Gamma-ray lines are traditional smoking gun signatures for dark matter annihilation in the Universe. In regions optimized for large signal-to-noise ratio, we identified a signal candidate for a gamma-ray line at energies around 130 GeV with a post-trials significance of 3.2σ. Spectral and spatial properties are not inconsistent with a dark matter signal. One year has passed since the initial papers, and I give here a brief summary and an update on the status of the 130 GeV feature in the un-reprocessed P7 gamma-ray data of the Fermi-LAT.
