I noticed this immediately after installing 18.104.22.168.126 - Valet mode disable, which used to take at least 15 seconds (server round trip/API delay/limit) after tapping the "Disable" button in the app, now takes about 1 second. Very nice! While there was an app update recently as well, I use valet mode daily and didn't notice the much-appreciated improvement until installing the aforementioned patch. Naturally, there were no release notes referencing the fix. So uncertainty has been created as a result. But again, I use valet mode daily, noticed no improvement after the app update and consistent improvement after the firmware patch release. As far as I know, there is no fob shortcut to enable/disable valet mode (now there's an idea - hold down the front/frunk area of the fob for 3 seconds to enable/disable Valet mode - consider it a feature request, Tesla ). As there is, for example, to open the charge port door (hold down the rear of the fob for a few seconds). This improvement and subtle tracking improvements for TACC are what I've noticed most about 22.214.171.124.126. A close third would be that auto parallel parking seems to have improved as well - initial recognition, specifically. I haven't, don't, and doubt I will find a reason to Summon over short distances. One of the coolest parts about Elon's vision to Summon over long distances will have to be watching the snake chargers in action. He said 2 years or so. Means 5-10 years in mere mortal time, of course, but still it's a great vision.
