This is the type of update that one wouldn't expect from a polished product. Why release new hardware and software if a stability and general improvement update was just around the corner. I don't like this general attitude of release it now, fix and improve it later.
Because they freeze the software that actually go into the released product WAY BEFORE THE RELEASE DATE.
You don't want at the last minute to introduce some major issue by updating the software that goes in it right up to release. So, you have to accept that some small bugs will go in; as long as there aren't major ones, this is acceptable.
If they didn't do that, the products would wind up with issues that they don't even know how to fix!
That's pretty bad for tech or customer support.
Anyway, that's how it's always done.
During this time, the software continues developing and those small bugs gets fixed and tested, in parallel with product being rolled out.
It's preposterous to you because you're successfully brainwashed into thinking that software deserves to be excused from all preexisting consumer protection laws and engineering sensibility.
Yes, you do have to stop fiddling and ship at some point. But that's not the problem with this industry.
Really, I've worked in engineering for 30 years and unless your release date is extremely flexible (defense maybe...), you accept minor bugs in the system when it is released. If you work on systems with thousands of nodes and several million lines of codes in several integrated products developed in parallel. Expecting no bug would be idiotic unless time and money is unlimited... And even there there is plenty to proof that this is not the case even for those lucky bastards ;-).
So, you freeze everything weeks or months before release; better a well characterized minor bug with a workaround, you tell the client you can fix soon, than a unknown one with unknown consequences you can't fix!
A lot of time, the client is ready to live with the bug, to get the system/product earlier.
We're not talking catastrophic show stoppers here.
