We present an update of the cosmic ray energy spectrum measured from $3{\times}10^{17}$ eV to over $10^{20}$ eV at the Pierre Auger Observatory.
This energy range is covered by combining data from the surface detector (subdividing the events into a vertical and a horizontal data set), from a denser array of stations and from hybrid events simultaneously recorded by the surface and the fluorescence detectors.
Data collected to date, with a total exposure exceeding 67,000 $\rm km^2$ sr yr, rely on the energy scale provided by the fluorescence detector.
The spectral features, and the impact of systematic uncertainties on their significance, are discussed in detail.
