Apple just rolled out the final build of iOS 11.3 to the general public. Its build number is 15E216.

Should you update?

Yes, I recommend upgrading to iOS 11.3 final version to all users who are currently using an outdated beta version.

The older beta builds contain a lot of bugs, which are no longer present in the final update.

For those of you who are interested in a jailbreak, stick to the lowest firmware possible. Anything below iOS 11.2.6 will be fine right now.
