I'd suggest a few things.

Firstly, remember the question and answer format and don't make it like an ad. So, ask a question as a confused, lost user would, and answer it likewise

Secondly, make it clear you work for the company - I notice you have it in your profile, but including it in your answer as well.

Third is a general thing. Answers that link to a specific version are slightly lame. Link to a general update page rather than a direct link, so it would be usable should the version go off.

Its unusual, but ought to be fine, as long as you do it right.

I do notice some other non product activity and you've asked nicely, so as far as I go, I'm sure you arn't a spammer for doing this.
