 * Re: The 'Send me HTML emails' preference will be phased out. While the existing choice will be honoured for existing emails, it will default to 'on' for all new-style emails. All HTML emails include a plain text version, which will continue to be accessible via your email client settings if desired.

Just an FYI: the reason I chose to disable that option, despite my email client being set to only show text/plain anyway, is because the text/html portion of the email is quite large in comparison.

For instance, I received the notification email about the "new sharing options" for two different accounts, one with HTML emails enabled, and one with it disabled. That's quite a large comparative difference, and while it doesn't matter much for a single email, bytes have a tendacy of adding up.
 * text/plain: 748 bytes
 * text/plain + text/html: 17,081 bytes

Thanks for honouring the existing setting, I hope this explanation gives you some insight.

And thanks for putting in all that extra work to support text/plain emails.
