in this commit:
603e015
the regex for checking if a recent year is in the password was changed to include future and more present years.
While this is probably better, it is not in line with the original zxcvbn library:
https://github.com/dropbox/zxcvbn/blob/67c4ece9efc40c9d0a1d7d995b2b22a91be500c2/src/matching.coffee#L38
As such if you rely on both your front and backend to do these checks, then a password like this:
xvjcz2025
is a 2 on the php version, but a 3 on the javascript version.
