what's happening in the world of kde4? well, in the last fortnight or so:
oxygen icons started making their way into svn; kde4 made the switch to dbus after thiago and others worked on it tirelessly for some time now; kdialogbase and kjanuswidget (which most people know from kde application configuration dialogs) is updated after it's 7 year reign with the less mysteriously named kpageddialog which sports both a simple interface like what we had (but with a far clearer API) and a model/view driven option; bits of kservice were moved into kdecore so we can plugin enable things like kconfig and kspell2 (ktrader was also broken into pieces and now we have API-improved traders for services and mimetypes; is also leading up to dfaure implementing the xdg mimetype spec as see on fd.o); applnk/ is on its way out with only the screensavers left to leave (working on it).
akonadi also entered svn, though that may have been more than 2 weeks ago now?
and this isn't even touching on the "usual" progress made elsewhere in the codebase. even old standby apps like ksysguard are getting love and attention, while newer apps like okular (was kpdf) continue to move forward and koffice2 devel progresses nicely.
i've also heard rumours of a possible kde4 scripting (aka "application automation") meeting (ala k3m) being arranged... sweet.
so the pace is quickening. still, there is a lot yet to do. sometimes when faced with such a mountain it's easy to not notice the progress that is being made, even if it is coming along nicely =)
