Lennart believes this is a good release for distributions to synchronize on while coming up in Systemd Git in the next few weeks will be a lot of invasive changes coming. There will be major feature development happening again for Systemd 204 and coming soon. One item pointed out by Poettering is that they will likely move systemd from using libdbus1 to the libsystemd-bus library.
Among the features to be found in systemd 203 are improvements to systemd-nspawn, major reworks to the cgroup hierarchy, various new sub-commands and switches, a new sleep configuration file, and much more.
More details on the systemd 203 release can be found -- along with a list of the prominent features -- within the systemd-devel list.
