Since "life is what happens to you while you're busy making other plans", our announcement regarding RC 2.5.9 was a bit premature. Sorry for the confusion. But the RC is now out since yesterday and we'd be super happy if you could throw it onto your projects, test it and report back to us, so that we can finally release Kirby 2.5.9 next week. Check out the changelog where you'll also find the download link.
