No one said that. All I'm sayi....
Well, I think there's a misunderstanding. My question should be "does it make sense to update to THIS latest release" or wait for the next because some people here mentioned to wait because this special one is crap? That might happen seldom but sometimes it happens.
And yes, I agree with you, there's never ever a bugfree firmware. Some people here in this forum swear by the Agilent / Keysight and take them to skies but my experience in the lab with different Agilents / Keysight scopes show me without surprise that even these scopes have bugs in the trigger unit, problems with saving pictures to a stick etc.
I'm a development engineer for embedded and started in 1981 with an ZX81 during the home computer era, later on studied communication electronics. To my opinion it's absolutely OK if devices with complex firmware / software have bugs, can't be avoided but only reduced to a minimum. More important is a good and reliable support which offers updates to fix the know issues. As long as this is guaranteed everything's fine!
Concerning the DS4000 series I think they are good scopes. It works reliable and does not have more or less bugs than other manufacturers have got, too.
By the way, my very expensive Agilent multimeter 1242 of the first series which I've bought around 2008 is broken meanwhile although I didn't use it very often. Switching it on shows a voltage of approx. -2V and when switching to resistor measurement it is spinning from max to min permanently. I replaced it with a UNI-T for about 80,-€.
So, I'm generally satisfied with the DS4000.
Would appreciate not to spread my address and email to different companies, too much data mining today. The reason, why I asked for the firmware here in the forum first instead of contacting Rigol. It's only my personal opinion, no criticism if others think different.
Have a nice day,

When will the forum get decent quotation functionality???
