Most of the other Teslas forums have a similar thread regarding firmware update versions so this thread will be specific to Model 3 features that are changed or introduced with each firmware update. If you are a current owner and notice specific features that are revised or added in an update, please post it here and the Mods can update the OP to reflect this. Unfortunately, Tesla Update Notes with each download are notoriously nonspecific in regards to features that are included with updates. Some updates may have no noticeable new features and simply be bug fixes.
OTA firmware updates do not happen with any particular rhyme or reason so it's useful to check here and see if you're running the most recent version. Although there is really no way to "force" an update, it has been suggested that parking around a Tesla service center and connecting to their wifi system sometimes can trigger an update.
