Write migration tutorial
On my development machine I installed dfply version 0.2.4. Now I installed dfply with pip install dfply on the server and suddenly I got NameError: name 'groupby' is not defined. It took me ages to realise it's not that code that is wrong, but you had a new release (which was such a surprise because it had been a while). It seems that your groupby is now group_by... maybe you can write a migration tutorial? Tensorflow did it reasonably well.
Yes I changed the grouby to be group_by to mirror the dplyr function. Apologies for the code-breaking change. One way to resolve this in your code is to have an from dfply.group import group_by as groupby.
Given that is the only function name that changed between v2 and v3 (as far as I recall) a migration tutorial wouldn't have anything in it except that, but I will add something at the top of the readme to notify people.
Thank you very much!
Also thank you very much for continuing development! It it much appreciated.
The code examples in the README.md are still on groupby - once again I got confused when reading the examples... ;-)
