I never thought that I would teach English for native English speakers even for a second, but

meaning no. 5 of “stop” at www.oxfordlearnersdictionaries.com/.../stop_1

”for short time

[intransitive] to end an activity for a short time in order to do something”

“ We all know that Oxford dics are of high quality, but just to be sure I checked the others like thefreedictionary and found the same. Stop(ped)” does not always finality. If it did, then a bus could not stop in a bus stop, just pause there. :-)

It was an elegant way, I like it.

In English, in the context of talking about a product that a company makes, if you say they stopped producing it then it 100% means they STOPPED producing it, in other words, they have discontinued production. They've ended it. 

"Stop" is not the correct word for this context, regardless of whether or not it is synonymous with "pause" in other contexts, such as stopping at a stop sign.

English is a tricky language, I don't fault you for not knowing that, but it's silly to argue this point if you you aren't really familiar with nuances of context.

Fully off:

But you all mentioned “stop” as a transitive verb, eg. with a gerund as a direct object, like you did in “stop producing it”.

My imperfect (as you concluded) sentences were 

“The whole discussion started about why there are no improvements nowadays. Why have the releases stopped?”

I used “stop” as an intransitive verb, as buses come and stop, I meant in the similar way that releases/updates can come (arrive) and stop.

When one regards these latter nouns as virtually “moving” things, I mean things  appearing then later not appearing, cannot you use “stop” similarly to buses as moving objects?

Like in “updates stop appearing”?

PS: Sorry, but my browser does not let me use grey colour, just black, here in Garmin forums.

It's possible that Garmin is preparing features from Pro to non Pro Gen².

Exactly. In fact a new beta was released today bringing in many of the Pro features.
