+Release of V1.0.0, 2017/05/18
+=============================
+
+I feel that musrfit has majored enough to lift it to its first full version, i.e. V1.0.0.
+
+A lot of bug fixing went into it since 0.18.0. It is now also fully ROOT 6 compatible which
+is also the main supported version now.
+
+New features: 
+
+* musrWiz:  a wizard which will help the user to get started to generate msr-files.
+* musrStep: a little helper program which allows to reset the step size of a msr-file.
+            This is useful if you deal with a lot of detectors (e.g. HAL-9500 at PSI).
+* auto-phase correction of Fourier transforms: this is still in its early stage but will
+            eventually provide a real phase corrected Fourier transform, which will allow
+            a real Fourier detector average.
+* the startup file handling has improved substantially.        
+
