 ## Features
 
+-   Added fuzzy string matching for parameters and variables ([#796](https://github.com/pybamm-team/PyBaMM/pull/796))
+-   Changed ParameterValues to raise an error when a parameter that wasn't previously defined is updated ([#796](https://github.com/pybamm-team/PyBaMM/pull/796))
 -   Added some basic models (BasicSPM and BasicDFN) in order to clearly demonstrate the PyBaMM model structure for battery models ([#795](https://github.com/pybamm-team/PyBaMM/pull/795))
 -   Added the harmonic mean to the Finite Volume method, which is now used when computing fluxes ([#783](https://github.com/pybamm-team/PyBaMM/pull/783))
 -   Refactored `Solution` to make it a dictionary that contains all of the solution variables. This automatically creates `ProcessedVariable` objects when required, so that the solution can be obtained much more easily. ([#781](https://github.com/pybamm-team/PyBaMM/pull/781))
