Strangeness production has been suggested as a sensitive probe to the early dynamics of the deconfined matter created in heavy-ion collisions. In this presentation, we report new measurements of strange hadron (Ks0, Λ ¯Λ, Ξ, ¯Ξ, ϕ) production in Au+Au collisions at √SNN = 14.6, 19.6 GeV from STAR BESII and Ω(¯Ω) production in Au+Au collisions at √SNN = 200 GeV, including rapidity spectra, nuclear modification factors RCP and Ω-to-ϕ ratios. Benefiting from the iTPC upgrade, the strangeness measurements are now extended from mid-rapidity (|y| < 0.5, BES-I) to a larger rapidity range (|y| < 1.0).
