Here are steps required to migrate to certain versions:
1.x -> 2.x¶
To migrate from v1, you will need to change all divider calls from:
area4.dividerX # or area4.divX()
X is the divider number, to:
2.x -> 3.x¶
This version removed the duplicate divider (was #201), so all the dividers with numbers/IDs BIGGER than 201 need to be shifted down by 1, so if you are using any of those dividers, you will need to change the number. For example:
area4.divider(208) # needs to be changed to: area4.divider(207) # however, anything BELOW 201 does NOT need to be changed!
