WHY are we still at version 68 for mkvmerge?

[MrGrackle]

Hopefully many of you are heeding Cats4U 's advice on replacing key files each time you update your program.
So, WHY is SF still installing version 68 of Mkvmerge? We are now up to version 91. Version 68's file size is significantly larger too, which is odd. Sometimes the random failures on the remux stage seriously might be associated with this.
mp4box is a little more confusing though because it doesn't clearly state what version it is. But, no doubt we are getting an older version of that too, even though the development is not as much as involved as mkv dev.
My checklist after an update always involves:
Replace mkvmerge
Replace mp4box
AND to mod the Amazon amazon_get_season_urls.py script (credit to 0xFeedBeef ) to look at the bookmarked season, not all seasons.

And if you suddenly get a random site issue (usually Netflix), delete associated cookies with that site. Plug this URL into your SF browser: chrome://settings/content/all?search=all+site
Search the cookie by name (Netflix, Hulu, etc) and delete all selected.

Cats4U had a list of programs. Some may matter, some may not.
I did, for a while, replace files, but I find it's tiresome, and I have not done it and the weird thing is SF works.
I do think SF should look into updating maybe once a month to once every 2 months, those programs talked about in the list below.
The only thing is, it's possible some don't even update themselves every month or 2.

aria2c.exe
AtomicParsley.exe
ffmpeg.exe
mkvmerge.exe
mp4box.exe
AND most importantly, YoutubeToMP3Process.exe which is SF modified version of yt-dlp.

But SF won't even fix a major issue with Netflix and the codec selections, so it's just pointless...
