  We study the possible types of future singularities in the isotropic
homogeneous cosmological models for the arbitrary equation of state of the
contents of the Universe. We obtain all known types of these singularities as
well as two new types using a simple approach. No additional singularity types
are possible. We name the new singularities type "Big Squeeze" and "Little
Freeze". The "Big Squeeze" is possible only in the flat Universe after a finite
time interval. The density of the matter and dark energy tends to zero and its
pressure to minus infinity. This requires the dark energy with a specific
equation of state that has the same asymptotical behaviour at low densities as
the generalised Chaplygin gas. The "Little Freeze" involves an eternal
expansion of the Universe. Some solutions can mimic the $\Lambda$CDM model.
