 \section cl_v302 Version 3.0.2
-- upgraded HPIPM to version 0.1.1, which simplified the interface for getting Riccati-matrices from the solver
+- upgraded HPIPM to a version close to master, which simplified the interface for getting Riccati-matrices from the solver
 - resolved ordering-bug for box-constraints
 - switched back to differential formulation of LQ problems to maintain comparability with other solutions
 - simplified user-interface to the 7 different iLQR-style solver variants
 - removed copied code from external repos (CppAD and CppADCodeGen) and provided install script instead
 
-\section cl_v301 Version 3.0.2
+\section cl_v301 Version 3.0.1
 - enabled compatibility with pure cmake (no catkin or ROS required anymore)
 - fixed bug in explicit template prespecification
 - fixed bug in exporting dependencies on external solvers

  Warning note : When installing blasfeo, a configuration step may be necessary. See https://blasfeo.syscop.de/docs/install/#configuration for how to set the build target to your architecture.
  We advice to run the tests provided by blasfeo to check the correct installation. If not configured properly, blasfeo may be installed succesfully, the CT may be built succesfully with hpipm dependencies, but a "illegal operation (core dumped)" is raised when calling hpipm.
