 CHANGELOG
 =========
 
+0.5.0 (March 20, 2020)
+----------------------
+This release adds two EXPERIMENTAL flags:
+--normalize-betas and --no-signal-scaling.
+I'm especially unsure about the behavior of
+--normalize-betas in combination with any hrf that contains
+"derivatives" or "derivatives + dispersion", since I'm unsure
+when to divide the the beta estimates with the variances of
+the beta estimates to derive the t-statistic
+(i.e., normalizing the beta estimates).
+This release also has given access to residuals from the LSA and LSS
+interfaces.
+
+Another WARNING: residuals for the LSS interface are not quite as meaningful
+since I'm averaging the residuals over all the models being generated.
+This project is not version 1.x.x yet, so be aware aspects of the API
+may change rapidly.
+
+Thanks to @michaelmack for opening an issue to suggest new features and
+@PeerHerholz for their contributions!
+
