I'm tring to be nice, but dude, you're clueless.
Don't want to count OTA updates? Fine. None of the 13 changes to the Model Y were from OTA updates. But, of course OTA updates count. Do they improve the vehicle? In that case, the Y has had many more than 13 changes....in 3 months.

No real changes? How about structural battery pack invented by Tesla. Tabless 4680 battery cells invented by Tesla. Front and rear single piece body castings made from aluminum alloys that Tesla's material science team invented. Heat pump and octovalve (HVAC) invented by Tesla. Tesla invented their own airbags which earned them a 5 star safety rating in every NHTSA test. They design and make their own chips, write their own software code..... I could go on...
Every production line for every vehicle has been re-tooled.
Standard Range Model 3 is available. It's right here:

You can use a lot of adjectives to describe Tesla, but "stagnant" isn't one of them. I don't know where you're getting your info from, but I suggest you check your sources.
