There is a release schedule of Koffice? It will be usefull to know, for example, when the beta series end, how many RCs they're planning to do, and, the most important to me, the day of the final version.

I'm not asking for a rigid schedule, it's just a prevision, that the developers can share with the community.

This is where I find out about the release schedules. Hope it'll be useful for you.

We can't plan the number of RC (ideally it should be "one" a RC is supposed to be the real deal after all), and therefor we can't plan the final release either, ideally the finale (or RC2) release will be something like three weeks after RC1. As mentioned by irshad, the wiki always contains up-to-date official information about releases. (the introduction text is a bit outdated... going to edit)

Wow, KOffice 2 is coming much faster than I expected!
