Right - you only have to write a line or two to support both ways in your code. > For MimeWriter there were (what looks like from a relatively casual > look) fairly big API changes as well - even if they were only name > changes (which is substantially similar to the requirements for moving > from optparse to argparse). True, but it's fairly easy writing a compatibility module which does what MimeWriter did in terms of the email package. I wonder why that wasn't added to the email package - I would certainly have complained, but I've never used MimeWriter myself and didn't notice the deprecation at the time. Here's an example of migrating from MimeWriter to the email package: http://thomas.apestaart.org/moap/trac/changeset/401/trunk/moap/util/mail.py Note that the MimeWriter module still exists in Python 2.7: """ This module is present only to maintain backward compatibility.
