The firmware version number follows a calendar-based scheme: the first part represents the year, and the second part indicates the week number of the major release. For example, version 24.36 corresponds to the year 2024 and the 36th week starting September 2, 2024. Since 2023, Tesla has consistently released a new major version every 8 weeks. The third part of the version (e.g. 24.36.1) represents a revision or incremental update, which may be released more frequently.
