I'm currently using the Horde projects IMP, DIMP, MIMP, Ingo, Kronolith, Mnemo, Nag, Turba and Sork. I ignored the (rather outdated) Debian packages and installed the upstream versions.
A few years later, my Horde installation is a bit outdated and I consider updating each project and each version individually a pain.
The Debian stable packages are as outdated as ever, but squeeze will deliver reasonably current versions, so I'm considering switching to the Debian packages as soon as squeeze is released.
What would you recommend for software packages like Horde? Using the upstream versions and manually updating or using the distribution's packages?
