     6Changes:[[BR]]
     7 * New filter method: LEnKF - The classical Ensmeble Kalman Filter with covariance localization (filtertype 8)
     8 * New filter: NETF (Nonlinear Ensemble Transform Filters by Toedter and Ahrens (Monthly Weather Review 143 (2015) 1347-1367) including smoother extension (filtertype 9)
     9 * New filter: LNETF - NETF with local analysis and observation localization, including smoother extension (filtertype 10)
     10 * revised memory counting to work with more than 2.1 GB per process
     11 * New routines for ensemble generation: PDAF_eofcovar and PDAF_sampleens. These routines simplify to generate an ensemble with second-order exact sampling (see [wiki:EnsembleGeneration documentation on ensemble generation] and documentation for each routine linked on that page)
     12 * New routines for ensemble diagnostics (histograms, skewness and kurtosis, effective sample size). (see  [wiki:DataAssimilationDiagnostics documentation on data assimilation diagnostics] and documentation for each routine linked on that page)
     13 * Bug correction: forgetting factor in EnKF smoother was treated incorrectly
     14 * Bug correction: SEEK filter in single-precision case showed an issue
     15 * Additional functionality for Lorenz-96 test case: model error can be added to the integration and incomplete observations are supported.
     16 * revised ensemble generation in testsuite for EnKF with dummy model: for ensemble larger than state dimension a random sampling is now used, while for ensmeble up to the size of the state the mean-preserving intialization as before is used.

    928 * The Makefiles for the testsuite cases are cleaned up to avoid the warning about the missing directory dummympi/ (The directory doesn't exist any more)
    1029 * Typo corrections in screen output of the PDAF core routines
