No, it won't. PLaneT has a strict "no magic upgrades" policy.

PLaneT remembers what version a particular file got the first time it
did the require and it gets that version in the future, even if there
are new versions released. You can clear that linking with the planet
commandline tool, or you can edit the require line to insist on a
version that is at least a certain minor version, tho.
