What is the latest stable version?

Hi!

Is it just me or it's quite hard to find out which is the latest stable version.

Long story:

I have a dm800se, I did a 

root@dm800se:~# opkg update
Downloading http://downloads.pli-images.org/feeds/openpli-3.0/dm800se/3rd-party-dm800se/Packages.gz.
Inflating http://downloads.pli-images.org/feeds/openpli-3.0/dm800se/3rd-party-dm800se/Packages.gz.
....

Then I did 

root@dm800se:~# opkg upgrade
root@dm800se:~#

What? No more updates? Why?

I am running an old version? ShallI update to openpli-4.0?

Is dm800se not getting any updates due to OpenPli not actively supporting Dreambox hardawer anymore?

Thank you for your answers!
