Long time no message!
Anywho, I've been working today with RDKit 2015.03.01 and in the process of
generating a grid of molecule depictions (Draw.MolsToGridImage()), I
received the error message below.
>From the last line, it seems there has been an API change that changes
tostring() to tobytes(). I also found that fromstring() needs to change to
frombytes().
When I made these changes and saved the results, everything works fine. I
thought it might be useful to know given the upcoming release.
