Here are a couple thoughts -

stable - contrasts us with MySQL's latest "add everything all at once"
release.

capable - contrasts us with MySQL's previous "do very little" releases.

free to use and deploy - I get at least on e-mail a week from somebody
wondering whether he actually heard that right.

For what it's worth, "success" sounds better to me than "excitement".
Maybe that's a sign of age.

Cheers,

Ann
