Hi Dmitri, The FixParameter and ReleaseParameter have always been available via the TVirtualFitter/TFitter interface (TFitter calling TMinuit). Some time ago, I also introduced TF1::FixParameter. However, I did not introduce TF1::ReleaseParameter (I will do it). This interface being already available via TF1::SetParLimits anyhow.
