New and conventional bottomonium states

Recent progress on the bottomonium states is reported. This talk briefly reviews the observation of $h_b(1P), h_b(2P), Z_{b1}^+, Z_{b2}^+$ states, transition of $h_b(nP)\to η_b(mS)γ$ and new studies on the $η_b(2S)$ state. Other $η$ and $π^+π^-$ transitions of $Υ(nS)$ are also discussed.
