The software is actually a collection of software, each using a collection of libraries.Well, if it helps any, the collective improvements to TACC and Autosteer alone outweigh the minimal limitations ascribed thereto.
Which limitation is it that you find onerous? Or is it the lack of specificity as to what changed from update to update a concern?
While it would be far preferable to have an updated, granular change log (newest on top) with each release, that ain't happening. But just recently they've added a one-line "Minor fixes and improvements." From a process perspective, that's a great thing. So at least you know what not to expect, as it were. Between that and Ingineer's module change list, there's some info.
Separately, I thought the maps updates were separate. I've only gotten 1-2 of those in 19 months.
I was concerned at first when they announced 7.1.x, but after tens of thousands of miles through over 40 states this past year or so, my conclusion is that upgrading to current won't suck nearly as badly as you think.
If you're still concerned, perhaps arranging for a weekend loaner of an AP car from a nearby SvC or gallery might help? That way you could experience firsthand what you'd get...
Just my $0.02.
Each library is a collection of 'methods', basically functions.
The Tesla programmers (like all programmers) don't re-invent the wheel when writing code, they 'call' these pre-built methods again and again throughout their own code.
But it's important to make sure that the library you reference two years ago is still valid, still has the same method you used, and that that method does the same thing as it did when you wrote the code.
When something changes in the library you need to make sure you've checked your code to see if it still works.
The programmers only have enough resources to check a certain number of versions back from the current version, so eventually things stop working on older versions (as those old version start referencing methods that no longer exist, or do something unexpected).
Tesla certainly wouldn't have a team of people selectively irritating non-upgraders,
