You're probably used to semantic versioning. OpenClaw uses Calendar Versioning (CalVer) instead. The format is YYYY.M.D.
Take 2026.2.24 as an example. 2026 is the year. 2 is the month (February). 24 is the day of the month. This tells you exactly when the release was cut. Same-day hotfixes get a -1 or -2 suffix.
To see your installed version, run openclaw status. To check the latest available version, run npm view openclaw version. If those two don't match, you're behind.
