The TOTEM experiment has made a precise measurement of the elastic proton-proton differential cross-section at the centre-of-mass energy 8 TeV based on a high-statistics data sample obtained with the β*=90 m optics. Both the statistical and systematic uncertainties remain below 1 %, except for the t-independent contribution from the overall normalization. This unprecedented precision allows to exclude a purely exponential differential cross-section in the range of 0.027<|t|<0.2 GeV**2 with a significance greater than 7 σ.
