sell extension on marketplace

[yonghan]

hi admins,first of all i would like to apologize if i post in the wrong board.I would like to ask about selling extension on marketplace.here is my question :

1.Are there any notice given to the purchaser if the extension has updates and they need to update it?
2.if there no notice,is it possible to send email notification manually to inform the purchasers that there are new updates.

Thanks a lot.

Currently there is no notice of update. This is considered for near future.

I believe there is a notice sent if new version is added to the product. 
We will check
