Version 148.2.4 6/5/2026
Notice something different about the numbers? We're
dropping the '10' prefix from our versioning.
Previously, today's update would have been something like 10.148.4. For a
bunch of boring technical reasons, we're switching to a
[chromium major].version.version format, which makes
this release 148.2.4. This new setup actually allows us
to ship Chromium updates to our beta channel with less friction!
So, it might look like we just skipped ahead 137 versions overnight.
If you're impressed by that, then yes, we are coding time-travelers 🛸.
If not, it's just a naming tweak to keep things running smoothly.
