K̄-nucleon interactions near threshold are investigated in the framework of coupled-channels dynamics based on the next-to-leading order chiral SU(3) meson-baryon effective Lagrangian. Accurate constraints are now provided by new high-precision kaonic hydrogen measurements. This constraint permits an updated analysis of the complex K̄N and πΣ coupled-channels amplitudes.
