Is there any way for a game creator to send a notice to people who had bought their game that a new version has been uploaded?

This seems like it could be a useful ability.

You can use the email tool to send an email to everyone who has bought your game: http://blog.itch.io/post/74954872362/you-can-now-e...

Additionally, we do send a notification event when files have been updated to all buyers.

Huh. When House of Many Doors was updated a few hours ago, I didn't get a notification. Thye email tool thing is useful, though. I'll be sure to let Mr. Tuffs know it exists. Thanks!
