In a way this blog post is a bit late, since the "big bump" from KOffice-2.2.2 to KOffice-2.3.0 was already a few days ago. But- starting now, we have the brand new zero-day version KOffice-2.3.1 in Gentoo portage, ready for your perusal. Keyword and enjoy!!!
As a side note for those who have not heard it yet, the KOffice 2.3 series will be the last one with that well-known brand name. Owing to certain disagreements and an effective fork of KWord, development will continue as "Calligra Suite", with some less-than-inspired new application names (Words, Tables anyone?). Ah well.
