Ask HN: Include bug fixes in release annoucements?

We're closing in on our first product launch (http://timepanel.net). One of our goals is to let users, or potential users, know that the product is aggressively developed, and well maintained. Thus far, we've only announced updates for each beta milestone we've reached, which have consisted primarily of new features. However, in the most recent update announcement, we also included bug fixes that weren't in the previous release. In regard to that, I have 2 questions:

1) As a user, do you prefer to see bug fixes in release announcements?

2) Sometimes we spend a considerable amount of time on bug fixes, and we want our users to know that even though new shiny features aren't landing, that we're still actively maintaining the product. So, if enough bug fixes have accrued, is there anything wrong w/announcing a new release comprised only of those w/out any new features?
