Well, software is like that, except you can keep working on it after you abandon^H^H^H^H^Hrelease it.
Why am I saying this? Because I bit the bullet and released KRN 0.6.9. It has some glaring bugs (like, progress reporting doesn't work much), but then again, 0.6.0 had many more.
Anyway, it is usable, and it shows some of the cooler stuff I've been doing, although most of it is not visible for a user yet.
And besides, I was starting to be stressed about just fixing things ;-)
