 - Python 3.6 is now the minimum required version. (Médéric Boquien)
 - The logo has now been moved to the lower-right corner of the figure so that it does not overlap with any information and it has been updated for a less pixelated version. (Médéric Boquien & Rodrigo González Castillo)
 - The wavelength range in SED plots is now dynamically adapted to cover the observed wavelengths. (Médéric Boquien)
+- The uncertainties on the SED plots now correspond only to 1σ rather than 3σ so they do not appear exceedingly large. (Médéric Boquien)
 ### Fixed
 - Make sure we can plot the PDF of equivalent widths. (Médéric Boquien)
 - Fix a crash when generating a mock catalogue containing intensive properties. (Médéric Boquien)
