I'm puzzled, your first post was about release notes which talked primarily about the MCU, the second post points to a website that talks about supercharging in general. Neither seems to answer the question on batterygate and chargegate. What topic are you trying to help explain?
Software release SW: 2020.48.26 was said to unwind the restrictions after finding the post again (where the owners group were taking credit for making Tesla revert which doesn't seem to have happened, they like to claim success on everything which is why I never contribute to them, but moving on.. /mini rant off) .
I've not followed all the in's and out's of this since as it doesn't impact me, but sadly based on your software release it looks like you may not be one of those who benefitted. Never say never and when you get a 2021 software release things may improve but I would resign yourself to what you have. Far too many people live day to day in anticipation of whats to come when it comes to Tesla, ask anybody who bought FSD back in 2017!
Just on software releases, if its not self explanatory the naming convention is year.week.build ie 2020.48.26 would be from 2020 and the 48th week and be the 26th build that week (I imagine not every build actually gets pushed out to owners).
