Anyway question was good, Maybe Maemo 5 is ready, no need more CSSU updates. I miss TLS1.3 support, but it doesn't have to be CSSU update if it is included with some new browser version.

Maybe it would be cool release Maemo 5 - the final CSSU release. With easy flashing install archive.

Although Leste is already some way better than Fremantle, I afraid it will not ever be better every way, There is lot of sotfware that you sitll need Maemo 5: BlessN900, MilkyTracker, MyPaint, AngryBirds, Bounce...

I think there will be Maemo 5 (with CSSU) users at least next 15 years.
