Subscribing ubuntu-release for a feature freeze exception.
I'm still in the process of preparing this update, although much of the work has already been done in Debian experimental. By the time I'm ready to upload, I will have ensured that the installer still works, and tested gparted.
The main rationale for this update is support for logical sector sizes other than 512 bytes, which are common on SSDs and are expected to become increasingly common over the lifetime of Ubuntu 10.04 LTS. I don't want to release without support for these.
