  In this note we compute Leibniz algebra deformations of the 3-dimensional
nilpotent Lie algebra $\mathfrak{n}_3$ and compare it with its Lie
deformations. It turns out that there are 3 extra Leibniz deformations. We also
describe the versal Leibniz deformation of $\mathfrak{n}_3$ with the versal
base.
