The thermodynamic stability conditions (TSC) of nonadditive and composable entropies are discussed. Generally the concavity of a nonadditive entropy with respect to internal energy is not equivalent to the corresponding TSC. It is shown that both the TSC of Tsallis'entropy and that of the ?-generalized Boltzmann entropy are equivalent to the positivity of the standard heat capacity.
