ChromiumWhat Chromium version am I running?
Read from your browser locally and compared against the current upstream release. Nothing is sent anywhere.
Checking requires JavaScript. You can also open
chrome://version in your browser, which shows the same thing plus the revision it was built
from.
What the comparison means
Only the first number of a Chromium version, the milestone, matters for judging whether a build is current. Chromium ships a new milestone roughly every four weeks and security fixes roughly every two.
- Same milestone as stable. Current, with this cycle's security fixes.
- One behind. Normal for volunteer builds, which need patches rebased onto new source. Usually fine.
- Two or more behind. Missing at least a full cycle of published security fixes, in the program that runs the most untrusted code on your machine.
See how Chromium version numbers work for the full explanation, and updating Chromium for what to do about it.
Finding out more about your build
Open chrome://version. It shows the full version, the revision it was built from, the exact
command line the browser is running with, and your profile path. If you are not sure which build you have
installed, that page is the place to look.
