne to bombard the Antwerp garrison.
8. Use the tactical bomber 1xS + 1xSE of Cologne to bombard Brussels. Expect 1-2 step losses on the Brussels corps.

This is the situationa after all the airstrikes.
9. Use corps 1xNW of Scholven to 1x NE of Antwerp to attack the Antwerp garrison . Do NOT advance after combat.
10. Use corps in Cologne to move to Antwerp and attack garrison 1xS of Antwerp. Do NOT advance after combat.
Remnant of garrison will almost always retreat 1xS.
11. Use corps 1xS of Cologne to 1xS of Liege and attack Belgian garrison 1x SE of Brussels. Advance after combat.

This is the situation when Brussels is stripped of its defenders.
12. Move the German mech unit 2xN of Cologne to 1xNE of Brussels and attack Brussels. Expected Brussels losses is 3 steps.
13. Move the German armor unit 1xN of Cologne to 1xNW of Brussels and attack Brussels. Expected Brussels losses is 2 steps.
Advance after combat to force a Belgian surrender.

This is the situation when Belgium surrenders. Notice that the 2 airstrikes on Brussels will usually inflict 2-3 steps. The
armor and mech attacks will inflict usually 5 steps, sometimes more. You only need a total of 7 hits to take Brussels.
I tried this about 10 times and failed only once. Then Brussels remained with 1 step. You fail usually if the airstrikes
fail to do any damage. That happens rarely.
Sometimes you get better than normal results so you don't need the strategic bomber to attack the Dutch garrison.
Then it can be used against the Belgian garrison 1xNE of Brussels. Then you get another fighter against Antwerp
or you can accept bomber losses and use both fighters against Antwerp and both bombers against Brussels.
