@davidastephens ok I think this is ok to go. can you do the release? I can trigger conda-forge once the release commit is pushed.

I don't have access to readthedocs acct, can you add me.

Is there a conservative estimate on when 0.5.0 will be released as well as if the Yahoo Finance fix will be included? Thank you.

@jorisvandenbossche is the only owner for read the docs, but I could trigger the update.
