Today, the first chunks of GNOME 2.6 will start entering Sarge, if nothing strange happens. Things look quite ok right now, with all the autobuilders keeping up to date and with the RC bugs sorted out. The only bit that could be a bit more complicated is the libcupsys transition to gnutls10, as a few big packages are involved: GNOME, KDE, Samba, CUPS and wine. The latter is dragging a dependency for the new alsa-lib 1.0.5 packages, which will probably delay it 5 days or so. There's an RC bug on Samba which could be problematic, but the maintainers probably will do something about it before alsa-lib is ready to go. With a bit of luck, this will go more or less smoothly in, unlike when we did the 2.2->2.4 transition, which was stalled by a series of unfortunate incidents (including the Debian security compromise).
