Today I released a new major version of premailer where the only difference is that one of the default options have changed from
The git commit for this change might look big but the only difference is that now, by default, the HTML
class attribute is kept in the output HTML.
premailer started, the land of HTML emails was very different. Basically, you used to not use CSS media queries, so, no reason to keep the
class attribute. Now, these days, all pretty HTML emails need media queries and for that to work you need to have the
class attribute kept in the HTML.
So fear not the major version upgrade! If you used to use
premailer like this:
from premailer import Premailer transformer = Premailer(html) output_html = transformer.transform()
You now need to change it to:
from premailer import Premailer transformer = Premailer(html, remove_classes=True) output_html = transformer.transform()
As always, you can play with it on premailer.io.
