starting from the top left grid, the left black square rotates by +2 positions, while the right one rotates by -1 position. The answer is the missing positions in the given list of grids.

Rule 2 => the right col. has 2W & 1B above the line, so the missing group must have 1B & no W above the line

Rule 3 => the right col. has 1B & 1W below the line, so the missing group must have 2B & 2W below the line

Rule application to the right column:

Rule 1 => the right col. has 2B & 3W so the missing group must have 3B and 2W

Reasoning:
Let's consider the 3 groups on the left column.

1st rule:
There are 5B and 5W

2nd rule:
There are 2B above the lines
There are 2W above the lines

3rd rule:
There are 3B below the lines
There are 3W below the lines

Top: 1B
Bottom: 2B & 2W

Interesting to see that:
- v1.2.0 (26.6%) & 0.9.1 (21.3%) are still the most downloaded
- versions related to #Uniswap V4 (v2.0.0 & its pre-releases) come third (18.7%)

=> the vast majority (81.3%) still concerns #Uniswap V2 & V3.

We'll see how this breakdown changes in time.
