+# remiod 1.0.1
+
+
+## New features
+* `Ordinal Probit Model`: new model option under `algorithm='jags'`. The option
+  can be requested with argument `models = 'opm'` (or named vectors, for example,
+  `models = c(y1='opm',y2='opm')`). 
+* `algorithm='tang_seq'`: computation is speed up.
+* `get_subset`: function is exported for extracting specified set of parameters
+  from MCMC samples. The extracted samples have a class of 'mcmc', and can be 
+  directly used by functions/packages which take a 'mcmc' object.
+
+
+## Minor improvements and bug fixes
+* Bug fix: when using a J2R imputation of continuous outcome through GLM
+  with `family = gaussian()` using JAGS.
