+# CHANGES in mkin VERSION 0.9-36
+
+## MAJOR CHANGES
+
+- If the ccSolve package is installed, use a version of the differential equation model compiled
+  from C code, which is a huge performance boost for models where only the deSolve method works.
+  Compiled models using the Hockey Stick model (HS) are not supported (yet).
+- `mkinmod()`: Create a list component $compiled in the list returned by mkinmod, if a version
+  can be compiled from autogenerated C code (see above).
+- `mkinfit()`: Set the default `solution_type` to `deSolve` when a compiled version of the model
+  is present, except if an analytical solution is possible.
+- Add some tests for predicting from and fitting differential equation models compiled using ccSolve.
