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 25.42 corresponds to the year 2025 and the 42nd week starting October 13, 2025. Since 2023, Tesla has consistently released a new major version every 8 weeks. The third part of the version (e.g. 25.42.1) represents a revision or incremental update, which may be released more frequently.
